Digital Lux Meter LX821 ,UV light meter
Specifications
Precise and easy readout
High accuracy
Use of LSI-circuit to give high reliability and durability
Product Introduction
This Digital Illuminance Meter is a precise instrument used to measure illuminance in the field. Illuminance is the total luminous flux incident on a surface per unit area. This meter can be used to measure illuminance in Lux level with wide measuring range 0 to 200,000 Lux. It is compact, light-weight and easy to operate owing to its construction and design.
This electronics tool is mainly used to detect the brightness (Lux level) for brightness and lighting design, adjustment and maintenance. It is an ideal tool for brightness measurement in a very wide range of places including offices, factories, warehouses, schools, libraries, galleries, hotels, hospitals, operation wards, auditoriums, indoor gymnasiums, etc. The obtained data will become very useful information to establish and maintain adequate and comfortable environments for human activities. Brightness is one of the most concerned parameter for indoor environments and obviously different purposes will require different brightness levels.
