Michell DryCheck dew point instrument and sampling system

Click2Contact

The DryCheck from Michell is an accurate and stable dew point instrument, which includes a built-in simple sampling system. Its compact size allows the instrument to be easily installed in a number of dew point measurement applications, such as compressed air dryers, ozone generators, plastic moulding machines and industrial gas manufacture. Designed for quick and easy maintenance, the DryCheck is a good choice where ease of use and simple installation are important.

All components are housed in a rugged IP65-rated polycarbonate case. This can be wall mounted at a convenient point close to the gas sample. A clear cover protects the display and the sample flow meter. Gas connection (gas in and gas out) is provided using ‘quick-connect’ push fittings, suitable for use with 6 mm OD Teflon tubing. Mains power input, and connection to the 4-20 mA analog output, and the two user-programmable, voltage-free relay contacts are all easily accessible behind the lower panel.

The device uses the Michell Instruments Easidew On-Line to measure dew point in the range -100 to + 20°C dew point, or moisture content in the range 0-3000 ppm. The sampling system includes a 0.3 micron particulate filter element, a monolithic sampling block to house the Easidew transmitter, as well as a valve and flow meter for setting the sample flow.

The device features a clear 20 mm red LED display, which can be programmed to display dew point, in C or F or moisture content in ppm_V.
