Changzhou ChuangJie Lightning Protection Co. Ltd. (CJP) is a manufacturer and exporter of varistors(MOV) ,surge protective devices(SPD) & special testers for MOV & SPD. Varistor is a component, whose conductance ,at a given temperature ,increase with voltage. Varistor is also named voltage dependent resistor(VDR), or voltage sensitive resistor(VSR). Varistor is made of zinc oxide together with a small amount of other metal oxide additives, therefore it has a name of metal oxide varistor(MOV). CJ/T2-65kA Surge Current Tester is mainly applied to Class II test and inspection for SPD(Surge Protective Device) and non-linear components(MOV,GDT,ABD,TSS,and the(like) in accordance with IEC61643-1 & GB18802.1-2002. It can deliver 8/20 surge(impulse) current with the peak value 65kA, which can even be superposed onto SPD’s maximum AC r.m.s continuous operating voltage(UC).

Varistor is made of zinc oxide together with a small amount of other metal oxide additives, therefore it has a name of metal oxide varistor(MOV). CJ/T1007 Varistor Tester is mainly applied to inspect voltage limiting non-linearity components,e.g. varistors, arrester’s valve plates, ZENER diodes. CJ/T1007 can measure two basic parameters of the DUT: 1)Varistor Voltage UN: also known as conductive voltage, is the voltage drop across the DUT when 1mA DC current is applied to it. 2)Leakage Current IL: is the current which passes through the DUT when it is energized at the voltage of 75% UN or 83% UN.

Abbe Refractometer This instrument is designed for the measurement of refractive index(nD) and the average optical dispersion(NF-NC) of the transparent, the semitransparent and the solid matter (mostly transparent). It was connect with a circulating thermostatic bath, can measure the refractive index in 0?~50?. It also measures the Brix percentage of sugar solution[(0-95)? which is equal to th refractive index1.333-1.531]. It was widely used in oil industry, fat industry, pharmaceutical factories, paint, food processing, chemistry, sugar refineries, geologic etc., and relative factories, school and research center.

Digital Refractometer Digital Refractometer is a kind of digit product based on the hand-held refractometer. The gigit can be displayed. Comparing with the hand-held refractometer, it is more intuitionistic and accutate. It is equipped with ATC. • Digital for Brix • Digital for Salinity • Digital for Clinical Protein • Digital for Battery/Antifreeze/Cleaning Fluid • Digital for °Oe Tester • Digital for Honey Tester

Hand Held Refractometer The Hand Held Refractometers are specially designed for measuring the concentration of many kinds of solution listed as following: Juices?Beverages?Honey? Salt water?Brine?Cleaning fluid?battery fluid?Antifreeze and Industrial fluids etc. And they can also test for the proportion of the water-soluble solution. They can be easily used and they are competitive in price. You only need to drop some water on the prism and then make it towards to the sunlight. Then the reading of the concentration will appear. And ATC means automatic temperature compensation. • Brix • Salinity • Clinical Protein • Battery/Antifreeze/Cleaning Fluid • Alcohol • Honey Tester • Contact Lens Tester • Grape Tester • Soybean Milk Tester • Gem Tester • °OE Tester
