Humidity data-logger ValProbe RT

temperaturefor storagefor humidity traceability

Overview
The Kaye ValProbe RT humidity/temperature data logger uses RF technology to deliver real-time measurements to the Validation Console. Measurement ranges: humidity 15%–95% RH; temperature 0°C–70°C. Digital sensor technology and optimized electronics provide accurate readings and extended battery life. Sampling is operator-programmable from 1 second and each sensor can record up to 100,000 data points in non-volatile memory.

Field-replaceable sensor
The ValProbe RT features a field-replaceable digital RH/T sensor to enable fast, cost-effective replacement without returning the entire logger. Sensors are shipped pre-calibrated to ensure measurement traceability and consistency.

Easy verifications in your lab
Temperature verification is simplified by attaching the 1 m sensor extension cable and using a dry-block calibrator (e.g. Kaye LTR-150) to validate multiple loggers simultaneously. The ValProbe RT software supports automated multi-point temperature checks. For relative humidity verification, portable humidity test chambers allow simultaneous evaluation of several ValProbes; the software supports automated humidity verification and automatic report generation.
