Features [Highly Sensitive Sensor] Equipped with a highly sensitive sensor, this detector has fast response, low power consumption, simple detection circuit, excellent stability and long service life. [Multiple Alarm Modes] The gas detector offers multiple alarm modes including sound, light and vibration, ensuring immediate and noticeable alerts in case of gas leaks. [Adjustable Sensitivity] The alarm sensitivity can be adjusted, providing real-time information about gas leakage. When the gas concentration exceeds either of the two alarm levels (high and low), an alarm will be triggered immediately. [Flexible Probe] With a 26cm long probe, this halogen gas detector allows it to be easily bent along pipes or into tight spaces to detect gas leaks in any direction. [Multi-purpose] This refrigerant gas detector is suitable for detecting all halogen gases, including chlorine and fluorine, it can also detect gases such as ethylene oxide and ethanol used in medical equipment, halon gas in fire fighting systems, air conditioning and refrigeration systems. 1.
