This handheld meter checks workplace and site lighting with speed and clarity. It gives reliable lux or footcandle values for audits, safety checks, and routine surveys. The readings are steady and easy to read, so you can move quickly between areas while keeping notes clear.

Simple, accurate light surveys

A silicon photodiode and a dedicated filter give a response tuned to LED day white light. The instrument follows the JIS C 1609-1993 standard and supports a user set light source for non LED checks. Results stay consistent across a wide range, which helps you compare spaces with confidence.

Built for real world use

A backlit LCD with a bargraph shows trends at a glance. You can use data hold and min, max, and average to compare areas while the meter samples quickly. ATP LX-3809 LED Light Meter keeps task flow simple with auto or manual ranges and clear over range prompts.

A fixed sensor on a coiled metre long lead reaches into awkward spots and stays safe under a lens cap. An impact resistant ABS case and auto power down help the tool last and save batteries. Calibration points are listed so routine certification remains easy to file and track.

ATP LX-3809 LED Light Meter

ATP LX-3809 LED Light Meter helps you check workplace and site lighting with clear, steady readings. Use it to record lux or footcandles during audits, safety checks, and routine surveys, then move on with confidence.

Readings stay easy to follow thanks to a backlit screen and a quick bargraph view. You can keep notes tidy with data hold, while the meter continues to sample at a steady pace.

Consistent readings for modern lighting

A silicon photodiode sensor and LED filter give a response tuned to LED day white light. ATP LX-3809 follows JIS C 1609-1993 and also lets you set a light source option when you need checks beyond LED.

Cosine correction helps the sensor respond well when light hits from different angles. This supports more reliable comparisons between rooms, walkways, and work areas.

Designed for quick checks on site

A fixed sensor on a coiled lead reaches into awkward spots while keeping the meter body in hand. ATP LX-3809 LED Light Meter also provides clear range prompts so you can avoid confusion during fast rounds.
