Tesko Insulation Resistance Tester TK2683A/TK2682A High Precision 1000V Electrical Equipment Milliohm Meter
The "Tesko Insulation Resistance Tester TK2683A/TK2682A" you mentioned is an industrial-grade testing device produced by Changzhou Tesco Electronics Co., Ltd. However, it is necessary to first correct a key concept for you:
These two instruments belong to the "insulation resistance tester" category, mainly used for measuring extremely high resistances at the megaohm (MΩ), gigaohm (GΩ), or even teraohm (TΩ) level, rather than the "milliohm meter" you mentioned (milliohm meters are typically used for measuring DC low resistance at the microohm level).
Based on relevant technical data, here are the core parameters and functional features of the TK2683A and TK2682A insulation resistance testers:
1. Core Parameter Comparison
Both instruments are equipped with a 4.3-inch 24-bit true color LCD screen, support Chinese and English operation interfaces, and have a basic accuracy of ±5%, but they differ in range and speed:
TK2683A (flagship high-speed type): Test voltage supports arbitrary setting from 1V to 1000V, with an extremely wide resistance measurement range of
TK2682A (standard type): Test voltage supports 10V to 1000V, with a resistance measurement range of
2. Core Functions and Technical Features
Dual Display and Capacitive Detection: Supports simultaneous dual display of insulation resistance and leakage current; equipped with a contact check function for capacitive materials (such as capacitors), requiring capacitive loads greater than 100pF.
Intelligent Sorting and Comparison: Supports programmable sequential test modes. The TK2683A supports four-level comparison (three pass levels, one fail level), while the TK2682A supports two-level comparison, making it ideal for rapid product pass rate screening on production lines.
Automation and Data Management: Built-in 20 file groups, supports U-disk data storage, automatic system firmware upgrade, and screenshot functions. Standard interfaces include RS232, USB Device/Host, and Handler, supporting SCPI and MODBUS protocols for easy integration with automated production lines.
Convenient Operation: Supports external foot switch trigger testing, freeing hands and improving batch testing efficiency.
3. Main Application Areas
This series of instruments is widely used for testing ultra-high value resistors, capacitor insulation resistance and leakage current, various dielectric insulation materials, electrical equipment, wires and cables, as well as insulation tests required by safety regulations.
💡 Selection and Procurement Suggestions
If you are evaluating these two devices, it is recommended to choose based on your actual testing needs:
Clarify the test object: If you need to test DC low resistance (such as milliohm level) of motor windings, transformers, or cables, you need Tesco's "DC resistance tester" (such as the TK2511 series); if you are testing insulation layers or withstand voltage safety, choose these two insulation testers.
Range and speed requirements: If your test objects require extremely high insulation (up to 10TΩ level) and the production line pace is fast, it is recommended to choose the TK2683A; if conventional insulation testing (within 1TΩ) is sufficient, the TK2682A offers better cost performance.
Verify after-sales qualifications: Tesco Electronics is a national high-tech enterprise, providing 2-year free warranty and free software upgrade services. When purchasing, it is recommended to request the latest factory test report from the manufacturer and confirm whether its interface protocols are compatible with your existing automation equipment.
