Product Overview
Kaye ValProbe® RM is a real-time wireless datalogger system developed for temperature mapping and thermal validation applications in pharmaceutical, biotechnology, and other GxP-regulated industries. The platform combines wireless data loggers, interchangeable digital sensors, and centralized software integration within a unified validation environment.

ValProbe RM and RM-B Logger
The ValProbe RM and RM-B are wireless, battery-powered data loggers engineered for accurate and reliable thermal validation and temperature mapping applications in GxP-regulated environments. Both logger variants support interchangeable digital sensor modules and secure real-time data acquisition while maintaining local onboard storage for redundancy.

Flexible Digital Sensors
The ValProbe RM platform supports interchangeable digital sensor modules for temperature, humidity, and other validation measurement applications. Each wireless datalogger includes dual sensor ports for flexible sensor configuration. Calibration data is stored directly within each digital sensor module, allowing sensor replacement without recalibrating the logger and preserving traceability. The system automatically recognizes sensor changes and supports electronic signature verification to maintain traceability and validation compliance.

Real-Time Wireless Architecture
The ValProbe RM platform utilizes a proprietary dual-antenna RF architecture operating on a 2.4 GHz wireless network. The scalable star-network architecture supports stable real-time data transmission across large validation areas and is designed to reduce communication interruptions in complex industrial environments. Each base station supports up to 50 wireless data loggers with communication ranges reaching approximately 300 meters (900 ft) line-of-sight. Multiple base stations can be integrated through Ethernet connectivity for expanded deployment flexibility. The RF architecture incorporates AES 128 encrypted communication and local data buffering; automatic reconnection capabilities help maintain study continuity during temporary connectivity interruptions.

Data Integrity and Redundancy
The ValProbe RM thermal validation system is designed to support secure data handling and uninterrupted data retention throughout qualification and mapping studies. Each wireless datalogger stores up to 100,000 samples per sensor within non-volatile memory to protect recorded data during battery replacement, temporary power interruptions, or network disruptions. The platform incorporates AES 128 encrypted communication, local data buffering, electronic signature support, and full audit trail capability to support GxP data integrity requirements. Configurable user authentication controls, tamper-resistant data management, and automatic sensor recognition with traceability features are included. When operating with external power, the system can transition to battery backup during power failures to maintain continuous data collection and gateway-level buffering with automatic reconnection further protects studies.
