DP7160 type explosion-proof electrostatic voltmeter is a new high-performance, low-price electrostatic voltmeter (electrostatic potentiometer) which has been used by many users for more than 10 years and has been improved many times on the basis of absorbing domestic and foreign advanced electrostatic instruments. The instrument has good explosion-proof performance and the explosion-proof mark is ExiaIICT6. Can be used in various types of gases (such as gasoline, carbon disulfide, municipal gas, ethylene, acetylene, hydrogen, benzene, etc.). Ex-exposure inspection is qualified. At present, the electrostatic voltmeters at home and abroad can be divided into contact and non-contact electrostatic voltmeters according to whether they are in contact with the object under test. Since the contact type object will discharge when the contact type electrostatic voltmeter is measured, there is a danger of discharge ignition during the measurement process, so it cannot be used in dangerous places. Foreign standards prohibit the use of contact type electrostatic voltmeters in hazardous places. There are many non-contact electrostatic voltmeters at home and abroad, but some are not explosion-proof and cannot be used in explosive hazardous locations. Some probes are unreasonably designed, and the metal parts are directly exposed to the outside, and some even have no protective measures. If accidentally contact with the object to be measured during measurement, discharge may occur, which may cause an accident. Based on the research of many non-contact electrostatic voltmeters at home and abroad, we have designed a new type of probe for "anti-discharge-self-protection" and developed a BLY/EST101 explosion-proof electrostatic voltmeter. The probe of this watch is placed in the shell. The outer side of the metal probe has an insulating protective layer, which minimizes the probability of discharge and reduces the intensity of the discharge, and the meter itself is not damaged by external static electricity (such as a human touch probe). EST101 type explosion-proof electrostatic voltmeter has become the best electrostatic voltmeter at home and abroad. It has obtained the explosion-proof certificate of the relevant state departments. It can be used in any gas environment. It is suitable for danyao, pyrotechnics, petroleum, Electrostatics in the research and production of chemical, textile, paper, rubber, printing, computer and other industries. The instrument is suitable for measuring the electrostatic voltage (potential) of charged objects, such as the electrostatic potential of conductors, insulators, and human bodies. It can also measure the liquid level potential and detect the performance of anti-static products. It is widely used in the measurement of static electricity in petroleum, chemical, oil depot, fire, electronics, national defense, aerospace, natural gas, printing, textile, printing and dyeing, rubber, plastics, spraying, medicine and other scientific research, production, storage and transportation safety management departments. It is the ideal instrument for on-site static detection
