Review on 🌡️ iKKEGOL Dual Sensor LCD Display Digital Thermometer Hygrometer for Indoor and Outdoor With Memory of Max Min Readings by Brandon Frogge

Great value (I bought two (2) for home brewing) and they are accurate to 0.9F in a 32F ice bath with an accurate lab thermometer. At room temperature both read 66.0 F and 40% RH (see photo) and the lab thermometer also read 66 F (exactly). I haven't verified the relative humidity accuracy as I don't use that feature, but in the photo they both read the same thing. Resetting the Hi and Lo readings is a little cumbersome as pressing RESET resets the units to degrees C and needs to be changed back to degrees F. The diameter of the outer probe (excluding the surface mount bracket) is approximately 0.157" or approximately 5/32". Fits easily in my 1/4" thermowell on fermenters. NOTE. Outdoor humidity is NOT measured unless the entire unit is outdoors, NOT just the sensor.
