PROFESSIONAL LUXMETER LIGHT INTENSITY METER The GM 1020 luxmeter by Benetech is a tool for measuring light intensity with a range of 1-200,000 Lux . The device finds applications in many areas. The meter can be used in the electro-optical industry. It is also used for inspection purposes in rooms where people work or reside, as well as in plant and animal breeding. Key features of the device: A wide range of additional measurement functions: The device can measure not only current, maximum, and minimum light and temperature values, but also the illuminance difference, time-integrated illuminance value, and average illuminance value. Automatic data storage function for illuminance (up to 1900 groups) or manual data recording (up to 60 groups). Wide measurement range (0 to 200,000 lux) and automatic range shift function. Included with software for analysis of collected data on a computer, which allows users to easily operate the meter. Fast response time , high mobility and one-handed operation. Rotatable head - the sensor can be rotated 180 degrees. Backlit display. The device is factory calibrated and ready to work.
