Spectrometer Spectral Radiation Illuminance Meter with 8G Data Storage Card

Spectrometer Spectral Radiation Illuminance Meter with 8G Data Storage Card
Advantages
▲Long-focus optical system, 2nm optical resolution, wider wavelength range, can measure LED broad spectrum light source, can also measure energy-saving lamps CFL, high and low pressure sodium lamps HID and other narrow-spectrum light sources.
▲With automatic zero calibration and zero compensation technology, the maximum integration time can be longer, can measure the weaker light signal;
▲With electronic shutter technology, the minimum integration time can be as small as 50us, which can measure stronger light signals;
▲Quick switch on/off, one key test, more convenient to use.
▲Large size HD IPS capacitive touch screen, high display resolution, one screen display more content, bright colors, can be used outdoors;
▲Large battery capacity, 24 hours long test use time.
