Key Features

  • Dual-scale meter measures visible light from fluorescent, metal halide, high-pressure sodium, and incandescent sources up to 200,000 lumens per square meter (lux) or 20,000 footcandles (fc), with auto-ranging and zeroing functionality
  • Silicon diode sensor and filter are designed for indoor use at altitudes below 2,000 meters
  • User-selectable auto or manual ranging, data hold freezes readings on the display, minimum and maximum recordings display the lowest and highest reading, zeroing capability resets the null point, and angled light cosine correction corrects for angled light
  • Complies with Japanese Industrial Standard (JIS) C1609:1993 and CNS 5119 general A-class specifications, and European Community Directives: 89/336/EEC (Electromagnetic Compatibility) and 73/23/EEC (Low Voltage) as amended by 93/68/EEC (CE Marking)
  • Powered by a 9V battery (included), and includes a 1.5-meter wire for positioning light sensor, and a protective sensor cap

Product Description

The Amprobe LM-120 light meter measures up to 200,000 lumens per square meter (lux) or 20,000 footcandles (fc) of light output from fluorescent, metal halide, high-pressure sodium, and incandescent sources, has a silicon diode sensor and filter, and is designed for indoor operation at altitudes below 2,000 meters. The meter has manual ranging, a data hold feature to freeze readings on the display, minimum and maximum recordings to display the lowest and highest reading, zeroing capability to reset the null point, and angled light cosine correction to calculate the amount of light, regardless of the light's angle.

The meter is powered by a 9V battery (included) which has an average life of 200 hours. The sensor has a 1.5-meter wire for positioning the light sensor, and a protective sensor cap.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Light meters measure luminous intensity, or light, and are commonly used in a wide range of industries and settings including photography, video filming, galleries, schools, laboratories, and greenhouses to help determine the brightness of light.

Amprobe manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA.
