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

Active LCD display technology allows the duration (cumulative time) for the temperature excursion to be viewed on the display immediately, without the need to download data. It has unit description.

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.
