Darui Electric recommends：
Dielectric Loss TesterBuilt-in high-voltage bridge, variable frequency power supply, step-up transformer and standard capacitor and other related components, capable of independently and automatically completing dielectric loss and capacitance measurement under 10KV. Features multiple measurement modes, with selectable forward/reverse connection, internal/external standard capacitors, CVT measurement (external step-up transformer), and internal/external test voltage for measurement. Large screen Chinese prompt operation, easy to use. Good performance, high precision, microcontroller controlled, Chinese display menu prompts, fully automatic test process, with anti-misoperation and anti-voltage rise functions.
Dielectric Loss TesterFunction Introduction:
1. Detection Items: Can quickly detect formaldehyde, sodium formaldehyde sulfoxylate, sulfur dioxide, nitrite, hydrogen peroxide, borax, pesticide residues in various foods, and protein content in milk and dairy products. The instrument reserves program and ports for other detection items, allowing convenient independent addition of detection items based on future needs.
2. Detection Channels: ≥12 detection channels, capable of testing multiple samples simultaneously, with each sample independently controlled by the program without mutual interference.
3. Display Mode: ≥8-inch LCD touch screen display, user-friendly Chinese operating interface, intuitive and simple readings.
4. Equipped with embedded thermal printer, supporting manual or automatic printing, with results printed within three minutes.
5. Light source uses imported ultra-bright LEDs, high precision, strong stability, controllable light source, can turn off unused light sources for lower power consumption.
6. Uses USB 2.0 interface design, convenient for data storage and transfer, can connect directly to computer at any time, and can control the instrument via computer. Enables data query, browsing, analysis, statistics, printing, etc.
OilDielectric Loss TesterSafety Precautions During Testing:
1. The oil dielectric loss tester must be reliably grounded, otherwise the instrument will alarm and will not enter the main menu.
2. Before taking the oil cup from or placing it on the instrument, be sure to turn off the power.
3. After installing the oil cup, first test the empty cup. The capacitance value should be 60±3pF with dielectric loss less than 0.005%; if the capacitance value exceeds 62, reinstall; if dielectric loss is unqualified, reclean the oil cup.
4. Since new oil cups may have dust or cloth debris, after installing a new oil cup, rinse it three times with sample oil (add sample oil, rotate the inner electrode up/down/left/right, then pour out). Heating improves the cleaning effect.
