Temperature data-logger ValProbe RT 5-Channel

wirelessradio frequencyfor ovens

Overview
ValProbe RT loggers with bendable sensors cover a wide temperature range from -85°C to +400°C. They are offered in single-, dual- and five-channel bendable-sensor versions. Precision platinum RTD sensing provides high measurement accuracy while the logger electronics are designed for extended battery life. Operator-programmable sample rates start at 1 second and each sensor can store up to 100,000 data points. Antenna diversity ensures robust RF communication reliability.
