Uni-T UT501B insulation resistance meter

The UNI-T UT501B insulation resistance meter is a digital measuring instrument designed for both electronics and electricians. It enables the measurement of high resistances up to 5 GOhm with a test voltage of 1000 V. Moreover, the meter enables the measurement of AC voltage and the measurement of small resistances. Among the additional functions, it is worth paying attention to the dielectric absorption test, polarization indexing and the zeroing function. This model meets the standards of the IECG1010 standard.

Measurement ranges:

For a test voltage of 250 V: 0 ~ 5 GOhm

• 0 ~ 99.9 MOhm ± (3% + 5)
• 100 MOhm ~ 5 GOhm ± (5% + 5)

For a test voltage of 500 V: 0 ~ 5 GOhm

• 0 ~ 99.9 MOhm ± (3% + 5)
• 100 MOhm ~ 5 GOhm ± (5% + 5)

For a test voltage of 1000 V: 0 ~ 5 GOhm

• 0 ~ 99.9 MOhm ± (3% +5)
• 100 MOhm ~ 5 GOhm ± (5% + 5)

Testing current:

• 50V (R = 50kOhm) 1mA 0% ~ 10%
• 100V (R = 100kOhm) 1mA 0% ~ 10%
