A split illuminance meter is a professional instrument for measuring luminosity and brightness. It is used for light intensity measurement engineering, quality control, health prevention, and light intensity measurement in various environments, such as factories, schools, offices, traffic routes, homes, etc. Features: Split Type Design: the separation of the measurement part and reading part with retractable spring can avoid the influence of strong light on the naked eye. Wide Measurement Range: 0-200000 lux and 0Fc 20000Fc with switchable units of Lux / Fc and temperature units of / . Large illumination probe effectively increases the measurement area with better processing efficiency in higher or narrower measurement environment. Easy to Connect with APP by BT: You can get the illuminometer states and testing data by using the mobile phone App which is more convenient and smarter. Easier to store the test data by mobile phone. Max / Min / Difference Value / Data Hold functions, high accuracy with automatic range and quick response. Upgraded dual color mode color screen with backlight for easy reading. Widely used for monitoring light intensity in homes, laboratories, office, schools, indoor farming, etc. Specifications: Material: ABS illuminance Probe: Silicon photodiodes illuminance Range: 0-200000Lx (0~18581Fc) 1 Gear: 0~999.9Lx (0~92.894Fc), 0.1Lx (0.01Fc), 3% 2 Gear: 1000~9999Lx (93~929Fc), 1Lx (0.1Fc), 4% 3 Gear: 10000~99999Lx (929~9290Fc), 10Lx (0.9Fc), 4% 4 Gear: 100000~200000Lx (18581Fc), 100Lx (9.3Fc), 4% Temperature Range: -10~65 (14~149), 0.1 (32), 1.5 (35) Item Size: 150 * 63 * 30mm / 5.91 * 2.48 * 1.18in Item Weight: 230g / 8.11oz Package Weight: 737g / 25.99oz Package Size: 27 * 21 * 6.5cm / 10.63 * 8.27 * 2.56in Package List: 1 * Digital Lux Meter 1 * Storage Case 1 * USB Line 1 * User Manual (English)
