Professional Low Light Illuminance Portable Refractometer Lx1334e

This product is a high-precision professional-grade digital illuminance meter, and its sensor adopts silicon photocell detector and built-in visual correction filter. The spectral characteristics have been strictly corrected, and the measurement is accurate and stable. its V(N) matching error is small, and its resolution is high. It is suitable for accurately measuring the visible light emitted by various fluorescent lamps, metal halide lamps, high-pressure sodium lamps or incandescent lamps, LED lamps and other light sources.
The instrument adopts split design as a whole, which is convenient to carry. The probe has a handle,which is convenient for users to measure. The plug-in head is designed to prevent reverse connection, so it is easy to plug in and out, and it will not be inserted backwards. The shell of the main engine is covered with glue,which is shock-proof and fall-resistant. Built-in button battery, slim body and strong endurance.
* The resolution is up to 0.01Lux, which can detect low light and weak light.
* The matching error of V (λ) is small, which can accurately measure visible light with different color temperatures.
* High-definition LCD display with backlight function.
* It has the functions of numerical holding and peak holding.
* Low voltage prompt function.
* Automatic shutdown function.
* Three button-type batteries, the endurance is 1.5 times that of ordinary batteries.
