The Monnit ALTA Wireless Voltage Meters are purpose-built for engineers, facilities managers, and maintenance teams who need reliable, remote voltage monitoring across electrical panels, equipment banks, and critical infrastructure. Capable of measuring voltage from 0 to 500 VAC or VDC, these compact sensors deliver real-time data without wires, so you can stay ahead of power issues, detect anomalies early, and reduce downtime. Designed for commercial environments, the ALTA meters simplify fleet-wide monitoring by connecting to Monnit gateways and the cloud, providing a scalable, easy-to-deploy solution for electrical health, energy management, and safety compliance. With AA battery power and a rugged form factor, these meters offer flexibility in mounting locations, quick installation, and continuous operation in demanding environments. Whether you’re auditing energy usage, verifying voltage integrity during maintenance, or tracking voltage fluctuations over time, Monnit ALTA Wireless Voltage Meters make it straightforward to capture precise readings and visualize trends from any connected device or sensor.

• Wireless voltage monitoring with real-time visibility: Measure 0-500 VAC/VDC and transmit readings wirelessly to your Monnit gateway. Enjoy instant visibility in the Monnit Console and dashboards, enabling proactive maintenance, faster fault isolation, and centralized energy management across multiple sites. The ALTA platform consolidates voltage data with other sensor types, giving you a unified view of electrical health alongside temperature, humidity, leak detection, and more.
• Direct measurement using device leads: The sensor measures voltage by connecting its leads to the positive and ground terminals of the device under test. This direct-lead approach provides accurate input without the need for a separate signal conditioning module. It’s ideal for monitoring panel voltages, motor drives, transformers, and critical power rails where precise voltage readings matter for safety and performance.
• Commercial AA battery powered with long life potential: The ALTA voltage meters operate on standard AA batteries, making replacement quick and cost-effective in busy facilities. The battery-powered design eliminates the need for power wiring in remote or hard-to-reach locations, preserving flexibility during installation. Depending on sampling frequency and network activity, you can expect extended operational life between battery replacements, delivering reliable data without frequent maintenance interruptions.
• Easy installation and rapid deployment: These meters are designed for straightforward installation, with simple lead connections to the device under test and minimal mounting requirements. Since there’s no external power supply required for the sensor itself, you can install multiple meters across an auditorium, data center, manufacturing line, or building distribution with minimal wiring and downtime. The result is a scalable, fast-to-deploy solution that grows with your monitoring needs.
• Integrated with Monnit’s ecosystem for alerts, history, and insights: Readings funnel into the Monnit Console, where you can configure alerts based on voltage thresholds, create custom dashboards, and review historical trends. This enables precise anomaly detection—such as undervoltage or overvoltage events—and helps verify compliance with electrical standards. You can correlate voltage data with other environmental or equipment metrics to optimize maintenance schedules, energy efficiency programs, and asset management strategies.

How to Install Monnit ALTA Wireless Voltage Meters

• Prepare and verify safety: Before starting, ensure the electrical system is de-energized according to your site safety protocols. If you’re not a licensed electrician, consult one to verify all work complies with local electrical codes and standards.
• Install the batteries: Insert two AA batteries into the sensor’s battery compartment, ensuring correct polarity. Replace the battery cover securely to protect against dust and moisture in harsher environments.
• Connect the measurement leads: Attach the sensor leads to the device under test by connecting one lead to the positive terminal and the other lead to the ground or reference terminal. Ensure solid, secure connections to minimize noise and intermittent readings.
• Mount the sensor: Place and secure the ALTA meter in a convenient, accessible location near the device being monitored. Use appropriate mounting hardware if the unit needs to be fixed, or position it in a rail or panel cavity where it won’t be disturbed by vibration or heat.
• Pair with a Monnit gateway: Use the Monnit Console to add the new sensor to your network. Follow on-screen prompts to pair the device with your gateway, assign it to a site, and configure basic parameters such as reporting interval and alert thresholds.
• Configure monitoring and alerts: Set voltage thresholds that reflect safe operating ranges for your equipment. Create dashboards and automated alerts (email or SMS) so you’re notified immediately of undervoltage, overvoltage, or sensor connectivity issues.
• Test and validate: Validate readings by comparing against a calibrated reference or a known voltage source. Confirm that data are consistently transmitted and displayed in the Monnit Console, and that alerts trigger as expected.
