Pointer DC voltmeter:
Measuring range: including different ranges from 0.5V to 600V, suitable for the measurement of various DC voltages.Application range: Widely used in machinery manufacturing,
Electrical equipment production and assembly and other fields. Specific applications include high and low voltage electrical cabinets, ships, plastic machines
Machinery, ultrasonic instruments and equipment, cleaning equipment, machines
Beds, large welders and machinery, etc.
Product model: For example, model BP-670, specially designed
The meter is used for the measurement of DC voltage. The range is
DC10V and supports 60/120Hz frequency
Pointer type AC voltmeter:
Frequency range: Specifically designed to measure 45
65Hz AC frequency with an accuracy of 1.5.
Voltage allowed fluctuation range: ±20%.
Product Model: Example BP-670 model, except straight
In addition to current voltage measurement, it also supports AC frequency measurement of 45-65Hz
Product packaging and storage:
Packing: Use thickened packing boxes and bubble bags to reduce the risk of moisture, soaking, extrusion and impact during transportation.
Storage: require neat warehouse and clean working environment to ensure product quality and service life
In summary, pointer DC voltmeters and AC voltmeters play an important role in electrical measurement, and their design and application range are targeted at specific measurement needs. By understanding the characteristics and applications of these meters, it is possible to more effectively select and use the measuring tools that are suitable for the specific needs.
