Mini Hygrometer Thermometer

Great Value for money. Placed around home it is easy to monitor humidity and temperature around the home. Temperature is accurate when they are placed together in the same location the reading are within 0.2degC. The Humidity readings are 3 % different when all placed in the same location. However they humidity reading is very useful for monitoring kitchen and bathroom for excessive humidity.

I bought these thermometer/hydrometers to put in some of my reptile enclosures to help keep an eye on humidity and temperature without having to test the enclosures. They seem fairly accurate, are easy to read, and a good size. Batteries are removable to be replaced easily which is great. Perfect for my use!

Product okay but batteries were already in use so no way of telling how long they will last.

I got these for my Bambu Lab AMS, and they work great! I 3D printed small baskets to hold them and mounted them inside the AMS, and they fit perfectly. They give quick and accurate humidity readings, which is super useful for keeping my filament in the right conditions. For the price, they’re a great little addition to my setup. Easy to read, reliable, and super handy for anyone managing filament storage. Definitely recommend.

Not very accurate but it does the job if it’s not used for a critical setting. I use them for my 3D printer chamber and AMS where accuracy is not critical.

Purchased a pack of 5 of these temperature/humidity sensors to monitor humidity levels in a renovation property. They actually arrived individually packaged in single unit, plain white boxes. When opened, each of the units was on and operating. One unit arrived with an almost completely flat battery (far left in the picture). How long the others will last before requiring replacement batteries is anyone's guess. The temperature across the 5 units read a variation of less than 1 degree, which I find acceptable for something of this cost. The humidity reading between the 5 units varied by 8% (assuming the variation remains constant over the whole range) which I find less acceptable. The worst aspect of these units is the inability to mount them effectively. My initial though was to use double-sided tape but I feel that this would render the units completely pointless as it would block the sensor opening and prevent them from working. All things considered, these items will be returned for a refund. Being sent with a flat battery is unacceptable and the inability to mount these effectively makes them unusable for my needs. I wouldn't have returned just because of the accuracy issues as they're intended only as a guide, they're not precision instruments.

It's isn't too accurate but it's good enough

still going well after several months. surprisingly accurate and agree with each other and calibrated thermometer.

I cinque termometri/igrometri del set hanno una notevole precisone, in quanto presentano differenze l'uno dall'altro di +/- 0,1°C e +/- 1% per l'umidità. Circa l'accuratezza (la vicinanza al valore reale) non posso dire molto, in quanto non dispongo di strumenti con accuratezza elevata (comunque 0,2-0,3°C la differenza con un termometro a mercurio abbastanza affidabile). Assolutamente economico il prezzo. Utili per monitorare la differenza di temperatura/umidità fra diversi locali di un appartamento o villetta.

2 stuks gekocht, welke van de 2 geeft de juiste informatie aan???

Compré estos para medir la humedad de mi filamento de impresión 3D, que guardo en cajas herméticas después de secar el filamento por primera vez. Funcionan perfectamente y, sorprendentemente, los 5, en un par de horas desde que los abrí, se estabilizaron y mantuvieron exactamente las mismas lecturas. En las fotos, verá cómo los monté dentro de cajas herméticas de cereales de 4 litros nuevamente de Amazon. Diseñé un soporte simple que usa velcro autoadhesivo para sujetarlo al fondo de la caja en lugar de tornillos que puedan dejar entrar la humedad. Además, es fácil quitarlos para cambiar la batería. El segundo video muestra cómo se imprime en una Bambu A1 mini sin problemas en 15 minutos a velocidades increíbles. La lectura del medidor es alta porque la caja de la foto está abierta. Para mí, estos medidores funcionan perfectamente, el único problema es que en un medidor la batería estaba agotada, pero no fue un problema. ¡No esperaba que tuvieran baterías! ¡Me gané un premio!

Fungerar bra, kanske inte 100% exakt men ger en bra indikation om temp och fuktighet. Den ena har tappat det och visar 20-30% fel i fuktighet
