HK-3062DZ Automatic Volume Resistivity Tester is designed and manufactured based on “DL/T 421-2009 Determination of volume resistivity of power oils”. It adopts composite electrode cup to test the volume resistivity (Ω·m) of liquid such as insulating oil, fire-resistant oil. The LED touch screen is easy to operate. With the functions of auto-cleaning, auto-sampling, auto-temp-control, auto-voltage-increasing, auto-measurement, auto-electro-discharge, auto-heat-releasing, auto-drain, realize full process automatic control and detection without manual involvement, which can improve the working efficiency and reduce the risk of surface contamination and scratches on the electrode cup.
◆ Adopts the LED touch screen, Chinese or English are optional, easy to operate.
◆ Adopts the PID intelligent temperature control technology, which is high accuracy.
◆ High automation: With the functions of auto-cleaning, auto-sampling, auto-temp-raising, auto-voltage-increasing, auto-measurement, auto-range-switching, auto-electro-discharge, auto-heat-releasing, auto-drain, which are no human contact needed.
◆ Composite electrode cup: Dual measurement and temp control with inner and outer electrodes, which can ensure the actual temp of the oil sample.
◆ Custom pattern: The temperature, voltage-increasing time, discharge time, test times, cleaning times can be set by users.
◆ Dual cups, dual temperature, dual flow path: The insulating oil and fire-resistant oil can be tested at the same time by the instrument, which are independent and without mutual contamination. The oil cups do not need to be removed when measuring continuously.
◆ Empty cup insulation resistance: Monitor the empty cup cleanness before test.
◆ Standard calibrator (Optional): Check the measurement accuracy at any time
◆ Higher safety: With the functions of voltage-increasing and heating protection, Self-diagnostic prompt, and current-limit protection.
◆With USB port, RH-45 network port and RS-232 serial port, which can access LIMS system.
