Category: Calibration Instruments
Michell provides a sophisticated range of calibration instruments and integrated systems providing traceable calibration of humidity sensors in your own laboratory. Alternatively, send us your instruments for calibration in our advanced calibration laboratory.
DCS - Dew-Point Calibration System
 The DCS is a dew-point calibration system designed for the calibration, verification and characterisation of dew-point sensors, transmitters and instruments. The DCS system is a fully self-contained, calibration station capable of generating reference dew-point temperatures from -100°C to +20°C. Through customisation the DCS system can be PC controlled for automated calibration sequences or manually operated at pre-determined dew-point set points. Product Features
DG Series Humidity Generators
A range of humidity and dew-point generators offering ease of use, fast response for humidity sensor calibration and precise controlled-humidity generation for laboratory process.

HG-1
 The HG-1 is a high precision, portable humidity calibrator. Using Michell’s Optidew Chilled Mirror instrument as the reference measuring instrument, humidity can be controlled across the range 2 to 95% RH (at room ambient operating temperature). The HG1 is configured to operate as a stand alone calibrator or to operate from a dry compressed air supply enabling easy on-site calibrations. The front panel mounted flow-meters enable the mixing ratio of a dry and wet air stream to generate the required humidity. The chamber cover can be customised to suit the transmitters and sensors being calibrated. Product Features

HG-10
 The HG-10 is a completely automatic temperature and humidity calibration system which can be used to calibrate humidity sensors over a wide range of temperatures and humidities. PC control allows start, end values, ramp speeds and dwell times to be selected following which the system automatically tracks the desired humidity/temperature profile and records the measured and reference values. Product Features
Opti-Cal
 Opti-Cal offers the opportunity to provide local calibration of RH sensors that is directly traceable to International Standards over a wide relative humidity range and at any set temperature from 50 to 120ºF. The Opti-Cal is a stand-alone calibrator for RH sensors providing humidity and temperature profiling with a built in, traceable cooled mirror reference hygrometer. The Opti-Cal compliments Michell’s existing humidity generator range and adds the key features of temperature control, traceable reference and fast response. Product Features

Pressure Swing Dryers
 The PSD-Series is designed specifically for calibration applications. It utilises two desiccant columns of molecular sieve and operates on the ‘pressure-swing’ principle. The columns are used alternately and a small quantity of dry air is bled from the in-service column to re-generate the line column. Moisture is absorbed at elevated pressure whilst re-generation occurs at atmospheric pressure, hence the term 'pressure-swing'. The columns are automatically switched on a two minute cycle. The PSD-2 dryer operates continuously and desiccant life is normally in excess of five years. Using oil-free compressed air at 7 barg the PSD-2 delivers up to 10 Nl/min of air at a dew point of better than -75ºC. Product Features
