The TDL1000 laser ammonia sensor is a new type of gas sensor developed by our company. It utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) and multi-pass cell technology, integrated with a high-performance processor and low-noise signal conditioning circuitry. Key advantages include a long service life, excellent stability, high precision, rapid response, no need for calibration, and low maintenance costs. It is suitable for a wide range of gas detection applications in environments where ammonia may be present, such as the petroleum, chemical, and metallurgical industries, as well as cold storage facilities, dairy plants, fertilizer factories, and livestock farms.
