Determining the efficiency of an HVAC system is often tedious and time consuming. Today, infrared (IR) thermometers offer a faster, more effective way to diagnose duct leaks, blocked steam traps, wet insulation, malfunctioning coils and or other heat-related problems common to HVAC systems.
The ST8810 thermometer from PREI Instrumentation has a laser light for aiming, and covers the range of -20 to 270°C with an accuracy of 2% or 2°C. Other instruments in this series can measure down to -50°C and up to 500°C.
IR devices take the surface temperature of objects without touching them by measuring the IR energy emitted from the target. Although this technique has been around for many years, advances in IR measurements technology have only recently allowed the development of lightweight, low-cost tools for monitoring processes and speeding up plant maintenance. Modern IR thermometers are used in scores of industries, whenever temperature is of significance.
