The Sonel MRU-30 is a rugged, portable tool for earth ground resistance measurements. Tests can be performed using the 2-pole, 3-pole, 4-pole, or 3-pole with current clamp methods. Additionally, the MRU-30 can perform the current clamp method using two clamps (one to generate, and one to measure current) for situations when test electrodes cant be used. The MRU-30 provides measurements of soil resistivity, continuity measurement of protective and equipotential conductors, interference voltages, and with current clamp leakage current. Robust and weatherproof (IP65) protection against ingress of dust and water Ergonomic casing small, light-weight, convenient for carrying and field work Built-in rechargeable battery can be recharged from an outlet or 12V Car socket Clear on-screen display to view results Safety alerts user of possible dangers and irregularities before and after the measurement User can use choose between measurement methods Test leads, test electrodes, and power adapter are included

The SRP-50k0-100GO calibrator is a source of high resistance, used as a standard in calibration and tests of analogue and digital insulation resistance meters. The resistance set by the calibrator can be maintained for long periods under external direct voltage up to 2500 V, provided that the current in the measuring circuit does not exceed 1.5 mA. The required resistance is set by the user using the calibrators touch keypad, or via an external PC application. The required value is set automatically thanks to the switching of a precise resistance matrix. A controlling processor calculates the required combination of resistors, ensuring adequate resistance precision. Software The SRP software is used to connect the SRP-50k0-100GO calibrator with a PC. The software is easy to use and is a useful tool for testing of devices by means of the calibrator. The calibrator connects to a computer via the USB port. Remote control of the calibrator Create and save the automatic programs to check the tested devices Set the keypad lock and time to sleep mode Change the display brightness and keypad tones Software language selection Calibrator software update from the PC via the USB interface > Each Unit Includes CD with the SRP software 1.8 m test lead with 5kV banana plugs, blue 1.8 m test lead with 5kV banana plugs, red 2.2 m shielded cable with banana plugs, black Operating manual Power cord
