The sensors need to physically come into contact with the gas it is designed to monitor. The other type of monitor is the pump monitor. 4-gas monitors like the BW Honeywell Gas Alert Max XT II or the RAE Systems QRAE II have internal pumps that suck air through a tube which can be lowered or pushed into the space workers are going to be entering.

With the new technology the transmitter's inspection interval is extended to five years. Designed for demand controlled ventilation, these transmitters measure carbon dioxide and temperature, with the option for humidity measurements. The instruments come with a calibration certificate that meets traceability and compliance requirements.

Natural gas is less dense than propane. In many cases, a home piped for propane may need to be re-piped with larger lines for natural gas. Generally, propane distribution lines have only a half-inch inside diameter, but natural gas lines need to have at least a 3/4 inch inside diameter to deliver an equivalent amount of natural gas.

RKI's FP-31 is a formaldehyde gas detector which uses a photoelectric photometry method utilizing colorimetric tablets for detection. To sample a tablet is placed into the system and and room air pumped onto the tablet for 15 or 30 minutes, staining the tablet in magnitude relative to level of formaldehyde detected in the air.

A mixing ration of 10 ppb of formaldehyde in the gas phase leads to 10 −6 mol L −1 solution at the exit of the stripping coil, assuming all molecules of the water-soluble gas are transferred into the liquid phase. The collection efficiency was measured with two instruments in series.
