The LT5100 is a laser transmissometer that measures transmittance and visibility with high precision and directly outputs transmittance and visibility values. It has the function of modulation and transmission and synchronization mechanism to eliminate the influence of stray light. Low temperature drifts constant current source, 24-bit high precision AD conversion for accurate measurement. With high-bright OLED display, RS485 digital communication. It also comes with a straightening and fine-tuning platform that supports online calibration.
