Digital, portable dew point measuring instrument for trace humidity measurement
The globally renowned SADP-D, a digital, portable dew point measuring device from Shaw Moisture Meters. It is an easy-to-use hygrometer for fast and reliable measurements of trace moisture in process gases and dry compressed air. It is suitable for a wide range of industries, including power generation, semiconductor manufacturing and pharmaceuticals.
The SADP-D was developed for use in ambient pressure. It has a single on/off switch, an AutoCal potentiometer and a large, easy-to-read LCD display. The measured values can be read either at the °C dew point or at the °F dew point.
The special feature of the SADP-D dew point measuring device is the combination of the unique drying head chamber, the dew point sensor and the AutoCal function. The special construction of the dry head and sensor developed by Shaw Moisture Meters keeps the sensor dry between the measurements. The dew point measuring instrument is always ready for fast spot check measurements of trace humidity.
Check the sensor with the AutoCal function to make sure it is in balance. Unleash the sensor of an atmosphere that is more damp than the operating range, and then adjust the calibration via the potentiometer on the front panel. Perform the AutoCal calibration on site without special training or equipment. This reduces downtime and immediately receives a system check.
Compared to some other methods, there is no need for dials, calibrations, cooling and maintenance. The automatic drying technology ensures that the dew point sensor reacts quickly. The SADP-D dew point measuring instrument is easy to operate: By briefly blocking the spout with one finger, the measuring head rises, which allows a quick measurement of the sample gas or the air.
The SADP-D dew point measuring device is completely independent and safely certified in accordance with ATEX and IECEx standards, which allows use in hazardous environments without additional accessories.
