Convenient Source Of Positive Pressure For Spot Checking
This unit is a portable configuration of the high-quality pump offered by AMI. It is designed for use with the MODEL 1000RS Portable Trace Oxygen Analyzer and creates positive upstream pressure to push sample gas through the Analyzer. Its unique diaphragm can draw pressures from as low as 14” Hg, and its tubing material prevents oxygen amounts over 0.05 ppm from diffusing into the system. This not only ensures that oxygen levels are not artificially elevated, but it still allows the sensor to continue operating at atmospheric pressure – a requirement for proper functioning of an electrochemical sensor. The unit utilizes a 12VDC brushless motor to withdraw sample from low pressure or vacuum gas lines and has approval for operation in Class 1, Div. II Group C,D environments.
