Introducing the New testo 862 Thermal Imagers: Compact Tools for Smarter Inspections

When temperature differences reveal problems that cannot be seen with the naked eye, having the right thermal imaging cameracan make inspections faster and easier.

The new testo 862 thermal imager combines sharp thermal imaging, smart diagnostic functions and a compact, rugged design to help professionals identify potential issues across HVAC/R, heating, plumbing, electrical, mechanical and building applications. Available in two models, the testo 862-1 and testo 862-2, the range provides a practical thermal imaging solution for everyday field inspections.

Why Use a Thermal Imaging Camera?

Traditional inspection methods can require multiple measurements and visual checks to identify a potential problem. A thermal imaging camera provides another layer of information by showing temperature patterns across a surface.

This can help professionals identify unusual heat distribution, hot or cold spots and temperature differences that may indicate an area requiring further investigation.

The testo 862 is designed to make this process straightforward, with automatic diagnostic functions that help users quickly interpret thermal images and identify potential issues.

Meet the testo 862 Thermal Imager

The testo 862 is a pocket-sized thermal imaging camera designed for quick and practical inspections. Its compact design makes it easy to carry between jobs, while its thermal imaging capabilities provide detailed information directly on the device.

Both models feature thermal sensitivity of <50 mK at +25°C, while Fusion mode combines thermal and visual information to provide additional context when interpreting an image.

The range includes:

testo 862-1 – 160 × 120 Pixel Thermal Imager

The testo 862-1 provides a 160 × 120 pixel infrared resolution, making it a practical option for everyday thermal inspections and quick spot checks.

It includes smart functions such as automatic hot and cold spot detection, Delta T calculation, DeltaHeat, alarms and intelligent mould analysis.

testo 862-2 – 256 × 192 Pixel Thermal Imager

For inspections where additional thermal image detail is useful, the testo 862-2 provides a higher 256 × 192 pixel infrared resolution.

Along with its higher resolution, it offers the same range of smart diagnostic functions, including automatic Delta T calculation, DeltaHeat, hot/cold spot detection, alarms and intelligent mould analysis.

Smart Diagnostic Functions for Faster Inspections

One of the key advantages of the testo 862 range is that it goes beyond simply displaying a thermal image.

Automatic Hot & Cold Spot Detection

The camera can automatically identify hot and cold spots within the thermal image, helping users quickly focus on areas that may require attention.

Automatic Delta T Calculation

Delta T helps users analyze the temperature difference between points directly within the thermal image, making comparisons quicker during inspections.

DeltaHeat Mode

For heating applications, DeltaHeat provides diagnostic information when assessing radiator performance. Temperature distribution and uneven heating patterns can be visualized quickly, helping identify potential issues that require further investigation.

Intelligent Mould Analysis

The testo 862 can work with the testo 605i thermohygrometer to provide additional information for identifying potential mould-risk areas.

Designed for HVAC/R, Electrical and Building Inspections

The testo 862 can be used across a wide range of professional applications, including:

HVAC/R inspections
Identify unusual temperature patterns in heating, ventilation, air conditioning and refrigeration systems.

Heating and plumbing
Visualize heat distribution and investigate potential issues in heating systems and plumbing applications.

Electrical inspections
Thermal imaging can help identify unusual heat patterns around electrical components that may require further inspection.

Mechanical maintenance
Inspect equipment and components for abnormal temperature differences during maintenance checks.

Building inspections
Thermal imaging can help identify temperature variations and areas that may warrant closer investigation.

Built for Everyday Field Work

A professional thermal camera needs to be practical as well as capable.

The testo 862 features a smartphone-style interface designed for intuitive operation, allowing users to navigate the camera and review images without a complicated workflow.

It also features IP54 protection and is designed to withstand drops from up to 1.5 metres, making it suitable for demanding everyday field use.

The camera can also connect wirelessly with compatible Testo instruments, including the testo 605i thermohygrometer and testo 770-3 clamp meter, providing additional measurement information for inspections.

Professional Thermal Imaging Without the Complicated Workflow

The testo 862 range brings together thermal imaging, smart diagnostics and an easy-to-use interface in a compact instrument.

Whether you're performing HVAC/R maintenance, electrical inspections, building checks or mechanical troubleshooting, the testo 862 provides a practical way to visualize temperature differences and investigate potential problems.

With two models available, you can choose between the 160 × 120 pixel testo 862-1 and the higher-resolution 256 × 192 pixel testo 862-2, depending on the level of thermal detail required for your applications.
