ETCR3490B High Voltage Insulation Resistance Tester

The ETCR3490 series high-voltage insulation resistance tester, also known as a megohmmeter or insulation resistance tester, is used for testing insulation resistance. This instrument is a high-performance digital instrument with functions such as LCD large screen with backlight display, data retention, automatic discharge, and automatic shutdown. The instrument has testing timing and voltage monitoring functions. When the circuit voltage is greater than 36V, the instrument will prohibit testing to protect the safety of the tested object and personnel. The instrument functions are easy to operate, with insulation resistance value, testing time, and output voltage displayed on the same screen. It also has absorption ratio, polarization index testing, AC voltage, and DC voltage testing functions.

The ETCR3490 series high-voltage insulation resistance tester has a beautiful appearance, wide range, high accuracy, high resolution, convenient operation, easy portability, accuracy and reliability, stable performance, and strong anti-interference ability. And it has earthquake resistant, dust-proof, and moisture-proof structures, making it a commonly used instrument in telecommunications, power, meteorology, computer rooms, oil fields, mechanical and electrical installation and maintenance, as well as industrial enterprises that use electricity as industrial power or energy. Suitable for measuring the resistance values of various insulation materials and the insulation resistance of transformers, motors, and electrical equipment.

Product features

1. The insulation resistance value, test time, and output voltage test data are displayed on the same screen. Testing operations and querying historical records are very convenient.

2. Efficient strong anti-interference technology, with stable testing capability in scenarios with large distributed capacitance (such as long cables) and strong electromagnetic interference environments (such as substations).

3. * Measurement indicators: Insulation resistance (IR), polarization index (PI), absorption ratio (DAR), AC/DC voltage (V).

4. Automatic discharge function, which automatically and quickly releases the charged charge of the tested object after testing, without the need for an external discharge circuit.

5. Large capacity test record storage, test records can be directly browsed and analyzed on this instrument. It can automatically store a total of 600 sets of real-time test data with test dates and timing.

6. USB communication upload function, recording data can be uploaded to the computer for storage, data statistics and analysis.

7. Bluetooth communication function, which can upload test results to the mobile phone.
