The Extech 401025 Foot Candle/Lux Light Meter gives clear light readings in Lux and foot-candles. It reads low to very bright light with confidence, and it stays steady in varied work settings. You get quick setup and simple operation, so checks feel smooth and repeatable.
Sensor accuracy and control
A precision photodiode and a colour-correction filter help the sensor stay true under different sources. Cosine correction improves results when light hits at an angle, and the meter keeps output stable across real scenes. The fast mode captures rapid change, while the slow mode calms a fluctuating display for easy note-taking.
Ranges and output you can record
Three Lux ranges and three foot-candle ranges let you match the job and avoid overload. A built-in analogue output sends 1 mV per count to a recorder, so you can log or plot readings with little fuss. The included 9 V battery means you can begin checks right away and keep workflows moving.
You can shift from quick spot checks to longer surveys without changing tools. The meter stays practical for site work, bench work, and basic audits, and the control response stays fast and predictable. It fits roles where you need clear readings and simple capture, and it avoids extra steps that slow teams down.
