Open circuit laser gas detector is an instrument that utilizes the near-infrared spectral absorption characteristics of gases. The open tunable semiconductor laser absorption spectroscopy (TDLAS) technology is based on the principle of detecting gas concentration in an open spatial area through the degree of absorption of specific wavelength light by gas, with a detection distance of up to 120 meters.
Open circuit laser gas detector is a new type of gas detection instrument developed by our company, which is an outdoor use product. Made with high-performance large-area photosensitive detectors and microcontroller technology, combined with sophisticated SMD technology, it has good repeatability and temperature and humidity characteristics, as well as long service life and easy operation. Its output signal is a standard signal of 4-20mA. This product is designed in accordance with national standards and has advantages such as beautiful system appearance and rich functions compared to traditional products.
Fast response speed, high sensitivity, good repeatability, capable of real-time detection and online measurement
