Hand-Held Gas Sampling Pump
The hand-held pump rotation when the pump work, to test gas inhaled from the suction port, through the exhaust vent to the test instrument (sensor) tested on the test hole
Hand-Held Gas Sampling Pump
I.Product Features and Purpose
1. Product features
This product is characterized by no pollution transmission and maintenance free. The dust filter with high precision installed in suction hole prevents the blocking of gas pump caused by the absorption of impurities, such as, flying dust in air, foreign particles, etc., and the influence on flow of gas sampling. The installation can be conducted in any direction; there can be vapor in the medium and the flow of gas absorbed is stable. It is featured with small volume and low energy consumption.
2. Purpose: It is mainly applied in cooperation with portable test instrument for gas sampling, including the test instrument of Carbon Monoxide, Carbon Dioxide, Ozone, Ammonia, Hydrogen Sulfide, Hydrogen, Formaldehyde and others.
