RAE Systems Colormetric Pump

The RAE Systems LP-1200 Piston Pump can be rented the next time you need to sample with RAE colorimetric tubes. Select and order your tubes from the download sheet. Tubes can be ordered in boxes of ten tubes per box. For your convenience we have included a second download with instructions on operation.

RAE Systems Detector Tubes are available for various chemical compounds.
All tubes sale at $48.00 per box.

Piston Pump Components

RAE Systems piston pumps are easy to maintain and operate. Components of the pump include the inlet and inlet nut where the colorimetric tube is inserted, the pump shaft and reservoir cover, which includes a convenient tube tip breaker, and the plunger handle. The pump is clearly marked to ensure proper alignment of the shaft and plunger. Before obtaining a sample, always perform a basic piston pump inspection to ensure all parts are undamaged and working properly.

Checking for Leaks

A leaking pump will seriously compromise your ability to take an accurate reading. Checking for leaks is an important part of any preliminary piston pump inspection. Simply follow these steps to be sure your unit is working properly:

  • Place an unbroken tube into the pump inlet.
  • Pull the plunger all the way back (one full stroke), and wait two minutes.
  • Turn the alignment marking on the plunger handle away from the corresponding dot on the pump shaft; this will cause the plunger to be pulled back into the shaft.
  • If the pump is leak-free, the plunger will return back to within 3 mm of its original position.

Obtaining a Reading

To obtain a reading of piston pump sample materials, break the tip off an air sample tube and place it into the inlet. Align the red dots on the plunger and pump shaft to prepare for sample collection. Then, consult the directions printed on the side of the gas detection tube and perform the indicated amount of strokes, turning the handle a ¼ turn to repeat as necessary.

You can obtain a reading from the scale printed on the gas detection tube. Look for the furthest distance along the scale that a color change is visible. Be sure to check the tube immediately after obtaining the piston pump sample, as the color change will become less evident with time. Apply correction factors for temperature and humidity as outlined in the gas detection tube’s data sheet.

Available Gas Detection Tubes

Over 30 different detection tubes are available for use with RAE Systems piston pumps. Gas detection tubes are available for VOCs such as acetone, benzene, formaldehyde and toluene, as well as carbon monoxide, ammonia and more. For many compounds, a single tube can provide readings in a number of different ranges.
