PORTABLE DEW POINT METER- HLS-PDP

The Hemaki Model HLS-PDP Dew point Meter is portable and measures

Dew point of water vapour in dry air or gas cylinder and digitally displays the dew  point deg, C in the range -100°C dp to +20°C

 

The HLS-PDP can be powered by 110 Or 230 v.a.c 50 Hz OR chargeable battery. The HLS- PDP has an on /off switch on the front panel Digital Display in °C DP 

The dew point sensor is of high capacitance aluminium oxide
The desiccant dryer keeps the sensor dry for quick response to low ppm.
This model can not be used for immflamable gases like H2, CH4, CNG etc

This model can be used for following application

Process gas monitoring, Quality assurance, R & D applications, pure gas like N2, Ar, O2, CO2, He etc. and glove boxes. Ultra high purity gas moisture measurement.

Spot checking, cylinder filling plant. Transformers, switch-gears and dry vessels.

We offer the high precision and reliable Dew point meter /Moisture meter. It is used to measure the amount of moisture in air or gas samples, within the range of +20oC to -110oC dew point i.e. 23,000 ppm down to nearly 1 ppm. The product is basically a product of Shaw Moisture Sensors that has 1000 times’ dry capacitance as compared to other similar products. It requires only the room air for unique Automatic Calibration, which is done in seconds by our clients. The product detects moisture in almost every non-toxic gas such as Argon, CO2, He, H2, Natural Gas, O2, SF6, N2 and Air. However, it is not suitable for toxic gases.

¨          In the interest of continued product we reserve the right to change the specification without prior notice

 We have developed a combined analyzer Model-OMPM-DP suitable for cylinder-filling plants (with some customer’s feedback at our stall in  AIIGMA conference Malaysia),

Special Features

§  1) This has two analyzers combined in one cabinet. One analyzer gives Oxygen( with option of %     range 100% to .01% or  ppm level-2000ppm to 0.1ppm ), and second gives moisture in Dew-point- range- -100 to +20dpC with 0.1C resolution.  with converter reading in PPm (V)

 

2) Both analyzers are internally connected, so that there is only one input line to be connected.

3) When the analyzer to be switched from one cylinder to next, both the sensors can be bypassed so that no outside air enters the sensor compartment. Hence the analyzer response is fast for the next cylinder reading.

4) This bypass arrangement also increases life of the sensors as it’s not exposed to air contamination. 5) This analyzer is easy to use by unskilled work force.

6) Both internal analyzers can be calibrated with standard room air.
