Habe mir gleich 6 Stck bestellt um die Temperatur und noch wichtiger die Luftfeuchtigkeit in mehreren Rumen zu kontrollieren die Teile sin sehr genau ( habe Vergleichsmessungen gemacht) gut abzulesen
und stren nicht von mir 5 Sterne
I got this thermometer as my son was born 10 weeks early and I needed to make sure the temperature of the room was in certain limits, so he was able to maintain his own body temperature.
This was really well priced and and has been pretty accurate
It has been increadibly helpful to make sure my house is kept to the right temperature for my son, while hes still tiny
les 6 produits ont t mis dans les 6 pices de ma maison
La temprature est conforme celle de mon ancien thermomtre
Pour l’hygromtrie, je n’ai pas de recul mais je fais confiance
Je recommande ce produi
Design ist hier klar Geschmackssache. Display sehr gut ablesbar. Bei allen sechs Gerten ist die Anzeige relativ gleich mit genauen Daten (mit weiteren Drittgerten abgeglichen). Die Qualitt der Gerte ist gut so wie beschrieben, sowie die beiliegenden Batterien. Die Beschreibung passt voll auf die Produkte zu. Bin zufrieden. Wrde die Gerte wieder bestellen. Zur Haltbarkeit kann ich noch nichts sagen, weil gerade in Betrieb genommen.
Not as big as they look but that doesn’t matter. I have 4 in a Caravan to monitor temperatures in each compartment and use my heaters more cost effective.
All 4 put together give the same readings within .1 of a degree. Outside temperatures were the same as the Met office readings. I highly recommend you get one in each room because central heating thermostats do what they want , these should help you tailor your heating manually.
This does what it says. Easy to use and you don’t need to get any batteries as they are included. You get it out from the box, turn it on and done. Sleek design.
Da wir gebaut haben und noch Baufeuchte in den Wnden steckt, wollen/mssen wir die Temperatur und Feuchtigkeit in den Rumen im Blick behalten – dank dieser sehr preiswerten Thermometer ein Kinderspiel. Batterie einlegen (mitgeliefert, sollen ein bis zwei Jahre halten), fertig – die Messwerte werden in groen, leicht ablesbaren Ziffern angezeigt, die kleinen Gerte wirken wertig und unauffllig, kein einziges wies einen Fehler auf. Kann ich nur empfehlen.
Reu ce jour et j’ai mis les 6 l’un ct de l’autre pour vrifier la fiabilit, j’ai maximum 0,2 degrs d’cart entre 2 thermomtres et max 2 % d’humidit d’cart donc on peut en conclure que la fiabilit est bonne.
I only bought this to check the heating box (as above) I didn’t realise it also had a room humidity monitor on as well which really has been good for my copd!
So all round it’s a really good product.
Great value for money. Highly recommend this produc
I’ve put one of these in every room. You get batteries with the device. Just slot them in and stick the magnetic monitor somewhere for example on the fridge. It tells you the temperature and humidity level in big, clear numbers. It shows a grumpy looking face if not ideal and a smiley face if the levels are good. Simple, easy to use device that does what you expect it to do. Useful for avoiding damp and mould in the home. I use them to decide where and when to use the dehumidifier.
All four thermometers showed the same readings within a small percentage error. They are ideal for checking room temperatures when setting up heating systems. All in all a good purchase at a very reasonable price.
This is compact and perfect for when you need to keep track of the indoor temperature and humitity. I have recently purchased a second one which I took on holiday. The first one is over 1 year old and still going strong. Highly recommend this item, it is ideal!
Arrived quickly and was well-wrapped. Easy to use. Have no way of judging its accuracy really but it adjusts pretty quickly to a different environment and the readings confirm more or less what I’d expect in each room. Pleased with the purchase.
It broke after one week.
Edit: customer service contacted me and sent me a new one on express delivery free of charge, I did in the mean time buy the next model up but can’t fault them at all. FYI, replacement hasn’t broken.
Would buy again.
