Pressure data-logger ValProbe RT

temperaturehumidityfor freezer

Overview
The Kaye ValProbe RT real-time temperature data loggers are available with flexible, Teflon™-coated sensor cables in single-, dual- and 5-channel configurations. Each sensor stores up to 100,000 data points in non-volatile memory. The flexible sensor cable is 1 m (40") long and terminates in a stainless-steel tip protecting the precision platinum RTD element. Operating range: -85°C to +140°C. These loggers are designed for validation and monitoring tasks in pharmaceutical and GxP environments.

Key benefits

• Multiple sensor configurations (single, dual, 5-channel) for point or multi-point monitoring.
• Large on-board storage: 100,000 samples per sensor retained in non-volatile memory.
• Long, flexible Teflon™-coated cable (1 m / 40") and compact stainless-steel tip for penetration and confined-space measurements.
• Precision RTD sensing with high accuracy across a wide temperature range suitable for validation tasks.
