General Tools & Instruments: Gun-Style Infrared Thermometer
May 7, 2012
Easily and accurately measuring surface temperatures — including hot, cold, or inaccessible equipment — is the 12:1 point-and-shoot, gun-style wide-range infrared thermometer IRT657. With its broad measurement range of -40° to 1,076°F (-40° to 580°C), the thermometer is perfect for testing and troubleshooting HVACR systems and components, said the company, including for monitoring food processing and storage temperatures; checking heating, a/c, and refrigeration system components; taking the temperature of forced hot-air supply and return vents; testing chillers, steam traps and heat exchangers; and energy auditing. The IRT657 features accuracy of ±3°F (2°C) above 32° (0°) and ±5° (3°) below 32° (0°), and a 12:1 distance-to-spot ratio. The instrument has a response time of 250 milliseconds, fixed emissivity of 0.95, and a handy front-panel °F/°C selection switch. It comes with a carrying case and a user’s manual.
