ET13S and ET13SPRO Thermal Imaging Multimeter: A 2-in-1 Tool with 192x192 Resolution and Touch Screen

The ET13S and ET13SPRO thermal imaging multimeters merge essential electrical measurement capabilities with advanced thermal imaging diagnostics into a single, compact instrument. Designed for technicians and engineers, this device provides a visual representation of temperature variances through its integrated camera, aiding in fault detection, energy audits, and preventive maintenance. The handheld form factor, clear 2.8-inch display, and straightforward controls make it a practical choice for field use where identifying thermal patterns alongside standard multimeter readings is valuable.

Features and Construction

This instrument's core functionality is built around its integrated thermal imaging system and measurement circuitry, housed in a portable chassis. The design prioritises a clear user interface and reliable data capture for diagnostic scenarios.

Material and Build

The device incorporates a vanadium oxide (VOx) microbolometer as its thermal imaging sensor, a material chosen for its sensitivity to infrared radiation. This sensor is paired with a built-in rechargeable lithium battery, providing cordless operation for use in various locations. The construction supports operation in environments from 0°C to 50°C with under 85% relative humidity (non-condensing), and it can be stored in temperatures from -20°C to 60°C.

Size and Practical Fit

The unit's dimensions are 134mm in length, 69mm in width, and 25mm in depth, creating a form factor that is designed to be held and operated with one hand. This size accommodates the 2.8-inch display, control interface, and internal components while remaining portable for carrying in a toolkit or pocket. The resistive touch screen adds to the compact design by reducing the need for multiple physical buttons.

Uses and Placement

As a combined tool, this product serves dual purposes across professional, industrial, and technical fields where temperature diagnostics and electrical measurement intersect.

Event or Professional Use

For professional electricians, HVAC technicians, or building maintenance engineers, the thermal imaging function can visually identify overheating components, circuit breakers, motor bearings, or insulation faults. The ability to measure temperatures from -20°C to +550°C and save images via the 3.5MB storage allows for documenting issues, creating reports, or comparing conditions over time. The adjustable emissivity (0.1 to 0.99) improves measurement accuracy on different surface materials.

Everyday Home Use

For the advanced DIY enthusiast or homeowner, the tool can assist in domestic energy efficiency checks, such as locating drafts, assessing insulation, or checking for hot spots in domestic fuse boxes or appliances. The multimeter functions provide standard voltage, resistance, and continuity checks for household electrical projects, making it a versatile addition to a home workshop when visual thermal data is beneficial.

Benefits and Buying Value

The primary value lies in combining two diagnostic tools, which can reduce the need to carry separate devices and streamline the troubleshooting process with correlated data.

Reuse and Low Maintenance

The instrument is designed for repeated use across multiple projects. The rechargeable lithium battery supports cordless operation, and the robust operating temperature range suits various indoor and sheltered outdoor environments. With no consumable parts aside from the battery's eventual lifecycle, the main maintenance involves basic care like keeping the sensor lens clean and storing the device within its specified temperature limits.

Why Choose This Product

This thermal imaging multimeter is chosen for its specific 192x192 sensor resolution, which provides a defined level of image detail for thermal analysis, and its integrated design that saves space in a toolkit. The inclusion of a USB Type-C port for data transfer and a touch screen interface offers modern connectivity and ease of use. It provides a concrete technical specification set, including a 50° field of view and 20Hz refresh rate, for users who require known performance parameters in a combined instrument.
