CALIBRATION GASES AND GAS GENERATORS
GDS Corp Gas Calibration Kits provide a convenient and economical way to maintain optimum
performance from a gas detection system. Available for over 40 different gases and concentrations, each kit contains a cylinder of calibration gas traceable to NIST standards, a fixed flow regulator, tubing, a GDS Corp sensor calibration cup and a convenient carrying case.
Gases include ammonia, carbon dioxide, carbon monoxide, chlorine, chlorine dioxide, hydrogen
sulfide, hydrogen cyanide, isobutylene, methane, propane, oxygen, sulfur dioxide and many more.
The Cal 2000 Calibration Gas Generator provides unmatched versatility and accuracy
for corrosive calibration gases. Field replaceable electrochemical generating cells provide
accurate reference inputs for chlorine, chlorine dioxide, hydrogen, hydrogen cyanide, and
hydrogen sulfide gas sensors.
The Cal 2000 is microprocessor controlled and offers automatic compensation for altitude
and temperature along with field adjustable ppm and flow rate. The gas cells provide up to
50 times as much calibration gas as a disposable cylinder and do not degrade over time.
The Cal 2000 is NIST certified for +/- 10% accuracy.
The CAL 2000 LT is an economical alternative for calibration of corrosive gas detection equipment.
Available in pre-set flow-rates of 0.5 or 1.0 LPM, the CAL 2000 LT can be ordered with cells for chlorine, hydrogen, hydrogen cyanide and hydrogen sulfide in pre-specified concentrations.
The CAL 2000 LT is microprocessor controlled and has an LCD display allowing easy user access
to information such as cell life remaining, battery status, gas concentration and flow-rate. The CAL
2000 LT can be easily upgraded to the CAL 2000.
