192x192 Resolution Thermal Imaging Multimeter with Touch Screen and Wide Temperature Measurement Range

Combining thermal imaging technology with multimeter functions, this ET13S/ET13SPRO device offers a practical solution for professionals needing visual thermal data alongside electrical measurements. The 2.8-inch resistive touch screen provides control over a 192x192 pixel thermal imaging system powered by a vanadium oxide sensor. With a temperature measurement span from -20°C to +550°C and adjustable emissivity settings, it accommodates various inspection scenarios in electrical maintenance, building diagnostics, and mechanical systems monitoring where non-contact temperature assessment is valuable.

Features and Construction

This thermal imaging multimeter integrates several technical specifications into a compact housing measuring 134mm × 69mm × 25mm. The device operates within environmental conditions of 0°C to 50°C temperature and below 85% relative humidity non-condensing, with storage capability from -20°C to 60°C.

Material and Build

The core thermal sensor uses vanadium oxide (VOx) technology, a material chosen for its thermal detection properties in imaging applications. Power is supplied by a built-in lithium battery, while connectivity is handled through a USB Type-C interface. This combination supports the device's 3.5MB storage capacity for thermal images saved in BMP format.

Size and Practical Fit

With dimensions of 134mm × 69mm × 25mm, the unit provides a portable form factor suitable for fieldwork. The 2.8-inch display with 320 × 480 resolution offers clear visualization of thermal patterns and measurement data. The resistive touch screen interface allows direct interaction with the device's functions without excessive button pressing.

Uses and Placement

This instrument serves dual purposes through its thermal imaging and multimeter capabilities, addressing different professional inspection needs in a single tool.

Event or Professional Use

For electrical troubleshooting, the thermal imaging function can identify overheating components, loose connections, or circuit imbalances without physical contact. The 20Hz image capture frequency provides near-real-time thermal monitoring, while the 50.0° horizontal × 50° vertical field of view (72.1° diagonal) captures adequate area coverage for typical inspection scenarios.

Everyday Home Use

While primarily designed for technical applications, homeowners might use the device for detecting heat loss around windows and doors, identifying plumbing issues behind walls, or checking electrical panel temperatures. The automatic gain mode simplifies operation for occasional users, while the adjustable emissivity (0.1-0.99 with 0.95 default) accommodates different surface materials commonly found in residential settings.

Benefits and Buying Value

The integration of thermal imaging with multimeter functions creates practical advantages for users needing both visual thermal data and electrical measurements.

Reuse and Low Maintenance

The device's construction with a vanadium oxide sensor and lithium battery power supports repeated use across multiple projects. The USB Type-C interface facilitates both data transfer and charging, while the 3.5MB storage capacity allows keeping reference images from previous inspections. Operating within the specified temperature and humidity ranges helps maintain consistent performance.

Why Choose This Product

This thermal imaging multimeter provides a specific combination of 192x192 thermal resolution with electrical measurement capabilities in a single device. The touch screen interface differentiates it from basic thermal cameras, while the -20°C to +550°C temperature range covers common industrial and building inspection needs. For professionals requiring both thermal visualization and electrical diagnostics, this 2-in-1 approach reduces the need for separate instruments.
