 Product Introduction

Microhmmeter also known as DC resistance tester, DC low value resistance tester. The tester adopts microprocessor technology and use precise 4-wire method to testing so that the result is accurate and reliable. It mainly used to measure transformer winding resistance, earth continuity resistance, cable conductor resistance; contact resistance of switches, connectors and relays; metal riveting resistance; winding resistance of coil, motor, transformer; connection resistance between metal components; welding point resistance ; battery parallel connection resistance; and wire length measurement & calculation, etc. The tester shell adopts a waterproof protective case, which is anti-collision, anti-drop, waterproof (protection level IP65), sturdy, safe and durable. The tester also equipped with a large-capacity rechargeable lithium battery pack, which is especially suitable for use in outdoor construction sites. The tester widely used in building quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, marine locomotive factories, etc.
The tester has two measurement modes: automatic and manual. In the automatic measurement mode, the tester will automatically select the measurement range and test current gear.  In the manual measurement mode, users can choose the measurement range and current gear by themselves, meeting the requirements of different occasions for users. The instrument also has clock function, alarm function, automatic shutdown function, etc.
it consists of host, test wires, charger, USB communication cable, etc. The tester adopt with a 5-inch touch color screen. It offers two operation modes: touch screen and buttons. The test gear, test resistance, and test current are all displayed on the same screen. The tester has bluetooth communication function, which can view the test results on the mobile phone after installing the APP, and particularly convenient for using on-site. The tester can store 1000 groups of data, connected to the computer through the USB interface and monitoring software. The monitoring software has the functions of reading, viewing, saving, reporting, and printing historical data etc.
