WINTACT WT81B BLUETOOTH LUXMETER PRECISION LIGHT METER LIGHT INTENSITY METER The digital luxmeter is a professional illuminance and brightness measuring instrument, which can be used in light intensity measurement engineering, quality control, prevention and light intensity measurement in all environments such as factories, schools, offices, street lighting, etc. The luxmeter has the following functions: Measuring the current illuminance and temperature. Measuring the difference value, maximum value and minimum value. Selection between illuminance and temperature measurement. Measurement range is (0~200000) lux with automatic measurement equipment switch. Automatic and manual storage of illuminance measurement data. Auto power-off setting. Backlit LCD display and data storage. The digital lux meter is equipped with an app that facilitates all kinds of operations via Bluetooth. It allows you to save and analyze results in a mobile app compatible with Android 5.0 and higher. LUXMETER WITH BLUETOOTH CONNECTION Mobile App Thanks to the mobile app, you can analyze measurements and save data in real time. The app displays actual light intensity measurement data on a graph. It also allows you to review the data later and delete unnecessary measurements. Data can be saved and stored in the phone's memory, exported to datasheets and transferred to a computer. The app is compatible with devices running Android 5.0 and higher.
