ΔThese gases require the Sampling Shield p/n
Sensor response time with internal pump, if the tubing is 20 feet long, allow at least 10 seconds for the test sample to make it through the tubing. The sensor response time is typically 30 – 60 seconds to achieve 90% o f the final reading, depending on the specific sensor and the gas being detected. Therefore, the total 'system' response time for an instrument using the internal sampling pump and 20 feet of hose is approximately
