SF6 Trace Gas Leak Detector Q200

Ultra High Sensitivity SF6 Gas Leak Detector - Q200 Q200,a nearly 30-years of high quality product, is the ultimate in instrumentation for high-sensitivity tracer gas leak detection. It is designed to locate and quantify leaks in industrial, military and laboratory applications. The first generation Q200- Modle:iTi Qualitek 200 - SF6 leak detector was developed by AI Qualitek in UK in 1991. The world's advanced Electron Capture (ECD) principle is used in the SF6 Leak Detector Q200. The advent of ECD principle makes the qualitative detection of electron-negative substances achieve a qualitative leap, which is one of the three breakthroughs in trace detection in the 21st century. In 2002, Uson Ltd., who is the World Leader in Leak Testing in USA took over the production and sales of Q200,Modle:Qualichek 200. In 2015, all of the manufacture and business was transferred to D-Industrial Shanghai. After nearly 30 years of iterative update, the Q200 now has higher accuracy, sensitivity and stability, and is close to perfect in detection performance. At present, Q200 is widely used in electric power, High-Voltage Switchgear,laboratory fume hood, building ventilation, mine ventilation, torpedo head and military products, helicopter rotor blades, fire extinguisher testing, storage vessels, gas delivery system and other industries related to SF6 gas. Q200's high precision, sensitivity and stability and other outstanding performance have been affirmed by the users. Advantages:  1. Portable and easy to use 2. Responds to SF6, refrigerants and other electron capturing compounds 3. Fast response and recovery 4. Locates position of leaks 5. Quantifies the leak rate 6.  Displays leak rate or concentration 7. Measurement storage facility Details: The Qualichek 200 is a portable instrument, supplied in a carrying case holding the power supply and electronics,a small cylinder of compressed argon gas, and the main display panel. The detector is mounted in a hand-held probe, attached to the main unit by a 10 ft (3.5 meter)umbilical connection. A display panel is mounted in the hand probe enabling the operator to monitor measurements even when working in difficult locations.   The instrument is extremely easy to use, and provides highly accurate leak rate measurements. The response is instantaneous with quick recovery from exposure to high concentrations of trace gas.   Q200 Facilities: 1.Adjustable audible alarm, activated when user's set leak rate limit is exceeded 2.Factory calibrated for SF6 3. Simple user recalibration facility 4.Diagnostic menu identifies fault conditions Specifications Model Qualichek 200 Description Ultra high sensitivity trace gas leak detector for accurately locating and quantifying leaks Leak Rate 1 x 10-8  ml/s SF6(With optional capillary inlet,1 x 10-10  ml/s SF6) Concentration Sensitivity 0.01 ppm Dimensions(h x w x d) Case: 43 x 40 x 23 cm(17 x 16 x 9 in) Weight Hand held probe: 0.9 Kg (2.0 lbs) Output RS232 interface port Analogue 0-2 V Sensor Electron capture (red) Life time of sensor       above 10 years Display Alpha numeric VFD Response 1 sec (85% of reading) Detects SF6 and other electron capturing compounds Options Calibrated leaks Argon gas filling valve assembly Operating Time From Battery 10 hours Applications Helicopter roter blades; High-voltage switchgear; Approved for ASHRAE 110; Gas delivery systems; Torpedo heads; Testing fire extinguishers; Building ventilation rate studies; Checking hazardous materials; Storage vessels.
