The Temp Tracker is a versatile Temperature and Relative Humidity indicator with useful alarms and serial output. Measured values are displayed on the front panel: temperature on the left, relative humidity or dewpoint on the right. Maximum and minimum values are saved and can be viewed at any time. The Temp Tracker includes the following useful features: fully-programmable alarms, calibrated voltage outputs, and RS-485 output. Input for the Temp Tracker is supplied by Model 41382LC Relative Humidity/ Temperature Probe which provides a convenient 4-20 mA current loop signal for each channel.
