CAL 101 Calibration Gas Instrument

Gases supported: Cl2 H2 H2S HCN
  • Low cost.
  • Easy to use.
  • Compact hand-held design.
  • 2 hour generating sources.

Our Most Economical

The CAL 101 is our newest and most economical certified calibration gas instrument. Field replaceable calibration gas sources (generating cells) provide immediate calibration gas for Chlorine, Hydrogen Sulfide, Hydrogen and Hydrogen Cyanide.

Safe, Easy, Non-hazardous

The CAL 101 is non-hazardous to ship and will not degrade over time. The electrochemical sources are interchangeable resulting in the ability to calibrate many different types and brands of detectors with one instrument quickly, safely and easily. By simply inserting the appropriate source in the instrument, the user is ready to calibrate.


The CAL 101‘s compact size and light weight provide for safe and easy calibration even for the least accessible detection points. The two “AA” batteries powering the instrument combined with an efficient design provide the user with a light-weight instrument weighing approximately 1 pound or 0.5 Kg.
