Suitable for various applications, this user-friendly imager is quick and accurate for detecting leaks, identifying overheated connections, pinpointing thermal bridges, and detecting structural defects. Additionally, this imager features ε-Assist, IFOV warner, and the ScaleAssist function.
Features
- Infrared resolution 240 x 180 pixels with SuperResolution technology 480 x 360 pixels
- Thermal sensitivity (NETD) of <0.14°F (0.08°C) (80 mK)
- Integration of further measurement parameters via Bluetooth
- Automatic detection of hot and cold spots
- ScaleAssist for comparable images in building thermography
- Integrated 5 MP digital camera
- Recording and documentation of ambient conditions via radio probe (humidity/temperature or clamp meter)
- Thermography App enables you to write reports on site, save them online and send them by e-mail, as well as allowing you to use mobile terminal devices as a second display or for remote control
- Very good image quality due to high resolution: 43,200 temperature measuring points for precise thermography
- Detecting temperature differences from 32.14°F (0.08°C)
- Wireless communication thanks to Bluetooth
- Built-in digital camera generates a real image in parallel to the thermal image
- Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
- ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example, the thermal insulation behavior of buildings
- IFOV warner - the distance from the measurement object/measurement spot size is determined and the measurement spot is shown on the thermal image – you therefore avoid measurement errors because the camera shows you exactly what you can measure
- You can choose to save thermal images as JPEGs
- Pro software for image evaluation on the PC
ScaleAssist
Since the temperature scale and coloring of thermal images can be adapted individually, it is possible that the thermal behavior of a building, for example, can be wrongly interpreted. The ScaleAssist function solves this problem by adjusting the color distribution of the scale to the interior and exterior temperature of the measurement object and the difference between them. This ensures objectively comparable and error-free thermal images.
Thermography App
With the Thermography App, your smartphone/tablet becomes a second display, and a remote control for your thermal imager. In addition to this, you can use the App to create and send compact reports on site, and to save them online.
