The Kaye RF ValProbe temperature/ humidity data loggers are wireless instruments designed to work as either standalone units or with the LabWatch LT environmental monitoring system. Featuring external temperature sensors, internal RH sensors and optional auxiliary inputs, the RF ValProbe is intended for the validation and monitoring of environmental chambers and storage areas (i.e. stability chambers, freezers, refrigerators, warehouses, etc).

The RF ValProbe can store up to 10,000 samples per sensor. The data is transmitted via a 2.4 GHz RF Mesh network to the base station and LabWatch LT equipped computer where the data from multiple loggers is combined in a single file from which reports are generated. These reports are designed for implementation of 21 CFR Part 11 requirements for electronic records. Users can customize the reports by defining process cycles and specifying cycle-based calculations. The data is also stored in both the logger and base station memories providing multiple redundancies for ultra-reliable storage of critical information.
