Extech 42510A Wide Range Mini IR Thermometer
The Extech 42510A is a compact handheld infrared thermometer designed for non‑contact surface temperature measurement across a wide swath of industries. With a range from about ‑50 °C to 650 °C (‑58 °F to 1200 °F) and a 12:1 distance‑to‑spot ratio, it offers quick, field‑ready readings and useful features such as laser aiming, backlit display, data hold and alarms for pro‑level convenience.
Description
The 42510A combines portability and capability in a slim, ergonomic housing (~82 × 42 × 160 mm, ~180 g). Point the device at a surface, pull the trigger, and the built‑in laser pointer helps aim the correct spot. The optics give you a 12:1 distance‑to‑spot ratio, meaning at a given distance the area measured remains reasonably small for accurate readings. The measurement range spans roughly ‑50 °C up to +650 °C, making it versatile for HVAC diagnostics, building inspections, electrical/industrial maintenance and more. Emissivity is adjustable (0.10 to 1.00) so you can tailor the measurement for different surface materials (painted, metal, oxide, etc.), thereby improving accuracy. The unit features a backlit LCD for use in dim areas, supports min/max and data‑hold functions, and includes programmable high/low alarms so you are alerted when readings exceed set thresholds. Auto power‑off conserves battery life (9 V battery included) and it ships ready with a pouch case. Overall, the 42510A balances wide‑range performance with everyday usability in a compact instrument.
Features
-
Wide non‑contact temperature range: about ‑50 °C to +650 °C (‑58 °F to 1200 °F).
-
Distance‑to‑spot (D:S) ratio of 12:1, allowing measurement from a moderate distance while still targeting a reasonably sized area.
-
Built‑in laser pointer for accurate targeting of the measurement spot.
-
Adjustable emissivity from 0.10 to 1.00, enabling more accurate readings on varied surface types.
-
High/Low alarm set‑points with audible alerts, letting you configure thresholds for quick monitoring.
-
Backlit LCD display for visibility in low‑light conditions and data‑hold / MIN/MAX memory for capturing extremes.
-
Auto power‑off feature (with optional lock mode) to conserve battery when idle.
-
Compact, lightweight design (~180 g) with pistol‑grip form factor and included 9 V battery.
-
Accuracy specification: for much of the range the basic accuracy is ±(1% of reading + 2 °F / 1 °C) in IR mode.
Includes
- 9 V battery
- Pouch case
