UNI-T UT505B-Insulation Resistance Tester-Handheld
€267.00 excl. VAT
Handheld insulation tester with five test voltages from 50 V to 1000 V, measuring insulation resistance up to 200 GΩ in line with IEC 61557. Timed dielectric absorption ratio (DAR) and polarisation index (PI) modes, automatic discharge and a 99-set memory speed up routine testing. True RMS functions also cover AC/DC voltage, capacitance, frequency and leakage current.

Overview
The UNI-T UT505B is a handheld insulation resistance tester for commissioning and maintenance work on electrical installations, motors, transformers, cables and photovoltaic systems. Five test voltages from 50 V to 1000 V cover sensitive control wiring through to 1000 V industrial equipment, and the meter resolves insulation resistance up to 200 GΩ.
Timed test modes calculate the dielectric absorption ratio (DAR) and polarisation index (PI) automatically; the tester discharges the device under test after each measurement, and up to 99 results can be stored on board. It complies with IEC 61557 parts 1, 2 and 4 (2007) and doubles as a true root mean square (RMS) meter for AC/DC voltage, resistance, capacitance, frequency and leakage current.
Key features
- Five test voltages (50 V, 100 V, 250 V, 500 V and 1000 V), adjustable in 10 % steps from 50 % to 120 % of the selected range
- Insulation resistance measurement up to 200 GΩ on the 1000 V range
- Timed measurements including dielectric absorption ratio (DAR) and polarisation index (PI)
- Automatic discharge of the device under test after every insulation measurement
- High-voltage output alarm and automatic fuse self-check
- True root mean square (RMS) measurement of AC and DC voltage to 600 V, plus resistance, capacitance, frequency and leakage current
- 6000-count backlit display with analogue bar graph
- Memory for 99 measurement sets with data hold and comparison mode
- Automatic power-off; CE, UKCA and ETL certified
