Honeywell Piston Hand Pump Configuration:Handpump only The glasses feature vented templesThe Honeywell LP 1200 Piston Hand Pump is used to pull a fixed volume of air through the Honeywell colorimetric gas detection tubes.

Tubes are made to measure a specific combination of gas and concentration, and are generally thought to be accurate within 25 percent
