  • INQUIRY

JYL Contact resistance tester is a new generation of micro-resistance tester based on modern industrial design concept. With built-in lithium battery, no AC power supply, especially suitable for field use. The "four-wire" current and voltage measurement method can satisfy the measurement of micro resistance such as high-voltage switch, circuit breaker, GIS cabinet, cooper bar, cable connection,relay metal contact and so on.

Use aluminum shell heat dissipation to reduce heat dissipation time, and prolong product service life. Long life tapered connector is used for current extraction, which is firm and reliable. Epoxy resin encapsulation for sensitive circuits to improves the moisture resistance of the circuit.

JYL is portable, efficient, accurate and of fast test speed. It is an ideal instrument for power generation, transmission, substation, industrial and mining enterprises and other loop measurement.

Functions:

1. With built-in lithium battery(12V/5.2AH,Charging time is about 3 hours using special charger JS-042203(DC4.2V/2A*3 sets)), not need AC power supply. The instrument is suitable for field use.

2. The output current is above 100A.

3. The shell has the function of insulation, sealing, anticreep, anti-wind, and anti-sand.

4. The soft rubber at the corners protects the instrument effectively.

5. Anti-power frequency interference. The instrument can be used in 1000kV substations.

6. With 5.6 inch color touch screen. The instrument can be used indoor and outdoor.

7. With mechanical key for "run/stop".

8. With the function of monitoring and protecting the Battery power and the temperature of the instrument.

9. 100A tapered connector is used for current extraction.

10.With " flash disk" interface for exporting data.

11.With data storage function,it can store 100 sets of data.

12.With function of automatic shutdown: shutdown without operation exceeding 5 minutes.

13. With Bluetooth communication function.
