EMIN Vietnam Joint Stock Company would like to respectfully announce the holiday schedule for Southern Liberation and International Labor Day 30/4 - 1/5 to all Customers and Partners.

An analog multimeter can still be used to quickly check if a capacitor is shorted, open-circuited, or capable of charging and discharging. However, if precise capacitance measurement or an assessment of capacitor quality is required, a digital multimeter or LCR meter will yield more reliable results

By simply measuring the rotational speed (RPM) and comparing it against design specifications or historical maintenance data, engineers can detect signs of belt slippage, speed reduction, or power loss without needing to disassemble the motor

Measuring pump shaft speed helps determine the equipment's actual rotational speed (RPM), allowing for comparison against design specifications to detect issues such as belt slippage, incorrect gear ratios, abnormal motor operation, or failure to achieve the desired flow rate. Depending on operating conditions, engineers may choose a laser tachometer, a contact tachometer, or a stroboscope

RPM measurements can certainly be used to calculate conveyor belt speed (m/min) if the drum diameter is known. Learn about the calculation formula, practical examples, and how to take accurate measurements using a tachometer

To share knowledge about testing equipment and testing solutions in the electrical and energy sector, Ponovo organized a training and product presentation session at the EMIN office on July 9, 2026.
