AOSONG Temperature & Humidity Data Logger Hygrometer & Thermometer

Description

Temperature range: -20℃~+60℃ (external sensor: -40~+80℃) Temperature accuracy: ±0.3℃ (-25℃) Temperature unit: ℃（Celsius）/℉（Fahrenheit） Humidity range: 0~99.9%RH Humidity accuracy: ±2%RH Resolution: Temperature: 0.1℃ Humidity: 0.1%RH Sensitivity decay: Temperature: less than 0.1℃ per year Humidity: less than 1%RH/year Records: 12800 (Max) Records interval: 10 - 18S adjustable Records interval delay: 10 - 18S adjustable Voltage: Battery: 3.7V USB: 5V Power: Build-in Lithium battery (rechargeable) Communication Port: USB mini port Battery lifetime: At least to be used for 1.5 year if full recharging without any button and buzzer operation using external temperature sensor If use temperature and humidity sensor, could be used for one year if full recharging without any button and buzzer operation Working Environment Temperature: Data logger: -20℃~+60℃ External sensor: -40 - 80℃ The LCD will have slow reaction low temperature, however, it will have no influence for normal testing. It will show normally when temperature resume
