Works Great
Bought this to replace several floating pool thermometers that leaked and failed. Fed-up with floating thermometers, I tried this and I can read the pool temp from in my house any time. Accurate to.05 degrees. pairing and set up was easy. Translation of the instruction were just enough to understand.
Works great! Accuracy is ok.
Easy to install, reasonably priced, wireless works well. Accuracy is a bit off by about 1.5C (3F) which is why I gave it 4 stars rather than 5, but whether itâs -8.5C or -10C outside is fine with me. For remote monitoring of an outdoor structure like a greenhouse or chicken coop it works fine. The remote probe only transmits temp and the remote transmitter station provides temp & humidity. The receiver inside the home is always on and alternates display between remote base transmitter (outside structure) and remote probe (inside structure). The receiver in the home also constantly shows temp and humidity inside the room where it is wall-mounted. AAA batteries are used for power. If your accuracy spec is approximately +/- 1.5C (3F) then this product will do the intended job well.
Good Remote Temperature Monitoring
This is the second unit I have bought and use it for remote monitoring on our deep freeze temperature. Te unit provides Indoor and Outdoor Temperatures as well as an additional external temperature via the wired temp probe. The wired temp probe can be immersed in liquids to monitor the liquid temp. The 1st unit I bought is used to monitor a heated water tank during the winter to ensure the water does not freeze. Overall, I am very pleased with the performance on these units.
Efficient easy to use hygrometer.
Very easy to use and set up. I wanted an actual digital monitor and reader and not Bluetooth so I can always see the readout and this product works great. I love that it shows the humidity levels in my small countertop greenhouse and also in my home in general.
Control health of home and family
Inkbird ITH 20R Digital Hygrometer Thermometer given as Christmas gift to young family in new home.Told by family the gift has help keep home warm without adding excess humidity to home. Saves money
Works well
Used it for my home brew setup, BIAB. The external probe worked great at first but there was a bit of a delay in the temp change that caused me to overshoot my mash temp. Good for a starter setup but might upgrade to something more accurate in the future.
Vachement déçu
Il n’est pas fiable, les instructions d’utilisation ne sont pas claire et rend l’utilisation trop compliqué pour ça fonctionnalité.. Au bout d’une semaine le senseur commence par inscrire des lectures biaisé et au bout d’une semaine supplémentaire il ne fonctionne plus. Je me laisse la chance de croire que JE suis sans doute tombé sur LE thermomètre du lot qui était mal fonctionnel.
Itâs ok
Itâa ok – but â¦.For my usage situation not great, display keeps alternating the displayed info between the probe and the sensor the probe is plugged into. I just wanted one to stay on screen so had to disconnect the probe. Did not find a way to stop the alternating display
