Description

Martindale LM192 Light Meter

The Martindale LM192 Light Meter is a useful lux meter that is capable of measuring illumination from 0 to 200,000Lux with a maximum resolution of 0.1Lux and accuracy of ±3% (with incandescent lamps). These capabilities make the instrument ideal for measuring light levels in offices, workshops and other working environments in order to ensure that spaces are safely and comfortably lit.

The Martindale LM192 has a detachable light sensor that allows the user to measure light levels in precise locations such as in front of a computer screen or on a factory floor. Min/max readings are available on the meter and the user can control the light level as well as picking the unit, range, and using data hold to freeze a reading on screen.
