Fill the gap of most imported instrument and equipment manufacturers only setting up sales points in China, with weak or no technical support, and agent distributors only specializing in sales, not professional in pre-sales technical Q&A/testing plans, and not professional in after-sales training/maintenance calibration. Our technical sales engineers all have a bachelor's degree or above and over 10 years of experience in the testing industry. With our advanced and unique business philosophy, we specialize in providing instruments and equipment, testing solutions, technical training, and maintenance and measurement services to Chinese users. We are a leading company in the East China region of ShanghaiTechnology orientedA comprehensive service provider for instruments and equipment.

Japanese HIOKI RM3548 Resistometer

High precision portable micro resistance meter capable of measuring from μ Ω to M Ω

Basic accuracy 0.02%, minimum resolution 0.1 μ Ω, maximum test current 1A

Measurable range 0.0 μ Ω (test current 1A)~3.5M Ω

Simply place the probe in contact with the object being measured to easily record up to 1000 data points

By measuring intervals, data from temperature rise experiments can be collected

Portable, suitable for maintenance and inspection of large products

Portable resistance meter suitable for low resistance measurement and inspection of large transformers and motors

A portable design that facilitates on-site maintenance and upkeep work. You can use the attached hanging rope to hang the test host around your neck and hold the clamp type test line with both hands for measurement. Powered by 8 No. 5 dry batteries, the measurement time is about 10 hours. (The usage time may vary depending on the measurement conditions)

Bias voltage correction function to reduce the impact of thermoelectric power

Thermoelectric potential refers to the potential difference generated by the connecting parts of different metals (as shown in the figure). Specifically, it will occur at the connection between the testing probe and the measured object, as well as at the connection between the measuring instrument and the measuring line. The magnitude of thermoelectric potential varies depending on the temperature of the measurement environment, and the larger the temperature difference, the greater the thermoelectric potential. The positive and negative bidirectional current of RM3548 flows through the test current, using their respective detection voltages, and has a bias voltage correction function to eliminate the influence of thermoelectric potential.

Compensation value for resistance based on changes in ambient temperature standard temperature: temperature compensation function

The temperature compensation function is to convert and display the resistance value of the tested object, such as copper wire, which may change due to temperature, as the resistance value at the set standard temperature. By using the temperature compensation function in RM3548, convert the measured voltage value Rt and the current temperature t as shown in the figure into the resistance value Rt0 at the standard temperature t0. When compensating for temperature, use temperature sensor Z2001 (standard on RM3548 host).
