RF ValProbe II Loggers – Wireless Data Logger

The Kaye RF ValProbe II wireless data logger integrates RF mesh technology to get wireless, high-accuracy measurements of temperature & humidity in a warehouse or facility.

Simplified Real Time Validation

Wireless High accuracy measurement of temperature and humidity

The Kaye RF ValProbe II wireless data logger integrates breakthrough RF Mesh technology with enhanced technology for Thermal Validation. The operating range of the loggers of -40°C to +60°C and temperature sensor range of -200°C to +200°C make them ideal for real-time RF validation and monitoring of environmental chambers, warehouses, freezers, refrigerators and steam-in-place (SIP) applications.

The wireless data logger system utilizes a 2.4 GHz RF Mesh network and multiple redundant data storage to provide ultra- reliable and robust communications and storage of critical validation data. Additional safeguards guarantee data integrity, storage and compliance with regulatory requirements.

The ValProbe RT system combines high accuracy measurements, automated sensor verification, an intuitive metro style user interface, and extensive reporting to simplify the complete validation process.

Take the next step and see how the Kaye ValProbe® RT wireless thermal validation system greatly simplifies monitoring and validation of severe and hard-to-reach environments while also providing validation efficiency and time savings.

Common Reporting Tool Software

Sometimes the reporting and post analysis of your validation studies are better done in the convenience of your office on a separate PC. That is possible with the Kaye Common Reporting Tool that opens study files generated with Kaye ValProbe RT and Kaye Validator AVS systems. This provides added flexibility and efficiency with the use of your Validation Console. The installation requires Windows 10 with English (US) settings and keyboard.

Kaye Builds Extension to China Calibration Laboratory, Enhances Equipment

After receiving the ISO 17025 Accreditation earlier this year Kaye is further investing into the China Service Center of Excellence by building out the China calibration laboratory, located in Changzhou, Jiangsu.

Kaye’s China lab has recently undergone a renovation, which included expanding the calibration space and adding new equipment. This renovation adds calibration baths and validation equipment to the top-of-the-line laboratory to enhance the quantity and types of instruments the lab can handle.

“Expanding out laboratory has been great for our team and will also be great for customers,” says Xiqing Wu, Kaye China (Taiwan & Hong Kong) Sales Manager. “Not only does it show the growth within Kaye, but also shows that we’re dedicated to having the best equipment possible to provide our customers will the best instruments for their applications.”

The expansion included acquiring a new autoclave that will be used when calibrating and verifying customers’ Validator AVS, ValProbe RT and ValProbe loggers.

“This allows us to imitate the same application that our customers perform in their factory, for instance, 121°C sterilization,” says Wu. “Also, we can show our new customer how to do the sterilization validation in real process during customer training in our lab.”

Kaye has long believed in keeping customers informed and aware of what type of calibrations we do on the equipment they have purchased. Customers oftentimes enter the calibration lab to receive training on their new Kaye products and also view what sort of tests their equipment is put through in order to achieve maximum accuracy. With so many customers entering the lab for training purposes, this expansion provides ample room for groups of customers to arrive and stay safe while on-site.

The expansion also gave some of our products their own dedicated space for calibration, including our IRTDs, ValProbes, HTR dry blocks, and LTR calibrators. This allows faster turnaround time for calibration, meaning customers will get their equipment back in a more timely fashion.

As the world leader in validation and calibration, Kaye is proud to see such growth within our engineers, facilities, and equipment, and looks forward to continuing toward serving our customers in the pharmaceutical and biotech industries.
