  • Product Introduction

    Uses and applications:
    ML-72 series of meters is a direct imitation of power measurement display instruments, measuring DC current and voltage, AC current and voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-power measurements. It has been widely used in a variety of AC and DC transmission and distribution systems, power control panels and other electrical devices, in the industries of maritime shipping, rail transport, chemical flameproof, low voltage equipment, construction equipment, generators, machinery equipment, etc. Being able to make electrical measurement and non-power measurement, it is a high-end instrument applied in general environmental conditions.

    Standards and certifications:
    Production Standard: GB/T7676-1998 Safety Performance Specification: GB4793
    Dial Scale Design Specification: Germany Standard DIN43790
    Dial Pointer Design Specification: Germany Standard DIN43790
    Meter Appearance Production Standard: GB/T1242
    Meter Opening Size Production Standard: IEC61554
    International Security Certification: CE

    Unless specified, the meter is usually installed in a vertical position. Other installation positions such as horizontal and inclined position can be installed according to the customer’s requirements. The corresponding level of accuracy is only valid to the regulated installation position. The meter has two kinds of instruction angles: right angle 90°and wide angle 250°.

    Accuracy level:
    AC and DC voltmeter and ammeter to the level of 1.5 or 2.5, power meter to the level of 2.5, frequency meter to the level of 2.5, and power factor meter to the level of 2.5.
