The VWR® Traceable® Logger-Trac™ RH/temperature datalogger is an ideal tool for monitoring material in transit, with a variety of intuitive programming functions and features.

• Displays cumulative alarm duration from user-selected min./max. temperature values
• Reusable/re-programmable
• Perfect for monitoring material during transportation
• Integrates with maxithermal software for complete data analysis
• Alarm set points (temperature only)
• Recording interval (temperature/humidity)
• Start delay and stop key enable
• User may set time zone

LCD shows the running alarm tally based on the acceptable humidity/temperature range and recording interval. Alarm tally is incremented when readings move outside parameters during the recording interval.

For complete flexibility, the user-defined recording interval may be set based on the number of desired days to log (from 4 hours to 365 days), or the desired time interval (from every 2 seconds to every 24 hours). Internal flash memory stores 7680 readings. To ensure no data loss, the thermometer/hygrometer will stop logging data once the memory is full (data will not be overwritten). While recording, the following information is displayed: current relative humidity and temperature, min./max. temperature achieved, and cumulative running time. Once an alarm condition has occurred, the following additional information is displayed: Alarm Tally, “ALARM” notification, and cumulative alarm time.

The user may select the acceptable humidity and temperature parameters (high and low values) in 1% or 1° increments. The cumulative alarm duration timer is started each time the humidity and/or temperature reading is outside an acceptable parameter, providing a total excursion time from the start of recording.
