Product Description Hengfeng ground resistance tester is a high-precision test instrument used in various fields such as substations for testing grounding resistance and related parameters. The instrument has the characteristics of lightweight, small dimensions, convenient carrying, strong anti-interference performance and high accuracy. It is an integrated structure, built-in variable frequency power supply module, and the output power supply is continuously variable frequency adjustable. The frequency of 45-55Hz can be switched for measurement, and there are several groups of double frequency conversion for choice,and the built-in high-speed processor core adopts high-end digital filtering technology, which effectively avoids the interference of the power frequency electric field to the test, and fundamentally solves the problem of accurate measurement under strong electric field interference. A large number of on-site tests and user usage indicate that when the grounding grid is tested under the harsh electromagnetic environment of the running substation, the measured data of the grounding impedance tester of the special frequency ground network are accurate and repeatable. It is an ideal instrument for the measurement of the characteristic parameters of large and medium grounding grids. Ground Resistance Tester Features 1. HD color touch screen. The instrument is equipped with a high-end full-touch liquid crystal display, a large and full graphical operation interface, each process is very clear, and the operator can use it without additional professional training. The entire process can be measured with a single touch, making it an ideal smart measurement device. 2. Spare stylus pen. When the operators have dirt on their hands or dirt on the screen, the stylus pen can be used to operate the instrument. 3. Double frequency conversion,strong anti-interference ability. The instrument adopts the method of different frequency measurement, and with modern software and hardware filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable. 4. The precision of measurement is high. The basic error is only 0.005 Ω, which can be used to measure the earth network with very small earth impedance. 5. Powerful function. It can measure current stake, voltage stake, grounding grid impedance, grounding resistance, grounding conduction, soil resistivity, step voltage, touch voltage, potential gradient and so on. 6.

Diaphragm valves play a crucial role in shut-off and throttling services across diverse industries, including Chemical, Fossil Power Plants, Pharmaceutical, Mining, Nuclear Power Plants, and Water treatments. Capable of efficiently handling liquids, slurries, and vacuum/gas, these valves feature a flexible membrane, typically elastomer reinforced with metal, ensuring a secure seal. Tensioned by a stem/compressor with linear movement, the membrane contacts the body seal, effectively isolating the operating parts from the flow. This design renders diaphragm valves ideal for viscous, hazardous, abrasive, and corrosive flows, preventing contamination. Available in sizes ranging from 1/2 Inch to 14 Inch (DN15-DN350) with a CLASS 200 LB rating, they come in metals, solid plastics, rubber, and glass linings, catering to a wide range of chemical applications, including clear fluids and slurries. Their extended use extends to low-pressure and slurry fluid environments, where other valves may corrode or clog.
