Versatile: Multi-function illuminance meter can meet any of your needs, with data retention, relative value measurement, peak value measurement, automatic/manual range switching, maximum/minimum, zero calibration, automatic shutdown, LCD high-definition screen, unit conversion FC/Lux, battery low voltage indication function. Testing is easier: sampling time is less than 0.5 times per second and results are immediate. Data saving makes debugging more convenient, without worrying about data loss for a long time, the maximum display value is 2000 counts. Also, extracting tested data makes your work smoother. High Accuracy: A light meter is an instrument dedicated to measuring luminosity and brightness. The product is equipped with silicon components, which can accurately measure light and brightness, reduce errors, and make the illuminometer measurement stable and reliable. The measurement range is 0-200000Lux/0-20000FC, and the measurement resolution is 0.01Lux/0.01FC. LED display: This light meter has a large LED backlight screen, allowing users to easily cope with harsh environments such as darkness, easy to read, and free users from the constraints of time and place. Measurement type range: suitable for measuring LED incandescent light, white LED light, red LED light, yellow LED light, green LED light, blue LED light, purple LED light.
