HLD-200 is a newly high performance intelligent halogen leak detector.The new shell designed with LED displaying is elegant,easily-carried,easy operation,visual and clear display,etc. features: visual displayand single light diode displays the leak degree in large range in the form of "gradullay lights the light" providing 6 levels of sensitivity to set the real-time cycle ajustment easy operation with pushbutton battery checked function with tricolor display detect all kinds of halogenated refrigerants. the high effective true mechanical pumping provides positive airflow through sensing tip,which can improve the sensitivity and response speed. applicable areas: 1.the leak-detect in vocation of freeze,refrigeration,and air-conditioner 2.the leak-detect for air-conditioner in the car 3.it will respond to all halogen gases(including Chlorine and Fluorine). including CFCS e.g.R12,R11,R500,R503 etc. HCFCS e.g.R22,R123,R124,R502 etc. HFCS e.g.R134a,R404a,R125 etc. And other mixtures,e.g.AZ-50,HP62,MP-39,etc. 4. detect Ethylene Oxide gas leaks in hospital sterilizing equipment(it will detect the homogenate carrier gas.) 5. detect SF-6 in high voltage circuit breaks 6. detect most gases including Chlorine,Fluorine and Bromine(halogen gas) 7. detect cleaning agents used in dry cleaning applications such as perchloroethyl. 8. detect halogen gases in fire-extinguishing system. Specification and parameters: power supply:3VDC(2XAA battery) Max.Sensitivity:R12,R22,R134a are certified to 3g/gr probe life: about 30h working temperature:0~52C battery life: 30h under normal condition working model:continuous,no limit response time: instant warm-up time: about 6s resetting time: 2s weight: 200g size: 17.0x3.4x5.5cm probe length: 30.5cm contact me: sales07(at)kibnt dot com
