【Professional-Grade 2-in-1 Electrical Tester: Multimeter & Megohmmeter】ZT-1000R is a device with both a high-precision digital multimeter and a professional insulation resistance tester (megohmmeter). If you need to measure current and voltage or detect leakage, with this multimeter you don't need to carry multiple devices, it dramatically improves your work efficiency, is the ideal tool for electricians, engineers, maintenance technicians.

【Advanced Insulation Diagnostics: DAR + PI Testing】This insulation tester supports DAR testing and PI testing in addition to traditional insulation resistance testing, enabling it to meet more specialized testing needs. Quantify insulation quality degradation and predict failures in motors, transformers, and cables – critical for preventive maintenance programs.

【A specialized Tool for Measuring Leakage】This insulation tester measures the resistance of insulating materials under high voltage. If the resistance value is higher, it indicates better insulation performance. It can also detect insulation defects: e.g. aging of the insulation, moisture, cracking, contamination or mechanical damage, which can lead to a reduction in insulation resistance and may trigger a leakage or short circuit.

【All-around Measurement, All in One】More than just a basic multimeter! It can also accurately measure AC/DC voltage, resistance, capacitance, diode on-off voltage drop, temperature (need to be adapted to the probe), frequency. It is fully functional and can help you meet all kinds of electrical diagnosis and repair challenges.

【Professional Grade Insulation Testing, 5 High Voltage Grades Available】This megohmmeter provides five standard test voltages of 50V, 100V, 250V, 500V, 1000V to meet the needs of insulation resistance safety testing in different scenarios ranging from low-voltage electronic equipment to power lines and motor windings to ensure safety at work.

【19999 Ultra High Count & Intelligent Auto-Ranging】This digital multimeter is equipped with an advanced 19999 count display that provides extremely accurate readings. Intelligent auto-range function eliminates the hassle of manually switching gears and simplifies the operation process, making measurements faster and more hassle-free, especially for complex environments.

【User-friendly Design, Long Battery Life, and Insulated Rubber Case】This 2-in-1 multimeter is equipped with a large backlit LCD screen, ensuring that you can easily view data even in low-light environments. The device has a built-in high-capacity rechargeable lithium battery (14500mAh) and uses a battery compartment to charge the lithium battery. It also supports an auto-shutdown function to effectively save power. The megohmmeter with an insulated rubber housing not only protects the device from damage caused by drops but also ensures your safety during measurements.