This device is as accurate as I need it to be which is fine as far as it goes. I have no means of checking its accuracy but as the photo shows, the room temp at the time the photo was taken on 24th July at 14:15 looks to be reasonably accurate on a rainy day. I have emphazema and also am on blood thinners so I need to know what temperature any particular room is in order to not feel the cold which can worsen my condition. This device does the job.
I am glad I bought it, but I wouldn’t rely on it for extreme accuracy as I don’t think it is really meant for that. It is what it is and is good enough for me personally.
Thermometer works well and the moisture in the air shows the same as my dehumidifier. Works well, nice and compact.
The only thing that made me give it 4 stars is that it doesn’t have a standard or something. You just have to keep it balanced upright, so it’s easy to accidentally knock it over.
I tested the thermometer with different voltage levels (provided by a programmable DC power supply). It seems to be able to operate between 1.0V and 1.65V but the lower the voltage the lower the contrast of the LCD screen becomes. At 1.4V the drop in contrast isn’t significant so using the same AAA alkaline battery for two years (like I did) isn’t an issue. At 1.3V there is a noticeable drop in contrast: the segments are semi-transparent/grey instead of sharp black. At 1.1V the LCD screen is barely readable. For the above reasons using 1.2V or 1.25V rechargeable AAA batteries might not be a good idea.
Viewing angles: the LCD is sharpest when viewed from top/left/right, a bit less sharp from the front and significantly less sharp from bottom. Very typical design in case of segmented LCD displays.
If I leave my two TP49 and two TP50 thermometers on my desk to let them stabilise then their temperature measurements are very close. The difference between the lowest and highest reading is at most 0.2C (but sometimes all of them show the exact same readings) and they seem to agree with my mercury thermometer too. The difference between the lowest and highest humidity measurements can be up to 7-8%. Three of the thermometers are very close to each other (within a 3% range) but one of the TP50 units provides a noticeably higher value when the humidity is above 50-60%. At lower humidity (30-40%) the spread between the measurements isn’t as high. Most of these seem to satisfy the claimed specs (1C and 2-3%RH) except the humidity readings on one of my TP50 units. (However, in case of humidity most people don’t need very accurate readings.) This isn’t military-grade precision but I don’t expect much better from an inexpensive consumer-oriented device. The downside to this is that you may get a dud if you buy only one unit.
Comparing the TP49 (this model) to the TP50: the most obvious difference is that the TP50 is a bit larger (both the display and the frame around it which includes thickness of the device: 2.0cm VS 1.5cm) and it remembers the lowest and highest readings since the last reset. In terms of design there are pros and cons on both the TP49 and the TP50 side:
The reflective LCD background of the TP50 is lighter which seems to result in a bit better contrast. However, I prefer the LCD of the TP49. My problem with the TP50 is that with a full battery (1.5V or higher) the inactive LCD segments become too visible when I look at the display at an angle (45+ degrees from the left/top/right). I prefer the display layout of the TP49: it shows the temperature at the top of the screen. The TP50 shows the humidity at the top (with a bit larger/taller numbers than what it uses for the temperature value and I find that a bit annoying).
The design of the battery cover of the TP49 is inferior. Opening the battery compartment requires only a minimal amount of pressure on the central snap-fit joint that is easy to apply accidentally by simply picking up the thermometer. Without touching that area the lid seems to be secure enough. The TP50 changed and improved the design of the battery compartment significantly.
Unlike the TP50 the TP49 can be attached to the head of a screw or nail. The magnet in the TP49 is smaller and shiny, it is located at the centre instead of the top. Attaching it to a flat surface with screw/nail or magnet obstructs the holes on its backside and that might affect it readings or the speed at which it follows changes to temperature/humidity. The TP50 has a larger dark ferrite magnet at the top: even after attaching it to a flat surface there is a 1mm gap for the ventilation holes on the backside.
Both the TP49 and TP50 have a 10 second refresh rate. This seems to be a reasonably good balance between battery life and response time. Their power consumption patterns seem to be very similar: both models spend about 7 seconds in idle and 3 seconds with reading the sensors and updating the info on the screen (during a full 10 second refresh cycle). Based on my measurements the TP50 seems to consume a bit more.
