Advanced Micro Instruments, Inc. (AMI) products

AMI has developed a Class 1, Div. II Group C,D Sample Pump Module suitable for a wide range of previously impossible applications. Our high quality pump uses a unique diaphragm that diffuses less than 0.5ppm of oxygen while drawing from pressures as low as 14”Hg. It pushes the sample gas through the trace oxygen analyzer allowing the sensor to operate at atmospheric pressure. Electrochemical oxygen sensors must operate at or very close to atmospheric pressure for accurate operation.
