FAQ
Q1: What is the core sensor technology of this detector, and what is its lifespan?
A: We primarily use high-performance electrochemical sensors, which offer advantages such as high sensitivity, fast response, excellent selectivity for carbon monoxide, and low power consumption. Under normal industrial conditions, its average expected lifespan is 2-3 years, depending on gas exposure concentration and environmental conditions (e.g., temperature, humidity).
Q2: What is the detection range of the instrument, and how accurate is it?
A: The standard range is 0-1000 ppm (higher ranges can be customized, such as 0-2000 ppm or 0-5000 ppm, suitable for high-risk scenarios like steel and chemical industries). The resolution can reach 1 ppm, and the accuracy is typically within ±3% FS (full scale). All instruments undergo strict calibration and testing before leaving the factory.
Q3: Does it have explosion-proof certification, and what hazardous areas is it suitable for?
A: Yes. Our fixed gas detectors hold explosion-proof certification issued by the National Center for Quality Supervision and Inspection of Explosion-proof Electrical Products, meeting explosion-proof standards such as Ex d IIC T6 Gb / Ex tD A21 IP66 T80°C. They are suitable for Zone 1 and Zone 2 hazardous gas environments, as well as Zone 21 and Zone 22 hazardous dust environments. Please confirm the model based on your specific area classification.
Q4: What is the protection rating, and can it be used in harsh environments (high temperature, high humidity, dusty)?
A: The enclosure protection rating is typically IP65, ensuring complete dust resistance. The probe and transmitter are designed to operate within a temperature range of -20°C to +50°C and a humidity range of 0-95% RH (non-condensing). For extreme temperatures, corrosive gases, or heavy dust environments, we offer optional accessories such as specialized sampling probes, cooling and dust removal filters, or corrosion-resistant enclosures.
