Overview
The ValProbe® system uses a wireless probe design that removes the need for hard-wired sensors, simplifying access to hostile, remote or hard-to-reach environments. ValProbe is intended for applications requiring high measurement accuracy and regulatory traceability, including sterilization, pharmaceutical processing and environmental monitoring.

Applications

• Pharmaceutical processing
• Medical device sterilization
• Food processing and HACCP monitoring
• Environmental monitoring
• Saturated-steam sterilizers
• Industrial ovens
• Lyophilizers (freeze dryers)
• Stability and temperature chambers
• Refrigerators and freezers
• Warehouses and cold chain facilities

System Capabilities
Built-in data processing and reporting extend ValProbe functionality beyond raw acquisition. The system calculates results and generates user-defined reports for up to 200 sensors concurrently. Graph reports can combine multiple sensors and configurable limits for straightforward study review. User calibration and on-site verification are supported; CTR-40 Temperature Reference simplifies checks. ValProbe meets FDA 21 CFR Part 11 requirements for electronic records and signatures and complies with ISO-17665, EN285 and HTM-2010 for saturated steam sterilization. A Cryo Logger variant supports applications down to -85°C.
