Alat ukur cahaya ( lux meter) adalah alat yang digunakan untuk mengukur besarnya intensitas cahaya di suatu tempat. Besarnya intensitas cahaya ini perlu untuk diketahui karena pada dasarnya manusia juga memerlukan penerangan yang cukup. Untuk mengetahui besarnya intensitas cahaya ini maka diperlukan sebuah sensor yang cukup peka dan linier terhadap cahaya. Sehingga cahaya yang diterima oleh sensor dapat diukur dan ditampilkan pada sebuah tampilan digital.

Untuk Digital Lux Meter PCE EM-882 merupakan produk yang lengkap karena terdapat 4 pengukuran sekaligus, yaitu untuk pengukuran cahaya, suara, kelembaban dan temperatur.

* Humidity meter
* Temperature
- The 4 in 1 multi-function lux meter includes sound sensor,
light sensor, temperature sensor and relative humidity.
- The 4 in 1 multi-function lux meter combines a noise analyser, a light meter, a thermometer and a relative humidity.
- The lux meter is especially suited to educational settings with the aim of measuring all 4 parameters and can also be used in both a professional setting or at home.
- The lux meter with all its sensors, comes in a light carrying case and is both easy and quick to use.
- Test environmental conditions directly.
* 17mm LCD display with 4 digits
* Hold function
* Auto OFF to conserve battery power
* Battery power inidcator
* ABS enclosure
