Trumeter APM Series Digital Voltmeter AC/DC, LCD Display 4-Digits 1% Accuracy, 68 mm Cutout APM-VOLT-APO

Trumeter APM-VOLT-APO is an advanced digital voltmeter designed for precise measurement of AC and DC mains voltage in industrial and commercial control panels and power supply applications. It features a large 4-digit LCD display with 1% accuracy and an eye-catching 40-segment bar graph providing analog-style readability combined with the benefits of digital precision.

The meter automatically detects AC or DC inputs and supports voltage measurement up to 600V. Its dynamic backlight changes colour based on measured values to give immediate condition feedback, enhancing operational awareness in varying lighting environments. The device is highly customizable using the free APM configuration software, allowing users to set scale ranges, configure up to 10 alarm setpoints, adjust alarm delays, and customize messaging and colour schemes to suit their needs.

Equipped with two independent outputs, the voltmeter can simultaneously provide digital open collector outputs or analogue 4-20mA signals to interface with other control and monitoring devices. The starburst display area effectively conveys alarm information and messages for operational transparency.

The robust design includes an IP65 rated enclosure that protects against dust and jets of water, making it suitable for harsh industrial environments. It operates reliably across a temperature range from -10°C to 60°C, supporting global industrial standards including CE, IEC 61010-1, IEC 61326-1, IEC 61000-4 series, CISPR-11, and EN ISO 17050-1:2010.

Manufactured in Malaysia, the Trumeter APM voltmeter is an ideal instrument for industrial process control, electrical automation, HVAC systems, and laboratory instrumentation. Combining high accuracy, configurable features, and remote monitoring capability via Trumeter Cloud when used with the IoT Gateway, it empowers users with enhanced control and data insight.

Measures AC and DC voltages up to 600V accurately within 1% tolerance. Large 4-digit high contrast LCD display with wide viewing angle and 85mm digits. Dynamic colour-changing backlight provides immediate visual feedback.
