Sensitivity: 6Gr/year Working temperature: 0--52 Response Time: Instantaneous Detection method: continuous, unlimited Reset time: 2-10 seconds Power supply: Aa battery (6Vdc) not included Dimensions: 229*65*65 (mm) Probe length: 20Cm High quality: The leak detector adopts high-quality sensor, which has high working sensitivity and long service life. Adjustable sensitivity: This halogen leak detector has the function of stepless speed regulation of sensitivity, and the sensitivity can be adjusted during detection; by adjusting the sensitivity, all instruments can be automatically adjusted to the best detection state. More stable work: built-in voltage regulator, high precision, ultra-low power consumption IC design, more stable work Power-on reset and automatic tracking: The leak detector has a power-on reset and automatic tracking function, which can ignore the halogen gas concentration level of the environment. Applicable: The leak detector can be used not only for automotive air-conditioning systems, but also for the detection of all halogen-containing refrigerants
