15% Carbon Dioxide (CO2), 15% Methane (CH4) Calibration Gas

Our landfill gas meter calibration gas consists of 15% methane (CH4) and 15% carbon dioxide (CO2).  The calibration gas is typically used for calibrating landfill gas meters such as the Landtec GEM 2000 and GEM 5000.  The calibration gas is NIST traceable and comes with a certificate.

1/8" x 1/4" LDPE Tubing

1/8" x 1/4" Low Density Polyethylene Tubing is typically used as down-well peristaltic pump tubing.

1/8" x 1/4" Teflon FEP Tubing

1/8" x 1/4" Teflon® Fluorinated Ethylene Propylene (FEP) Tubing

1/8 in. Braided Nylon Rope

1/8" Braided Nylon Rope for lowering groundwater bailers into monitoring wells to collect a sample.

2000 ppm Methane (CH4) Calibration Gas

Our 2000 ppm methane calibration gas is NIST traceable and includes a certificate. The gas is typically used for calibrating flame ionization detectors (FIDs) and other volatile organic compound detectors.

3/16" x 1/4" Teflon® FEP Tubing

3/16" x 1/4" Teflon® Fluorinated Ethylene Propylene (FEP) Tubing

3/16" x 3/8" Silicone Tubing

3/16" x 3/8" Silicone Tubing, typically used for peristaltic pump head operation.

35% Carbon Dioxide (CO2), 50% Methane (CH4) Calibration Gas

Our landfill gas meter calibration gas consists of 50% methane (CH4) and 35% carbon dioxide (CO2).  The calibration gas is typically used for calibrating landfill gas meters such as the Landtec GEM 2000 and GEM 5000.  The calibration gas is NIST traceable and comes with a certificate.

3/8" x 1/2" HDPE Tubing

3/8" x 1/2" High Density Polyethylene Tubing is typically used with intertial pumps such as the Waterra Hydrolift 2.  The high density nature of the tubing minimizes stretching.

3/8" x 1/2" LDPE Tubing

3/8" x 1/2" Low Density Polyethylene Tubing is typically used with submersible groundwater pumps.

3/8" x 1/2" Teflon Lined Poly Tubing

3/8" x 1/2" Teflon® Lined (0.015" Liner) Polyethylene Tubing

3/8" x 5/8" Silicone Tubing

3/8" x 5/8" Silicone Tubing (per foot)

3/8" x 7/16" Teflon FEP Tubing

3/8" x 7/16" Teflon® Fluorinated Ethylene Propylene (FEP) Tubing

pH 4 Buffer Solution

pH 4 Buffer solution for calibrating water quality instruments.

4% Oxygen (O2) Calibration Gas

Our 4% oxygen (O2) calibration gas is NIST traceable and includes a certificate.  The gas is typically used for calibrating landfill gas monitors.

4-Gas Calibration Kit Rental

**NOTE: Calibration Kit Rentals are only available for PICKUP, gas must be purchased if the items need to be shipped.**

All of our gas monitor rentals are calibrated before they are sent to you.  However, sometimes you are required to do your own calibrations in the field.

The 4-Gas Calibration Kit Rental is used to perform field calibrations on Multi-Gas Detection Monitors.

Includes:

  • Cal Gas: 10 ppm hydrogen sulfide (H2S), 50 ppm carbon monoxide (CO), 50% LEL methane (2.5% CH4), 18% oxygen (O2)
  • Calibration Gas Regulator
Starting at $20 Daily
4-Gas Mixture (50% LEL CH4, 50 ppm CO, 10 ppm H2S, 18% O2)

Our four gas calibration mixture consists of 50% LEL methane, 50 ppm carbon monoxide, 10 ppm hydrogen sulfide, and 18% oxygen.  The four gas calibration mixture is typically used for calibrating multi-gas meters for confined space entry.  It is NIST traceable and comes with a certificate.

4-Gas / PID Calibration Kit Rental
