ET13S and ET13SPRO Handheld Thermal Imaging Camera with 192x192 IR Sensor and Temperature Measurement

The ET13S and ET13SPRO represent a combined diagnostic instrument, merging a thermal imaging camera with precise temperature measurement functionality. Designed for professional and technical use in fields such as electrical maintenance, building inspection, and mechanical diagnostics, this tool visualises heat patterns and quantifies temperature data directly. Its core component is a 192x192 pixel vanadium oxide thermal sensor, providing a detailed infrared image to help identify issues like electrical hotspots, insulation gaps, or mechanical friction. The device operates within a temperature range of 0°C to 50°C, making it suitable for various indoor and sheltered outdoor environments, and stores captured data internally for later review.

Features and Construction

This section details the core technical specifications and physical construction of the thermal imaging multimeter, outlining its capabilities and design for practical application.

Material and Build

The thermal imaging capability is driven by a vanadium oxide (VOx) microbolometer sensor, a stated material known for its use in infrared detection. The device interfaces with the user through a 2.8-inch resistive touch screen, providing control over settings and image review. Connectivity and power are managed via a built-in lithium battery and a USB Type-C port, which handles both device charging and data transfer for the internally stored files.

Size and Practical Fit

The instrument's compact form factor, measuring 134mm in length, 69mm in width, and 25mm in depth, is designed for handheld portability. This size allows it to be easily carried and manoeuvred in confined spaces typical of maintenance and inspection work. Its operational limits are defined by an operating temperature range of 0°C to 50°C and storage conditions from -20°C to 60°C, providing guidance for its care and use in different environments.

Uses and Placement

The primary application of this device is in technical diagnosis and preventive maintenance, where visualising and measuring heat is critical for safety and efficiency.

Event or Professional Use

For professional technicians, the 192x192 thermal resolution and 50.0° x 50.0° field of view allow for scanning electrical panels, switchgear, or mechanical bearings to locate abnormal heat build-up. The ability to measure specific spot temperatures from -20°C to +550°C, with tunable emissivity, supports quantitative analysis for compliance checks or fault diagnosis in industrial, HVAC, and building services contexts.

Everyday Home Use

While designed for professional-grade diagnostics, the handheld nature and clear touchscreen interface also make it accessible for advanced DIY enthusiasts or homeowners investigating issues like underfloor heating efficiency, window insulation leaks, or overheating appliances, provided the user understands the basic principles of thermal imaging and temperature measurement.

Benefits and Buying Value

The value of this instrument lies in combining two diagnostic tools into one portable unit, potentially reducing the need for multiple devices on site.

Reuse and Low Maintenance

The device is built for repeated use across multiple jobs. Its specified storage temperature range of -20°C to 60°C aids in its longevity when not in use. Maintenance primarily involves ensuring the battery is charged via the USB-C port and storing the device within its stated environmental limits to preserve sensor and electronic function.

Why Choose This Product

Choosing the ET13S/ET13SPRO is justified by its specific combination of a detailed 192x192 thermal imaging sensor with a wide-range temperature thermometer in a single handheld package. The inclusion of a 2.8-inch touchscreen for immediate feedback, along with practical 3.5MB storage and USB-C connectivity, provides a self-contained workflow for capturing and managing thermal data on the go, which can be a practical advantage for field-based technicians.
