Extech 42512 Dual Laser InfraRed Thermometer
The Extech 42512 is a professional non‑contact infrared thermometer equipped with dual laser pointers for precise targeting, a rapid 0.15‑second response time, and a measurement range from approximately ‑50 °C to +1000 °C (‑58 °F to 1832 °F). It’s designed for accurate surface temperature checks in industrial, HVAC, or maintenance environments.
Description
This thermometer is built to deliver fast, accurate surface temperature measurements from a safe distance. The dual laser system ensures the user sees exactly where the measurement spot is: when the two laser beams converge, you are at the correct distance for the target spot (approximately a 1 inch/2.5 cm diameter at 30 inches/76 cm away). The optics are 30:1 (distance:spot) allowing you to measure a relatively small spot from a further distance — reducing risk when working with hot or hard‑to‑reach surfaces. With a full temperature range up to around 1000 °C (1832 °F), it covers many demanding application areas. Emissivity is adjustable from about 0.10 to 1.00, so you can calibrate for different surface types (painted, metal, textured) to improve accuracy. The dual‑LCD backlit display allows you to view current reading and maximum reading, even in low‑light conditions. It also offers features such as high/low alarm set‑points with audible alert, “lock” mode for continuous readings, auto‑power‑off for battery conservation and durable double‑moulded housing for rugged use. The unit typically ships with a 9 V battery and a pouch case, making it ready for field use. All in all, it is a versatile tool for professionals needing reliable temperature sensing at a distance.
Features
-
Temperature measurement range from about ‑58 °F to +1832 °F (‑50 °C to +1000 °C).
-
Distance‑to‑spot (D:S) ratio of 30:1, meaning you can measure a 1″ (≈2.5 cm) spot from about 30″ (≈76 cm) away.
-
Dual laser aiming system: two laser pointers that converge to indicate the correct measuring spot location (1″ diameter at convergence).
-
Fast response time ~0.15 seconds, enabling quick detection of temperature changes or hot spots.
-
Adjustable emissivity from about 0.10 to 1.00 to accommodate different surface materials for better accuracy.
-
Back‑lit dual LCD display for viewing both current and maximum values, even in dim lighting.
-
Programmable high/low alarm set‑points with audible alert to flag out‑of‑range temperatures.
Includes
- Pouch case
- 9 V battery
