OWON HPC77+ 5000 Counts Process DC Voltage & Current Multimeter

HPC77+ Process Multimeter – Professional Handheld Process Signal Generator

The HPC77+ Process Multimeter is a compact and reliable handheld instrument designed for industrial process calibration, loop testing, and electrical maintenance. Combining accurate measurement functions with powerful signal output capabilities, the HPC77+ is an ideal tool for engineers and technicians working in automation, instrumentation, and control systems.

High-Accuracy Measurement for Industrial Applications

The HPC77+ delivers basic measurement accuracy up to 0.1% with a clear 5000-count digital display, ensuring stable and trustworthy readings in demanding environments. It supports measurement of AC/DC voltage, AC/DC current, resistance, capacitance, frequency, continuity, and diode testing, making it a versatile all-in-one process multimeter.

Built-In Process Signal Output

Unlike standard multimeters, the HPC77+ features integrated analog output functions, allowing it to act as a process signal generator. It can output DC voltage and DC current signals with up to 0.2% output accuracy, making it ideal for loop calibration and transmitter testing.
The built-in 24V loop power supply simplifies current loop testing by powering and measuring the loop simultaneously.

Designed for Real-World Process Control

To simulate actual operating conditions, the HPC77+ supports manual step output (25% / 100%), helping technicians quickly verify system response during commissioning and maintenance. The dual-purpose design reduces the need to carry separate signal sources and measurement tools.

Clear Readability and User Convenience

A backlit display and integrated flashlight ensure excellent visibility in low-light industrial environments. The Data Hold function allows measurements to be frozen for easy documentation, while auto power-off helps extend battery life during long workdays.

Portable, Safe, and Reliable

Powered by three standard AA batteries, the HPC77+ offers long operating time and easy field replacement. It complies with CAT IV 600V safety standards, providing confidence when working on high-energy electrical systems.
