THT-HR Data Logger
Qs_rbbr.gif (1971 bytes)The THT-HR is a small Three Channel High Resolution (12 bit) Humidity and Dual Temperature Datalogger. The humidity and internal temperature sensors are housed in a 60 micron Stainless Steel filter at the top of the logger. The external temperature sensor is in a stainless steel insertion probe connected to the logger by a 1.5 metre tefsel cable.
