      calibration-gas-cylindersAll Industrial Scientific calibration gas cylinders are manufactured to the highest quality standards and include NIST traceable blend techniques, analytical leak testing of every cylinder, certified component concentrations and clearly marked lot numbers and expiration dates.

      Replacement calibration gas cylinders are available in a variety of sizes and concentrations for all gases detected by Industrial Scientific gas detectors.

      Industrial Scientific Calibration Kits come equipped with everything you need to keep your gas detectors operating accurately and reliably. Kits contain certified NIST-traceable (National Institute of Standards & Technology) span calibration gases for safe, reliable gas detector calibration.

      Complete kits are available for all installed sensors and include…

      • Convenient carrying case
      • Non-refillable cylinders
      • Flow regulator
      • Regulators

      Regulators provide the proper flow rate for calibrating your Industrial Scientific gas detection instrument. Always make certain to use the appropriate regulator for the application as recommended in the Instruction Manual.
