The CT485B is NO LONGER AVAILABLE, Please review our LATEST CTXL SUPERECORDER™

The Model CT485B completely self-contained temperature/ relative humidity recorder is microprocessor based to accurately measure, indicate and record temperature and relative humidity.

This rugged unit comes standard with alarms. They contain a single, integral relay contact which closes in response to an alarm condition. Simultaneous high and low alarm points for temperature and relative humidity are user selectable. When the current conditions exceed any of the preset values, the 2 Amp relay contact closes and an audible alarm sounds. A power adaptor (115VAC or 230 VAC +/- 10% , 50/60 Hz) is supplied for continuous long-term operation, along with four D-cell batteries for backup power or field use.
