Main industrial uses:
- Measure the brightness of LCD, PDP, CRT, OLED, LED, cold cathode tube, etc.
- Measure the transmittance of LCD polarizers, various optical films and filters
- Luminance measurement of road lighting, tunnel lighting, etc.
- Airport lighting facilities, determination of maritime route markings
- Medical lighting, electronic medical record monitoring and management, medical photos
- Determination of illumination marks on car license plates
- Measurement of brightness of various lighting facilities
- Luminance measurement of induction zone in visually impaired patients
- Determination of ground reflection brightness
Three different angle measurement probes are optional and can be installed on the BM-9AC body for joint use.
BM-9A
The successor model of the portable luminance meter BM-9
Detachable probe, simple and lightweight
product description
This product is a simple and lightweight handheld luminance meter. The probe can choose from 3 different measurement angles and has a wide range of uses. In addition, the probe can be separated from the main body, so it is also suitable for installation in automatic measurement systems and suitable for use in production lines.
Features
- Portable, low price, multifunctional.
- Three different probes can be selected and replaced, and the measurement results can be automatically recognized and displayed directly.
- USB built-in design realizes PC communication function, so it can be used in production lines and installed in automatic measurement systems.
- Using the keyboard, you can select correction coefficients, deviation measurement and other functions.
