Honeywell Piston Hand Pump Configuration:Handpump only These mats are designed toThe Honeywell LP 1200 Piston Hand Pump is used to pull a fixed volume of air through the Honeywell colorimetric gas detection tubes. This air sample then reacts with the granulated chemicals contained within the tubes. This reaction produces a visual color change which is measured against the scale printed on the tube. Tubes are made to measure a specific combination of gas and concentration, and are generally thought to be accurate within 25 percent
