Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Laboratory Instruments. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The DDF-2000A is an automatic laboratory analyzer for evaluating key dielectric properties of insulating liquids, including transformer oil. Its supported measurement functions cover dielectric dissipation factor (tan delta), relative permittivity, capacitance and DC volume resistivity.
Listed test standards are ASTM D924 and ASTM D1169. The integrated instrument combines a three-electrode oil vessel, temperature control, temperature sensing, a dielectric-loss test bridge, AC test power, a standard capacitor, a high-resistance meter and a DC high-voltage source.
Microcomputer control automates heating, temperature regulation, voltage increase, data sampling, calculation, display, printing and result storage. A 7-inch color touchscreen provides the operating interface.
Published measuring ranges are 5–200 pF for capacitance, 1.000–30.000 for relative permittivity, 0.00001–100 for dielectric loss factor and 2.5 MΩ·m–20 TΩ·m for DC resistivity. The specified temperature range is 0–125 °C.
AC experimental voltage is continuously adjustable from 0 to 2200 V at 50 Hz, while DC test voltage is continuously adjustable from 0 to 500 V. The three-electrode vessel has a stated 2 mm electrode spacing. A medium-frequency induction heater and PID temperature controller are used for .
The instrument also provides blank calibration, automatic saving of calibration data, a real-time clock, ambient-temperature display and storage for up to 100 groups of results. Protection functions are described for overvoltage, overcurrent, high-voltage short circuit and temperature-sensor faults.
USB/RS232 connectivity or wireless transmission is listed as optional. Before procurement, buyers should confirm the exact supplied configuration, required mains frequency and voltage, included printer and accessories, communications options, supported test method implementation and calibration documentation.
Buyers should also request confirmation of measurement performance under their intended oil type, temperature program and laboratory quality procedures.
No specific certification is established by the available product facts, so any regulatory, accreditation or traceable-calibration requirement should be verified before ordering.
