Calibrates and verifies the performance of heat stress monitors using best practice metrology methods. Our procedures are designed to maximize the accuracy, repeatability, and reproducibility of your heat stress monitor. Heat stress monitors can be sent to CIH Equipment for calibration to NIST standards. A Certificate of Instrument Calibration will be issued only if the heat stress monitor, along with all three of its sensors, have passed calibration. Annual calibration is recommended.
A heat stress monitor comprised of a thermometer tube having at least a black globe-bulb and a wet-bulb therein and adapted to provide a direct reading of wet-bulb globe temperature (WBGT). The inclusion in the tube of a dry-bulb makes the monitor particularly adapted to measuring WBGT outdoors. The thermometer tube is in the form of a single tube and the bulbs are disposed in series therein with an extension part extending beyond the bulbs to permit a direct reading to be taken of the position of a thermally responsive medium in the tube.
At CIH, we follow NIST traceable standards. Our trained technicians take a very thorough and detailed approach to servicing and calibrating your heat stress monitor. We're as concerned for worker safety as you are.A functional test is the initial step in diagnosing the current condition of the heat stress monitor. An instrument calibration, involving testing sensors by an NIST traceable standard, to ensure the unit is functioning and reacting based on a set of guidelines in accordance manufactures standards.
