HF5 Series Temperature & Humidity Transmitters

Quick Overview

The new Hygroflex 5 Series offers the ultimate in performance and flexibility due to its interchangeable hygroclip 2 probes. The HF5 series offers a unique calibration and adjustment process and the ability to interchange probes in just a few seconds. System accuracy is 0.8% RH and 0.1 K. The transmitters come in various configurations and the optional software allows digital versions to be networked together to form a dedicated environmental monitoring system.
