Handheld Monitoring That Works Smarter, Not Harder

Still spending hours manually checking temperatures—point by point?

Infrared thermography has long been the go-to method for industrial temperature checks. But as facilities grow more complex—and the risks of downtime or fire are more costly—manual tools fall short.

They require close distance, clean surfaces, and full visibility. More importantly, they only measure one spot at a time. The result? Incomplete data, delayed responses, and missed anomalies that lead to avoidable failures.

PQSense Handheld Monitoring System transforms inspections with a smarter approach. Powered by battery-free RFID sensors, PQSense lets you instantly capture temperature data—without line of sight, without wires, and without delays.

From capacitors and lithium battery storage to ambient heat zones, inspections are no longer a burden. Just scan and go.

 

Handheld RFID Temperature Monitoring: One Scan, Multiple Sensors

The strength of PQSense lies in what it doesn’t need: no wires, no contact, no line of sight. Once sensors are installed on key hotspots—such as capacitor terminals, lithium battery modules, or environmental control points—you simply walk pass with our handheld device.

In a single click, our handheld device scans all sensors within range. Data is checked then instantly collected inside your mobile app, and uploaded to your cloud dashboard. What once took hours now takes seconds—with zero interruptions to operation.

You’re not just changing the way data is collected. You’re also achieving what infrared tools miss—blind spots,or tight spaces where trouble often are located.

How the PQSense Handheld Monitoring System Works

1. Install passive RFID sensors on hotspots—like capacitor terminals, lithium battery enclosures, or ambient temperature points. Ensure the sensor is not completely enclosed in metal casings, and have slight openings for signals to run through.

2. Use the PQSense Handheld Device to scan nearby sensors. No line of sight required.

3. The Mobile App automatically uploads all readings to the cloud, syncing with your dashboard for real-time trend charts, alerts, and reports.

Sensor Technology that Powers Smarter Handheld Monitoring

What makes PQSense truly powerful is the sensor technology at its core.

Each sensor is battery-free and wireless, meaning its battery does not require replacements nor does it require physical wires. It draws power from the handheld reader itself and transmits temperature readings via RFID, even through slight openings and without line of sight.

Unlike infrared tools that rely on surface reflections, PQSense sensors deliver direct-contact accuracy—unaffected by dust, angle, or lighting. Each one has a unique ID, allowing you to track and trend temperature behavior over time, hotspot by hotspot. Not to mention all sensors within range are collected simultaneously, unlike IR which requires spot to spot checks.

Where Handheld Monitoring Makes the Biggest Difference

PQSense is trusted across a range of high-risk, high-value environments where early warning matters most:

Lithium Battery Storage

Avoid fire hazards and ensure thermal stability in storage units with minimal effort.

High-Voltage Capacitors and Transformers

Detect contact faults and abnormal phase temperature spikes without opening panels.

Ambient Temperature Control

Track environmental zones across control rooms, server areas, or production floors—wirelessly.

In each case, PQSense delivers peace of mind through continuous, low-touch monitoring.

 

More Than Monitoring—It’s Risk Prevention

What do you gain when inspections go from reactive to real-time?

• Time — No more walking the line with a handheld IR gun.

• Accuracy — Direct, repeatable measurements across all critical points.

• Speed — Scan dozens of sensors in one motion.

• Insight & Integration — A cloud dashboard that visualizes trends, sends alerts, and keeps historical records for audits or preventive planning, all digitized.
