Kaye RT Valprobe

Kaye RT Valprobe (Real Time)

Kaye ValProbe® RT (Real-Time) is a wire-free real-time process validation and monitoring system designed around the measurement and reporting requirements of the most intensely regulated industries.

It is a state of the art validation system design that meets industry and regulatory (FDA / GAMP) requirements for thermal validation. The ValProbe RT system combines high accuracy measurements, automated sensor calibration, an intuitive metro style user interface, and extensive reporting to simplify the complete validation process.

Kaye ValProbe RT is the successor of the widely recognized Kaye ValProbe, the accepted standard in wireless validations systems for over 15 years.

The ValProbe RT family of data loggers provide accurate, convenient, and reliable process measurement for a wide range of pharmaceutical, and medical device applications. The wireless design greatly simplifies monitoring and validation of severe and hard-to-reach environments. See the table below for logger-types and recommended applications.

Lifting Real Time Validation to the Next Level!

The Kaye ValProbe RT System is a unique design and concept combining a ValProbe RT system with a Validation Console.

The Console is a rugged, hardened tablet to interface with your Kaye ValProbe RT and legacy hardware. It is pre-loaded with all Kaye software and specifically engineered to Validation tasks only. This concept greatly simplifies software validation and dependency on continuously changing PC’s, Operating Systems, and core loads.

The Kaye ValProbe RT is intuitive, efficient, and easy to operate – allowing you to focus on the validation, not the technology.
