Ermenrich Zing TC21 Digital Multimeter is a multifunctional device for testing and measuring the parameters of electrical networks of various levels of complexity. It is designed specifically for professional use and can meet the needs of the electrician, engineer, and maintenance technician. In addition to the basic voltmeter, ammeter, and ohmmeter functions, there are frequency, capacitance, duty cycle, and temperature meters. The multimeter is a True RMS instrument, i.e., calculations are based on the True RMS method, which significantly increases the accuracy of readings.

You can select the measuring limit and operating mode manually with the rotary switch. Readings are displayed on the backlit monochrome screen. The multimeter has a flashlight for comfortable working in the dark or in low-light conditions. Additional functionality allows for all-round diagnostics of the network or equipment: locating open or short circuits, hidden wiring, or other objects of hazardous voltage, phase detection, diode test, and checking the battery performance. The multimeter also has a hold function and records the minimum and maximum values.

Powered by standard batteries. The auto-off function helps to save the battery charge when the device is not used for a long time.

Key features:

  • True RMS calculations based on the true RMS method
  • Wide range of measurement functions, including duty cycle measurement and temperature detection
  • Continuity test and diode test, NCV function for non-contact high voltage detection, battery status diagnostics, phase detector
  • Hold function, built-in flashlight
  • Manual operation with a rotary switch, battery powered

The kit includes:

  • Digital multimeter
  • Probes
  • User manual and warranty card
