Multimeters include non-contact infrared thermometers.

Press Release Summary:




Multimeters incorporate IR thermometers, which provide measurements from -4 to +520°F, and laser pointers. With distance to target ratio of 8:1, units also offer fixed emissivity of 0.95. Extech 450 autoranging DMMs have 2,000 count display and 0.5% basic DCV accuracy, while Extech 470 autoranging True RMS multimeters offer 4,000 count display, 0.3% basic DCV accuracy, capacitance and frequency functions, and Type K thermocouple measurements.



Original Press Release:



Combination MultiMeter + IR Thermometer



Non-contact InfraRed temperature measurements built into Multimeters

Extech Instruments introduces two new ergonomically designed multimeters each with a built-in, non-contact InfraRed (IR) thermometer. The IR thermometer provides fast, easy, and safe measurements ranging from -4F to 520°F (-20 to 270°C) in a wide variety of applications including locations that are unsafe or hard to reach. A built-in laser pointer targets the area being measured. Combining temperature with other advanced multimeter functions provides a highly convenient test tool for diagnosing and trouble shooting electrical distribution systems, electrical circuit connections, motor and pump bearings, and HVAC lines and ducts. The distance to target ratio of 8:1 allows troubleshooting small components on circuit board assemblies. Emissivity is fixed at 0.95 covering nearly all applications for non-contact surface temperature measurements.

The Extech 450 ($99 list) is an autoranging DMM with 2000 count display and 0.5% basic DCV accuracy. The Extech 470 ($129 list) is an autoranging True RMS multimeter with a 4000 count display, 0.3% basic DCV accuracy, capacitance and frequency functions, and Type K thermocouple measurements in addition to its IR capability.

Both models are rated CAT III-600V. Both provide high resolution measurements including 0.1mV resolution for AC/DC voltage and 0.1µA resolution for AC/DC current. Measurements are displayed on a large, backlit LCD with 1" digits that are easy to read even in dim light. Features include MAX and RELATIVE functions, audible and visual input warnings, low current ranges for use with optional current clamp-on adaptors (measure up to 2000 Amps), UL listing, and 3 year warranty. The comfortable design allows for one-hand operation. Complete with CAT III test leads, multi-position tilt stand, Velcro strip for hanging, protective holster with test lead holder, bead wire temperature probe (except Extech 450), and 9V battery. Delivery from stock.
