U12 Temp/RH/Light/External Data Logger
Onset HOBO Four Channel USB Temperature/Humidity/Light/External Input Data Logger
with 12-bit resolution
 The temperature, RH, light with external input logger is a four-channel electronic recording device that provides temperature, relative humidity, relative
indoor light level measurements and accepts one external input.
The external channel accepts a wide range of external
sensors and input cables for temperature, CO2, AC Current,
4-20mA, and DC Voltage. The data logger
features 12 bit resolution, high accuracy, data storage of 43,000 samples and 1 year user-replaceable battery.
