The KDZD400 is a portable, pump-suction gas analyzer designed for precise detection of trichloroethylene (C₂HCl₃) and other volatile organic compounds (VOCs). Using high-performance imported sensors (electrochemical, PID, or infrared), it delivers real-time concentration readings with a resolution down to 0.001ppm. The 2.31-inch color LCD provides intuitive operation, while a built-in rechargeable battery supports long-term field use. With a wide operating temperature range (-40°C~+70°C), data storage for 100,000 records, and multiple alarm options, it is a reliable solution for industrial safety and environmental monitoring.
