CAL 2000LT Calibration Gas Instrument

The Cal 2000 is CSA, ATEX and CE certified Gases supported: Cl2 H2 HCN H2S
  • Mass flow feedback and source monitoring provide our highest level of accuracy.
  • 10 and 25 hour sources available
  • English, French, German and Spanish user interfaces are available.
  • CSA certified and intrinsically safe.

Accuracy, Wide Range of Gases

The CAL 2000 LT is the certified calibration gas instrument of choice for the user who does not need variable flow rates or concentrations, and is available in pre-set flow-rates of 0.5 or 1.0 PPM.

Field replaceable calibration gas sources (generating cells) provide a calibration standard for accurately testing Chlorine, Hydrogen, Hydrogen Cyanide, and Hydrogen Sulfide gas detectors with a single instrument.

Calibration gas sources (generating cells) are rated at ten or twenty-five hours over a range of 1 to 25 PPM in whole PPM increments. To change gas type or concentration simply insert a different source into the instrument.

Easy to Use

The CAL 2000 LT is microprocessor controlled and has an LCD display allowing easy user access to information such as source life is remaining as well as battery status, gas concentration and flow-rate. The sources are interchangeable and field replaceable and come with a one year warranty.

NIST Certified

The CAL 2000 LT calibration gas instrument has a built-in mass flow sensor that automatically compensates for altitude and temperature resulting in accurate cal gas everywhere you use it. Both the CAL 2000 LT instrument and the sources are NIST certified + 5% accurate for one year. Instruments and sources can be re-certified at the ACD factory. Best of all, each source provides up to 25 cylinders worth of gas at a fraction of the cost.

Calibration Gas Sources

10 and 25 hour sources are available.
