  • Page 1 SHAW AUTOMATIC DEWPOINT METER MANUAL July 2004 INSTRUCTION MANUAL FOR MODELS SADP, SADP-TR & SADP-D For information about: See page: AUTOMATIC CALIBRATION BASIC DEFINITIONS BATTERIES BATTERY CHECK BATTERY REPLACEMENT CABINET CALIBRATION CHECKING CERTIFICATION 19-22 CARRYING CASE CONTINUOUS READINGS CONTROLS DESCRIPTION...
  • Page 2 July 2004 MODELS: SADP, SADP-TR & SADP-D The SADP & SADP-TR are a battery operated portable unit designed for spot checks or continuous use, and gives direct indication in dewpoint temperature and parts per million on a 12cm analogue scale, SADP-D versions perform the same function but display only Dewpoint on a LCD display.
  • Page 3 CONTROLS SADP instruments have a single rotary switch to the right of the indicator, which controls the power supply, the battery check and the range selection (in dual range models) . The switch positions are marked on the instrument fascia. SADP-D models have a single on/off switch...
  • Page 4 SHAW AUTOMATIC DEWPOINT METER MANUAL July 2004 OPERATION Brief operating instructions will be found on the label fastened to the top of the instrument cabinet. The standard test procedure is as follows: Switch the instrument on, and check the battery condition.
  • Page 5 This means, for example, that the Yellow Spot sensor used in the Model SADP-Y for the range -60 to 0 C dewpoint will read 0 deg C when exposed to gas at 0 deg C dewpoint, but will continue to read 0 deg C dewpoint when it is exposed to wetter gas.
  • Page 6 The Shaw High Capacitance Sensor has been undergoing continuous development since it was invented by Mr. J. L. Shaw in the late 1940’s. Protected by world patents the sensor is manufactured by a unique automated process, which results in a long life device with fast response, high accuracy and good stability.
  • Page 7 The response time of any water vapour pressure detector will naturally be very much quicker from dry to wet, than from wet to dry. This is the reason that the Shaw Automatic Dewpoint Meter is so successful: the sensor is kept in a dry condition when it is not in use, and therefore results are obtained in the quickest possible time.
  • Page 8 GUARANTEE All Shaw products are guaranteed conditionally for a period of two years from purchase, exceptions being accidental damage, or damage caused by misuse or abuse. This period may be reduced to one year if the instrument is purchased from the stock of one of our overseas dealers.
  • Page 9 July 2004 IMPORTANT Shaw sensors are suitable for many different industrial research applications Most gases can be checked for their moisture content, and there is no need for the calibration to be altered when changing between different gases - even such different gases as Carbon Dioxide and Hydrogen: the sensor operates only with reference to the water vapour content.
