These loggers travel with shipments to track relative humidity and temperature. 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). To ensure that no data is lost, once memory is full the thermometer/hygrometer will stop logging data (data will not be overwritten).

• User-selectable humidity/temperature parameters (high and low values) in 1,0% or 1,0 °C increments
• Displays cumulative alarm duration
• Current RH and temperature, minimum/maximum temperature achieved, cumulative running time
