Features [Highly Sensitive Sensor] Equipped with a highly sensitive sensor, this detector has quick response, low power consumption, simple detection circuit, excellent stability, and long lifespan. [Multiple Alarm Modes] The gas detector offers multiple alarm modes including sound, light, and vibration, ensuring immediate and noticeable alerts for gas leaks. [Adjustable Sensitivity] The alarm sensitivity can be adjusted, providing real time feedback on 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 easy bending along pipelines or in confined spaces to detect gas leaks in any direction. [Multi Purpose] This refrigerant gas detector is suitable for detecting all halogen gas, including chlorine and fluorine, can also detect gas such as ethylene oxide and ethanol used in medical equipment, halon gas in firefighting systems, air conditionin Specification: Item Type: Halogen Gas Detector Material: ABS Detected Gas: CFCs: R11, R12, R500, R503, etc. HCFCs: R134a, R404a, R125, etc. HCFCs: R22, R123, R124, R502, etc. Range: 0-1000PPM Resolution: 1PPM Maximum Sensitivity: R12 R22 and T134A at 0.5Oz per Year (14g per year) Preheating Time (T90): 30 seconds Response Time (T90): <10 seconds Sampling Method: Diffusion type Battery: 3 x 800mAh AAA alkaline dry battery (shipped with matching battery) Running Time: >6 hours Display: LCD display, with automatic backlit lighting Direct Reading: Sensor concentration reading, battery level, concentration unit, temperature Alarm Settings: Low sensitivity alarm function, high sensitivity alarm function settings Alarm: Sound, light emitting diode, vibration indication alarm, voltage undervoltage indication Audio Prompt: The higher the beep frequency, the higher the concentration Package List:1 x Halogen Gas Detector3 x Battery1 x Storage Bag Package List 1 x Halogen Gas Detector 3 x Battery 1 x Storage Bag
