The testo 868 is a compact, lightweight, advanced thermal imaging camera, suitable for many professional applications often encountered by electricians, heating engineers, facility mangers, production personnel and many more. Easy to use, affordable and perfect for everyday troubleshooting and preventative maintenance, the testo 868 provides a detailed insight into what the eye can’t always see. This makes the testo 868 a great proving tool too, for example, showing blockages that have been removed or repairs of problematic motors.
testo ScaleAssist: All models testo ε-Assist: 868 / 871 and 872 only testo thermography app: 868 / 871 and 872 only Compatible with testo 605i and 770-3: 871 and 872 only
When considering a thermal camera, thermal resolution is often the starting point. The testo 868 has 160 x 120 resolution, which is increased to 320 x 240 with testo SuperResolution software. This software enhances the thermal resolution by four times for more detailed thermal images.
The testo 868 thermal camera builds on the entry level testo 865 model, with a range of useful features including…
Increased thermal sensitivity 100mK
Choice of measuring range: -30°C to +100°C or 0 to +650°C
Integrated digital camera for ordinary digital images
Access to testo thermography app
Test e assist
Thermal sensitivity and measuring range The testo 868 is ideal for applications where more accurate temperature readings are required, or where a larger measuring range is needed, up to +650°C. The unit’s thermal sensitivity of 100mK provides the user with confidence that the camera is reporting measurements accurately and that small temperature differences are being recorded with a low margin of error. Also, auto hot / cold spot recognition allows fast pinpointing of problem areas.
Visual and thermal images The addition of a visual digital camera means a normal image is taken in parallel to the thermal image. This allows for faster troubleshooting and interpretation of images, as both the real and thermal image can be seen together.
Testo thermography app This app allows the user to quickly compile compact reports which can be saved online and easily sent via email. Images can also be streamed live to a smart device, effectively providing a second screen, allowing your customer to see exactly what you do in real time. This is ideal for when it may not be practical for the customer to be stood with the user, for example where there are high levels of noise.
Testo e assist Via the integrated digital camera, the testo 868 recognises the reference sticker (e marker) and then automatically adjusts the emissivity setting depending on the emissivity and reflected temperature. This features helps reduce inaccurate measurements as a result of emissivity caused by user error. 3 e markers are included with the Testo 868.
The testo 868 is a fixed focus thermal camera and has the same field of view as the Testo 865 at 31° x 23°, it also features testo’s Infrared Field Of View (IFOV) warner, a system that ensures the measurement spot size viewed by the user on the thermal image shows exactly what you are measuring. This greatly reduces the prospect for measurement errors.
