Performance & Reliability

Gas Detectors require regular tests and calibration to ensure they accurately detect gas. These detectors measure gas in the low Part Per Million (PPM) and Part Per Billion (PPB) range.  As a sensor ages, it loses sensitivity. Exposure to gases and other environmental factors can cause a gas sensor to deteriorate.  Calibration adjusts the detector's sensitivity to compensate for changes in the sensor.  Safety Instruments uses gas mixtures that are NIST Weight Traceable.  When requested, we will provide a calibration certificate for each gas detector we service. In addition to calibrating, we test each detector to ensure they meet all manufacturer performance specifications, as outlined in the manufacturer's owner manual.

Decrease Downtime and Repair Costs

Safety Instruments factory trained service technicians, test and calibrate a variety of fixed air monitoring and gas detection systems. Due to the high sensitivity of these systems, quarterly calibration and test is recommended, to ensure the equipment is kept in good working order.  Safety Instruments uses NIST weight traceable calibration gas to calibrate the equipment. A service report is supplied after each service visit. The service report details the test and calibration data. A calibration label is placed on the system that indicates; date of service, next due date, gas standards used and the technician’s name. A functional test of remote alarms and interfaces is performed at customer requested intervals.

ANSI-ISA ISA-RP92.0.02, Part II-1998 (R2013) States “It is important that the Checkout Procedures (refer to Clause 10) be performed by qualified personnel trained in the operation, maintenance, and repair of toxic gas detection instruments, and that the personnel responsible for maintenance be defined clearly.”


ANSI-ISA-RP12.13.02 (IEC 61779-6 Mod): States “Maintenance procedures should be undertaken only by personnel trained in the operation, maintenance and repair of flammable gas detection instruments.”
