Model: LM-120 照度计

Light Meter with Auto Ranging

 

The Amprobe LM-120 light meter measures the visible light from fluorescent, metal halide, high-pressure sodium or incandescent sources. It is a portable, easy-to-use digital light meter designed for simple one-hand operation reading in Lumen (lux) or footcandle (fc) units. The LM-120 measures a wide range of light up to 20,000 fc or 200,000 lux with an accurate, high resolution of 0.01 fc/lux. This unit is Autoranging plus manual ranging with ability to Zero out the reading before taking a measurement.

 

Use the LM-120 light meter to measure the illumination level in the interior and to switch off or reduce or increase the output level of lighting fixtures. Reduce the energy burden of the building by significantly increasing the efficiency of its lighting system.

 

One lux is the illumination from a one candela lamp perpendicular to a surface one meter squared at a distance of one meter. One fc is the illumination from a one candela lamp perpendicular to a surface one foot squared at a distance of one foot. 1 foot-candle = 10.764 Lux and 1 lux = 0.09290 footcandles.

 

 

 

 

Measure in Lux or Footcandles, front panel switchable

Measuring Range to 200,000 Lux or 20,000 Foot candles

Silicon photodiode sensor and filter

Data Hold to freeze reading on the digital display

MIN / MAX ability to show high and low readings

Autoranging plus Manual Range

Zero function to null display before a reading

Auto Power Off to save battery life

Includes protective sensor cap

Large, 3-1/2 digit display
