Temperature data-logger RF ValProbe® II

low-temperaturehumidityuniversal

Description
The Kaye RF ValProbe II wireless data logger combines a 2.4 GHz RF Mesh network with redundant local and base‑station storage to support thermal validation and continuous environmental monitoring. Logger ambient range: -40°C to +60°C; external probe range: -196°C to +200°C. Suitable for real‑time RF validation and monitoring in environmental chambers, warehouses, freezers, refrigerators and Steam‑in‑Place (SIP) systems.

System overview
The system comprises RF wireless data loggers, a base station and management software. Loggers measure temperature, relative humidity and auxiliary signals (4–20 mA, 0–10 V, dry contact). The base station gathers and stores data while the software provides self‑configuring mesh networking, automatic data collection and regulatory‑compliant reporting.

Key features

• 2.4 GHz RF Mesh networking for reliable real‑time process data
• Redundant storage: local logger + base station; optional microSD and USB backups
• Integrated LCD, industrial enclosure and compact logger size (110 x 65 x 30 mm)
• Dual power: mains or battery; typical logger battery life ≈ 1 year at 1 min sample rate
• Support for 2‑channel and 5‑channel temperature loggers and multiple sensor types
• External RH probe extension up to 3 m; SmartGasket® compatibility for 1.5" tri‑clover connections
• Meets temperature and pressure accuracy requirements referenced in ISO‑17665, EN554 and EN285
• Advanced software tools for graphing, cycle/group reporting and merged reports across Kaye products

Applications

• Environmental chambers
• Warehouses and cold storage
• Freezers and refrigerators
• Steam‑in‑Place (SIP) systems and sterilizers
