JY6611S Transformer oil breakdown tester

  • Product description: 1. Never crash 2. High testing precision 3. New type oil cup 4. Complete protection system:

JY6611S transformer oil breakdown tester adopts completely new electromagnetic compatibility concept(EMC) which designed to avoid tester crash accident during testing, and also can still work well in high magnetic field.

JY6611S also use advanced  voltage breakdown control technology which will keep breakdown energy in a very low level,that will avoid pollution to oil sample during testing and make sure the test result are accurate and reliable.

1. Never crash:
JY6611S adopts electromagnetism compatibility(EMC) to avoid tester crash in test process. The instrument can work well in high-intensity electromagnetic environment
2. High precision:
JY6611S adopts completely new breakdown voltage control technology to make the breakdown discharge energy to the lowest,which avoid oil sample pollution during test process and make test results reliable and accurate.
3. New type oil cup:
JY6611S oil cup is made by new material with high strength and long service life to avoid fragile and leakage problem during testing.
4. Complete protection system:
JY6611S has a variety of  protection devices which will make sure the safety of operator and tester itself in accident like inferior oil breakdown  and empty cup breakdown.

High performance of MPU (microprocessor) can provide high precise data and fast calculation.

Oil test cup made from advanced material which is high intensity with long working life.

Thermosensitive printer provide fast and clear tested value printing.
