With the support from numerous equipment manufacturers in the world, EMIN Vietnam possesses well-prepared calibrating instruments. EMIN Vietnam has successfully repaired and calibrated specialized equipment in Vietnam, ensuring the quickness, effectiveness and convenience for customers. Only few technical trading company in Vietnam do possess this technical capacity including EMIN Vietnam.

>> Compact VoltMeter
- Equipment used to measure current voltage, voltage measurement at two ends of details or machines, circuits. Electrical safety inspection and maintenance support. Widely used in the field of electronics, civil electricity and any related fields to use electricity.

>> Other information
VoltMeter is currently included in Multimeter to integrate measuring more factors than merely Voltage.

♦ Classification of Multimeter
Currently, the Multimeter field is divided into two categories: Electronic Multimeter and Indicator Multimeter.

Indicator Multimeter
This type of watch was born before and is gradually being replaced by electronic gauges. Its main division is the successor Gavano. This meter usually measures only the basic electrical quantities of amperage, voltage and resistance.
The measured results will be displayed using a pointer on an arc ruler. This hand multimeter may not need a power source when operating in amperage and voltage measurement mode.
If you are only using it to measure continuity or check capacitor discharge then a multimeter indicating needle is sufficient.

Electronic Multimeter
Electronic multimeter is also known as digital display multimeter. It uses active electronic components and requires a power source such as batteries. This is the most common type of multimeter right now. The result of the measurement is usually displayed on a liquid crystal display, so the meter is also known as a digital digital multimeter.
Using the electronic multimeter, users will be able to read the results accurately and quickly through the display. In addition to the common functions, the multimeter is also equipped with the following features:
+ Check circuit connection: machine beep "beep" when the resistance between 2 probe (near) is 0.
+ Display number instead of needle on the ruler.
+ Add amplifiers to measure voltage or amperage is small when the resistance is large.
+ Measure the inductance of the inductor and the capacitance of the capacitor, useful when checking and installing the circuit.
+ Check diode and transistors, useful for circuit repair.
+ Support for temperature measurement by thermocouples.
+ Average frequency measurement, audio amplification, to tune the radio circuitry. It allows to hear the signal instead of seeing it (as in an oscilloscope).
+ Low frequency oscilloscope, available in multimeters that communicate with computers.
+ Phone checker kit.
+ Automotive circuit tester.
+ Retention of measurement data (for example of voltage).

♦ Application of electric meter - multimeter in life
- Electrical application in the electronics industry
- Application in the field of research
- Application in the manufacturing sector
