REED R5077 True RMS Digital Multimeter | NCV & Temp | 1000V

The Challenge: Too Many Meters, Not Enough Hands

Every trade professional knows the frustration. You’re halfway through troubleshooting a commercial switchboard when you realise the meter in your hand only covers half the measurements you need. Voltage and current? Sorted. But then you need temperature readings from that suspect contactor, or you want to verify capacitor health before signing off. Suddenly you’re back at the van, swapping instruments, wasting time you don’t have.

For electrical contractors juggling residential call-outs with light commercial work, and maintenance techs bouncing between HVAC systems and motor control centres, carrying multiple single-purpose meters simply isn’t practical. What’s needed is a properly specced multimeter that consolidates essential measurements into one reliable, job-site-tough package.

How the REED R5077 Solves the Problem

The R5077 earns its place in your toolkit by combining seven measurement functions into a single True RMS instrument. Beyond standard AC/DC voltage and current testing, it integrates resistance, capacitance, frequency, and Type K thermocouple temperature measurement—all accessible through an intuitive autoranging interface.

True RMS technology ensures accurate readings on the non-sinusoidal waveforms increasingly common in modern electrical systems. Variable frequency drives, LED lighting circuits, and electronic loads distort waveforms in ways that trip up average-reading meters. The R5077’s True RMS engine handles these conditions, delivering reliable measurements whether you’re testing a clean sine wave from the grid or the choppy output downstream of an inverter.

The integrated non-contact voltage detector adds another layer of practical safety. Before you touch anything, a quick sweep confirms or rules out live conductors—particularly valuable when working in panels where conductor identification isn’t always obvious.

Key Benefits & Features

True RMS Accuracy for Real-World Circuits Average-responding meters can mislead you when waveforms deviate from pure sine waves. The R5077’s True RMS circuitry provides dependable accuracy across the range of waveform types encountered in contemporary electrical and electronic systems, from VFD-fed motors to switch-mode power supplies.

Seven Functions, One Meter Voltage and current measurements span from millivolt and microamp precision through to 1000V AC/DC and 10A ranges. Resistance testing extends to 99.99MΩ, capacitance reaches 9.999mF, and frequency measurement covers 99.99Hz to 9.999MHz. The included Type K thermocouple probe enables temperature readings from -40°C to 1000°C—handy for thermal verification of connections, motor housings, and HVAC components.

Built-In Non-Contact Voltage Detection Embedded NCV functionality lets you identify energised conductors without probe contact. It’s a fast, safe preliminary check that’s become standard practice for tradies working around live switchgear.

CAT III 600V Safety Rating Certified to CAT III 600V, the R5077 meets the protection requirements for distribution-level measurements in fixed installations. That covers most residential and light commercial work Australian electricians encounter daily.

Clear 9,999-Count Display with Backlight The high-resolution LCD provides easy-to-read digits even in awkward positions, while the backlight proves its worth in dim ceiling spaces and poorly lit switchrooms.

Rugged Double-Moulded Housing Built to handle trade conditions, the reinforced housing withstands drops, bumps, and the general rough treatment tools cop in site bags and ute trays.
