Special Design to achieve Highest Accuracy for Surface Temperature Measurement 


The X2534 ValProbe surface temperature logger design provides enhanced and precision wireless measurement capability ideal for freeze dryer shelf temperature measurement over an extended temperature range from -85°C to +140°C.

The embedded RTD technology is integrated into a unique compact surface design, delivering unrivaled measurement accuracy, stability, and response time over the full temperature range. In addition, the Freeze Dryer Logger has been designed to minimize power consumption to deliver maximum battery performance in extremely cold environments.

The new surface Logger is compatible with the existing ValProbe family of Loggers, Readers and software. It is designed for easy on-site user verification between studies with the traditional IRTD and the low temperature CTR-80 bath. Using the standard Kaye Report Wizard, Validation engineers are guaranteed consistent reports among all Kaye products with the capability to merge study data with a Kaye Validator or the RF ValProbe. The surface Logger and Report Wizard offer added value when performing validation execution, saving time and money.

The ValProbe system satisfies FDA Regulation 21 CFR Part 11 requirements for electronic signatures, and records and complies with DIN ISO 17665 for saturated steam sterilization and is used to fulfill GMP requirements.
