The Martindale LM195 Lux Meter can measure and verify the performance of existing lighting systems. It can also be used to commission new lighting installations.
It is particularly useful when checking that lighting systems in offices, industrial settings and commercial institutions are compliant with the levels required for a healthy working environment. To this end, the Martindale LM195 Lux Meter can measure light up to 200 000 lux and has a resolution of 0.1 lux within the 200 lux range.
Moreover, this light meter includes integrated correction factors for LED, incandescent and fluorescent lighting ensuring that it can be used to verify all types of lighting installations including both conventional and LED systems. This extends the Martindale LM195 Lux Meter’s scope-for-use beyond that of its sister product's, the Martindale LM192 Lux Meter.
As well as measurement versatility, the Martindale LM195 Lux Meter is also optimised for environmental versatility and as such includes a durable design with a detachable light sensor; these features make it suitable for use within a variety of challenging, rugged environments and provide access hard-to-reach areas.
In addition to versatility, this tester is also designed to facilitate easy operation and as such features an operating system that has been laid out intuitively for simple navigation.
The Martindale LM195 Lux Meter is a versatile, easy-to-use, general light meter with a wide scope-for-use.
