While Laser IR Thermometers are an extremely common tool, they are entirely ineffective for measuring the outlet temperature of an air heater. To understand why, we must first understand how this tool works. Laser IR Thermometers measure the surface temperature of an object by measuring the thermal energy emitted by the target. Knowing the amount of thermal energy discharged and the emissivity of an object’s surface, the object's temperature can be determined by the device.
When measuring a heater’s output air temperature, the largest issue with these tools is that they measure surface temperatures. As the heated air is transparent, the measurement will always be the surface temperature of a nozzle or a component of the heater housing; and frequently it will be an exterior surface. These items will always be cooler than the heated air, often by a significantly larger margin than the user would expect. To accurately measure the output temperature of an air heater you must measure air temperature and laser IR thermometers are incapable of doing so.
Please note: The indicated welding parameter may vary depending on the ambient temperature and the material configuration. Test welds need to be done and the parameter aligned accordingly!

Electrical certification is a must for any electrical tools bought, sold, or used in Canada. Tools must be tested by an accredited certification organization to determine that they meet the applicable safety standards and adhere to the Canadian Electrical Code. The Standards Council of Canada handles the accreditation of inspection bodies and together with provincial Safety Authorities oversees enforcement.
