LFY-405D Automatic digital fiber specific resistance meter

Main Purpose

This instrument is suitable for the latest GB/T 14342-2015 national standard, and can measure the specific resistance of various chemical fibers.  It is one of the important instruments for determining the spinnability of chemical fibers. It has the advantages of accurate, stable, rapid, and easy to use and operate.  It is suitable for the determination of the specific resistance of chemical fibers in scientific research, fiber inspection, chemical fiber production plants and user factories and other departments.

The instrument adopts touch screen operation and automatic test device, and the test data is accurate and reliable.

Technical Index

1. Measurement range of fiber specific resistance: (equivalent resistance value) 100~10¹⁴Ω, with a test sample weight of 15±0.1g for each test.

2. Basic error of the instrument: ±5% for resistances ≤10¹²Ω; ±20% for resistances >10¹²Ω.

3. The instrument should be used in an environment free from corrosive gases and strong electromagnetic field interference.

4. The instrument should be calibrated under standard environmental conditions with a temperature of 20℃±2℃ and a relative humidity of 65±10%.

5. The working power supply is AC 220±10% 50Hz.

6. The instrument's test voltage is divided into two levels: 1V and 100V, with a voltage deviation of less than ±3%. The measurement range when the test voltage is 1V is 10Ω to 10⁷Ω; when the test voltage is 100V, the measurement range is 10⁶Ω to 10¹⁴Ω; the range automatically switches.

7. The instrument can operate continuously for 24 hours.

8. Industrial-grade 7-inch touch screen.

9. Both staple fiber and filament can be measured.

10. Test results can be queried, including resistance, volume specific resistance, and mass specific resistance. The last test result is retained after power off.

11. Equipped with 8 sets of preset parameters

12. It has fiber density for 10 sets of samples, with customizable special samples, and the fiber density can be set.

13. Calibrate the resistance in different ranges to ensure accuracy.

14. It has the function of printing test reports.

15. It features a U-disk export function, allowing for permanent storage on a computer.

16. Computer file format conversion and printing functions.

17. Multi-level password permissions.

18. Dimensions: 320×400×150 mm.

19. Weight: 12 kg.
