Detailed Introduction of ST2550 New Insulation Resistance Tester
I. Product Features
1. ST2550 can measure up to 100GΩ at 2500V, and up to 200GΩ at 5000V;
2. The rated output voltage is maintained at 20MΩ/40MΩ for ST2550, allowing the meter to accurately measure lower insulation resistance.
3. Automatically switches between high and low ranges with dual scale indication; colored scales are easy to read, and LED displays corresponding colors.
4. The whole unit adopts ABS plastic casing with portable design, featuring strong anti-interference capability, compact structure, and elegant appearance.
5. The meter uses an ultra-thin taut-band meter movement, providing strong shock resistance.
6. AC/DC dual use, built-in rechargeable battery and intelligent charging module, with high output power (Type C).
7. It is an ideal test instrument for measuring insulation resistance of transformers, instrument transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
