It is vital to worker safety that these instruments are maintained and calibrated properly. Instrument inaccuracy due to improper or irregular calibration can lead to serious accidents. Exposure to excessive levels of toxic gas or an oxygen-deficient environment can cause workers serious illness and even death. Combustible gas explosions are often catastrophic, injuring or killing personnel and destroying property. The only way to guarantee that an instrument will detect gas accurately and reliably is to test it with a known concentration of gas. Exposing the instrument to a known concentration of test gas will show whether the sensors respond accurately and whether the instrument alarms function properly. DEFINITION: QUICK CHECK The brief exposure of the monitor to gas at concentrations higher than those of the low-alarm set-points to test the functionality of the monitor.

The instrument reading is then compared against the reference point of the last calibration and if it is within an acceptable range (normally 10%) its calibration can be considered accurate. 10 Litre Hydrogen Sulfide Air or Nitrogen 6 Months DEFINITION: CALIBRATION Calibration refers to an instrument s measuring accuracy relative to a known concentration of gas. Gas detectors measure the concentration of a gas in an air sample by comparing the sensor s response to the response generated by a calibration gas of a known concentration. The instrument s response to the calibration gas serves as the measurement scale or reference point. 100 www.conceptcontrols.com
