Multimeter analog BLOW 9320 — analog voltmeter up to 40 V

Analog voltmeter BLOW 9320 is a handheld instrument designed to measure and display DC voltage up to 40 V using a moving-needle indicator. The compact housing and clear scale provide an immediate visual representation of electrical potential, making the device suitable for simple voltage checks in low-voltage circuits, basic electronics work, hobby projects and educational demonstrations. The instrument does not include digital functions and relies on a mechanical pointer for readings.

Advantages

The BLOW 9320 offers a straightforward needle display that enables quick, at-a-glance voltage estimation without menus or settings. Its analog scale allows users to observe trends and fluctuations in voltage that can be less obvious on a discrete-digit display. The handheld format is portable for field checks and convenient for bench work where a simple, robust instrument is preferred. The lack of digital circuitry reduces dependence on batteries and simplifies operation.

Suitable for

• Basic voltage checks in low-voltage DC circuits
• Hobby electronics and DIY projects
• Educational demonstrations and classroom use
• Simple field inspections and troubleshooting

Key specifications

• Measurement type: DC voltage (analog needle)
• Maximum measurable voltage: 40 V
• Display: moving-needle analog scale
• Form factor: handheld, portable
• Power: no digital display or advanced electronics required

How to use

Connect the voltmeter probes to the circuit under test with correct polarity: the positive probe to the positive point and the negative probe to the reference or ground. Hold the instrument steady and read the needle position against the printed scale to determine the voltage value. Avoid applying voltages exceeding the rated maximum. Use insulated probes and observe standard electrical safety precautions when working near live circuits.

Usage recommendations

For reliable readings, ensure the instrument is mounted or held steadily and that connections are secure. When measuring unknown circuits, start from the highest expected range or confirm that the voltage does not exceed the instrument’s maximum rating. Store the voltmeter in a dry environment and avoid mechanical shocks to preserve calibration and needle movement.
