Explore our range of precision voltage data loggers, engineered to deliver dependable, long‑term DC voltage measurement and logging across a broad spectrum of applications. Ideal for industrial testing, energy audits, research labs and regulated environments, our solutions deliver accurate insights you can trust.
Our range focuses on DC voltage data loggers and recorders — from compact USB loggers to wireless and multi-channel systems. For combined voltage and current logging and power/energy data, see our multi-parameter loggers below; for AC mains work, talk to our team about the right clamp or AC-capable option.
A voltage data logger is a compact electronic instrument that measures and records voltage levels over time. By connecting the logger directly to a circuit, battery pack, solar panel, or power supply, you can build a complete time-stamped record of voltage fluctuations — data that is essential for diagnostics, compliance testing, and preventive maintenance.
DC voltage data loggers are most commonly used for monitoring battery health and discharge cycles, recording the output of solar photovoltaic systems, logging signals process sensors, and validating power supply performance in industrial environments.

Engineers use a voltage data logger (or voltage recorder) to capture battery and solar bank voltage, monitor mains/supply quality, validate DC power supplies and sensor signals, and record 3-phase and multi-channel installations — building a time-stamped record you can download to CSV or PDF.
Choose by voltage range (millivolts to high-voltage inputs), channel count (single to 16-channel), and connectivity (USB download, Bluetooth, NB-IoT or wireless telemetry). We stock MadgeTech (Volt101A, VoltX, RFVolt2000A wireless), COMET (U5841 four-channel, M1300-series multi-loggers, MS-series monitoring systems) and EFENTO 0–10 V interfaces — with local stock, calibration and support across Australia.
Our core range is built around DC voltage data loggers that record supply rails, battery banks, sensor outputs and control signals over time. Compact USB models like the MadgeTech Volt101A suit single-channel work, while the multi-channel VoltX and COMET U5841 / U0541 capture several 0–10 V inputs at once. Ranges run from millivolts up to higher DC inputs, with sampling from one second to several minutes. Deploy the logger, then download a time-stamped record to CSV or PDF for analysis.
Need power as well as voltage? A voltage and current logger records both parameters together, so you can derive watts and watt-hours — essential for energy audits, solar arrays and battery systems. Multi-channel COMET loggers and monitoring systems can capture voltage alongside current and other analogue inputs on a single system, and they pair naturally with the units on our Current Data Loggers page. Choose the channel count and input mix your installation needs.
High accuracy & resolution – Precise readings down to microvolt resolutions with stable calibrated performance.
Flexible recording modes – Choose between configurable reading intervals (from 4 Hz to once per day) and data logging modes (cyclic or non‑cyclic).
Scalable options – Single‑channel compact designs, high‑channel VoltX systems for simultaneous multi‑point logging, wireless or GSM connectivity.
Software & cloud ready – Full MadgeTech 4 and COMET Cloud integration for easy configuration, data access, alarms, and analytics.
Robust and compliant – Rugged enclosures rated for typical industrial ambient conditions, with support for ISO‑certified calibration.
Our voltage loggers are trusted across regulated industries including medical and pharmaceutical, food and beverage, oil and gas, mining, and transport.

A voltage data logger is a device that automatically measures and records electrical voltage at set intervals and stores the readings in memory. You deploy it, then download a time-stamped graph of voltage over hours, days or months — ideal for battery and solar monitoring, supply-quality checks, and validating equipment.
They are essentially the same thing — 'voltage recorder' is the traditional term and 'voltage data logger' the modern one. Both continuously record voltage unattended, unlike a multimeter which only shows an instantaneous reading.
Our core range is built for DC voltage (battery, solar, DC supplies and sensor signals), with ranges from millivolts up to high-voltage inputs. If you need to log AC mains voltage, contact our team — we can advise on AC-capable or clamp-based options to suit the job.
Yes. Several models log voltage and current simultaneously so you can calculate power (watts) and energy (watt-hours) — useful for energy audits and solar/battery systems. Multi-channel COMET loggers and MadgeTech multi-parameter units cover this.
Match four things: (1) voltage range and AC vs DC; (2) number of channels (single up to 16); (3) connectivity — USB download, Bluetooth, NB-IoT or wireless telemetry; and (4) environment (portable, rugged or rack-mounted). Our Australian team can recommend a model for your application.
Both. USB loggers (e.g. MadgeTech Volt101A) are downloaded to a PC; wireless models (MadgeTech RFVolt2000A, COMET IoT and EFENTO NB-IoT/Bluetooth interfaces) stream readings to software or the cloud for remote monitoring.
Every logger includes configuration and download software, and many offer cloud or app access. You set the sampling rate and range, deploy the logger, then export a time-stamped report to CSV or PDF, or view it in your monitoring platform.
Yes. Pacific Sensor Technologies holds local stock, ships Australia-wide, and provides local calibration, configuration help and technical support — so advice and service don't depend on overseas turnaround.
