EXTECH IR320 Dual Laser Infrared Thermometer

12:1 Waterproof IR Thermometer with High/Low Alarm

Rugged design with Waterproof (IP65) and 9.8ft (3m) drop-proof protection, Extech IR320 provides fast and accurate temperature measurements up to 650°C.

The IR320 dual guided laser shows the target area between the two points at a 12:1 distance to target ratio.

It has programmable High and Low Alarms with Red (HI) and Blue (LOW) visual LED alert. The Lock function allows for continuous measurement.

Description

The EXTECH IR320 Dual Laser Infrared Thermometer is designed to tackle tough jobs indoors and out. The IR320 is designed for electrical contractors and plant maintenance technicians who face an array of temperature diagnostic challenges from overheating motors and pumps, to corroded electrical connections, failed steam traps, premature wear on processing equipment, as well as faulty HVAC and refrigeration systems.

The Extech IR320 survives falls off a ladder from heights up to nearly 10 feet (3m). With an ingress protection rating of IP65, the meter is dustproof and easily handles wet environments, from rainy outdoors to water-intensive manufacturing processes.

For improved accuracy, the IR320 features two laser pointers to visually show a 25mm measurement spot at the optimal 30.48cm distance. The 12:1 distance to spot ratio adds a layer of safety for technicians by permitting non-contact temperature readings at a safe distance from dangerous energized or moving equipment. To expand its testing versatility across a much wider range of plant and electrical equipment, Extech added a higher temperature range spanning to 650°C and adjustable emissivity for different surfaces.

To make it easier to scan equipment at job sites for trouble, maintenance professionals can set up high and low alarm thresholds to trigger when abnormal conditions are detected. The IR320’s innovative alert system flashes a bright blue LED for low temperature alarms and a red LED for high temperature alarms. The fast-responding thermometer and color-coded functionality allows a user to quickly scan electrical and plant components and focus on identifying anomalies without constantly evaluating specific temperature values on the display.

Other useful features include a bright backlight for easy viewing of the multifunction display, trigger lock for continuous measurements without trigger fatigue and a tripod mount for more extended, fixed location measurements (using the TR100 tripod available separately). Useful data features like data hold, minimum, maximum, average and differential values (T2-T1) yield added insights to identify trends or unusual conditions while conducting equipment inspections.
