By OEM Update Editorial September 8, 2020 11:05 am

Thermal Imagers are the most effective tools for predictive and preventive maintenance of various industrial processes and necessary equipment performance which helps to avoid failure and losses. In the range of thermal imagers, testo 868 is one of the best in its class considering its quality, measuring performance and impressive smart functions. Its integrated digital camera ensures high resolution image quality and makes operation quicker and easier. Not only that, with this hand held easy to carry instrument the user can generate error-free and objectively comparable infrared images and execute on site reporting via testo Thermography App.

Since it is Wi-Fi enabled and equipped with smart technology, one can even use a smart phone or tablet as a second display or for remote control. Serving various day to day applications, testo 868 can identify leaks, overheated connections, overloaded machine parts, electrical anomalies, structural defects etc and are used for:

Mechanical & Electrical maintenance
In the industry where machines and equipment are continuously operating to fetch desired output, it becomes equally important to ensure their health and proper working conditions. Early identification of imminent malfunctions or defects on plants and machines is critical and same goes for electrical components and connections. Increase or difference in the surface temperature of any component can be reliably recorded in time with thermal imagers and testo 868 is the ideal instrument that is used for:
• Identify wear on machines, motors, bearings, shafts etc.
• Fast detection of Hot Spots during continuing operation
• Avoid expensive damage, downtimes and fire risks on plants and machines
•Test switching cabinets, electrical conditions or circuit boards
• Evaluate heat status in low, medium and high voltage plants.

Building Thermography
Health of a building is necessary due to various aspects. Detecting structural defects and ensuring construction quality be it due to improper heat transfer, leaks, cracks or moulds in the structure can be easily addressed with testo 868.
• Test air-tightness of windows and doors
• Locate insulation errors and cold bridges in a building shell
• Detect and visualize mould-risk areas.

HVAC system maintenance
For any facility, right from shopping malls, hospitals, exhibition centers, meeting rooms or even airports, proper checking of air circulation and heating systems and their installations is must because it directly influences human comfort and health. Facility managers are obligated to ensure healthy systems and testo 868 can assist them in various ways:
• Testing air conditioning/ventilation systems and identify irregularities in the temperature

Thermal Inspection of Solar PV plants
Solar plants are great sources of power and electricity and some serious threats can jeopardize the power output of these systems. Also, since there are so many crucial components in the PV plants like solar modules, cells, array box, diode junction box, invertors, LT panels, cables etc, it makes the maintenance of the plants compulsory and what better way than conducting thermal inspection to detect
Hotspots and localized heating due to bird drop, dust and dirt
• Hotspots and localized heating due to bird drop, dust and dirt
• Open/Short circuit in the modules and cells
• Overheating of panels or joints
• Micro-cracking and cell ruptures
• Corrosion and loose connections

Technical highlights of the testo 868
• Infrared resolution of 160 x 120 pixels and extended to 320 x 240 pixels via integrated SuperResolution technology
• Large temperature measuring range from (-) 30-degree C to (+) 650-degree C
• Smart and networked with free testo Thermography App
• Automatic hot-cold spot recognition directly displays critical temperature conditions
• The testo ɛ-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
• Pro software for image evaluation on the PC.
