Manufacturer of Mining Rail Seam Resistance Measuring Instrument

Product Introduction
The manufacturer of TPFZC mining track joint contact resistance tester (track joint resistance tester) is a specialized instrument developed and produced by Topu Electric for measuring track joint contact resistance. At present, the national security inspection department has strict requirements for the contact resistance of underground coal mine tracks, and the size of the contact resistance of the track seam directly affects the safety of coal mines. The TPFZC mining rail seam contact resistance tester is a measuring instrument used in coal mine safety production.

Technical Specifications
1. Instrument usage environment:
Environmental temperature: 5-40 ℃
Relative temperature: 20% -80%
There is no strong electromagnetic interference or corrosive gas around
2. Instrument measurement range: 1 × 10-5-2 × 103 Ω
Internally, it automatically switches between six ranges: 20m Ω, 200m Ω, 2 Ω, 20 Ω, 200 Ω, and 2K Ω.
The test currents for each range are 625mA, 625mA, 100mA, 100mA, 10mA, and 1mA, respectively.
3. Resolution: 1 × 10-5 Ω
4. Basic error: △=± 0.1% Rn+2 words
In the formula, Rn is the output information value of the measured resistor. The above △ is guaranteed in an environment of 20 ± 1 ℃ and relative humidity of 60% ± 15%.
5. Temperature additional error:
Add one basic error for every 10 ℃ deviation from the reference conditions.
6. Zui Big Display: 1999
7. Unit display: m Ω, Ω, K Ω
8. The instrument overload display shows 1999 flashing
9. Range is automatically switched
10. Working power supply: DC 9V (6 R20 dry batteries)
11. Product quality: 5Kg
