Product Files

Features

•  Analogue or Digital Display

•  Intrinsically Safe for use in Hazardous Areas

•  Automatic Calibration

•  Desiccant Dry-Down Chamber for rapid measurements

•  Over 150 hours continuous operation

•  Self Contained and fully portable

•  Simple to operate

Having been in production for nearly 50 years, this unit has stood the test of time and it's popularity is demonstrated by the fact that it can be found in every industrialised country in the world. It remains the benchmark in portable hygrometry for measuring absolute humidities down to one part per million and below.

Built to the exacting demands stipulated by SHAW, the robust and easy to use Model SADP Dewpoint Hygrometer has, at its heart, the world renown SHAW High Capacitance Sensor with the unique Automatic Calibration feature (see overleaf).

Designed to operate at atmospheric pressure, the instrument is available in a variety of sensor ranges, covering an overall range of -110°C to +20°C dewpoint.

Shaw Gold Filter High Capacitance
Moisture Sensors with 20 year life
Purple Spot -100/0 degrees c. dew point. 0/6000 p.p.m.
Silver Spot -120/-20 degrees. c. dew point.
Red Spot DP -80/-20 degrees c. dew point. For SADPR
Red Spot Auto -80/-20 degrees c. dew point.
Grey Spot -80/0 degrees c. dew point .

Analogue versions of the SHAW Automatic Dewpoint Meter offer the 0-10ppm(v) range expanded over the full scale, which is selected by means of a rotary switch on the front panel. This allows for accurate measurements below 10ppm(v).

Digital versions of Model SADP can be configured to display dewpoint in either °C or °F on a large, easy to read, 41/2  digit LCD display.

The SHAW Automatic Dewpoint Meter is fully self-contained and is also certified as intrinsically safe for use in hazardous areas, without the need for any additional accessories such as zener barriers etc.

The unit is supplied ready for use with batteries installed and a calibration certificate traceable to National and international standards. Standard accessories supplied with the unit include a specially designed carrying case with shoulder strap, operational tools, 2m PTFE sampling hose and a pressure dewpoint calculator.
