Digital Ohmmeter
- Measurement range 200 Ω to 2000 Ω
- Auto-ranging
- Auto power-on/off
- Explosion-proof approved
- Leatherette case
- IP54 protection rating
The digital ohmmeter DO 200/2000.P is designed for measuring the ohmic resistance of blasting circuits during blasting operations. Measurement starts automatically upon connection of the measured resistance. Due to its circuit and structural design, it is suitable for both surface and underground use, as well as in explosive atmospheres. The package includes a leatherette case that provides protection for the input terminals against short-circuiting.
