Overview

The British Michell Dew Point Meter SF82 is a fast response humidity sensor used to control the dew point and moisture content in compressed air dryers to maximize energy efficiency. The compressor room is usually very hot, with a temperature reaching+50; #176; C （+122 °F）。 Even under these challenging conditions, SF82 can reliably provide as low as -60& #176; Fast and accurate dew point measurement of C (-76&# 176; F) dew point.

SF82 is a fast response dew point meter that can measure the dew point and moisture content in compressed air dryers to maximize energy efficiency. The compressor room typically has a temperature of up to+50 ° C, and even in these challenging environments, SF82 can reliably, quickly, and accurately measure dew points as low as -60 ° Cdp.

The SF82 industrial dew point transmitter adopts PST's new polymer thick film humidity sensor technology, providing fast, stable, and repeatable humidity measurement in all drying machine dew point applications.

SF82 is equipped with a series of process connections and electrical connectors, making installation simple. It also belongs to the service exchange program, which can reduce downtime and maintenance costs.
