Description

Kewtech KEW337 Light Meter

The Kewtech KEW337 Light Meter is capable of measuring light intensity from 0 to 39,990Lux with a resolution from 0.01Lux to 10Lux and accuracy of ±3% ± 5 digits. It can display readings in either Lux or foot candles and has an autoranging function that ensures maximum precision wherever possible. Manual ranging is also available.

Readings are taken via the fixed Si photodiode light detector positioned at the top of the Kewtech KEW337. Responses are given in less than half a second and readings will be clearly displayed on the light meter’s digital screen. A data hold function keeps the reading on screen and the reading is updates twice per second.

The Kewtech KEW337 comes supplied with a battery, an instruction manual and a carry case. It automatically goes to zero on power up and has a battery life of 170 hours.
