Suitable for various applications, this user-friendly thermal camera is fast and accurate for detecting leaks, identifying overheated connections, locating thermal bridges, and detecting structural defects. In addition, this camera is equipped with the IFOV warner and ScaleAssist functions.
Features
- Infrared resolution 160 x 120 pixels with SuperResolution technology 320 x 240 pixels
- Thermal sensitivity (NETD) of <0.1°C (0.18°F) (100 mK)
- Automatic detection of hot and cold spots
- ScaleAssist for obtaining comparable images in building thermography
- IFOV warner: the distance to the measured object/measurement point size is determined and the measurement point is displayed on the thermal image, helping to avoid measurement errors since the camera shows exactly what can be measured
- Excellent image quality thanks to high resolution: 19,200 temperature measurement points ensure precise thermography
- Display of temperature differences starting from 0.1°C (32.18°F)
- Critical temperature conditions are displayed directly via automatic recognition of hot and cold spots
- Professional software for image evaluation on PC
- Ability to save thermal images in JPEG format
Applications
Detect leaks, identify overheated connections, locate thermal bridges, or detect structural defects with this thermal camera ideal for daily maintenance and installation work in trade and industry. It enables quick quality control and ensures reliable production monitoring.
Detection of structural defects and construction quality control
Analysis with this thermal camera is a quick and efficient method for detecting potential structural defects. It is also ideal for providing proof of the quality and proper execution of construction measures. Heat loss, moisture, and lack of airtightness in a building are visible on the thermal image. It allows detection of thermal insulation defects and structural damage — all without contact! The ScaleAssist function, which automatically ensures optimal adjustment of the thermal image scale, guarantees objectively comparable thermal images and makes it easier than ever to correctly evaluate structural defects and thermal bridges. Checking the airtightness of windows and doors is one of the typical applications for the thermal camera.
Simple verification of heating and installation systems
Easy and intuitive to use, it is ideal for quickly and reliably checking heating, ventilation, and air conditioning systems (HVAC/R). A simple glance with this thermal camera is enough to discover irregularities in temperature distribution, making it easy to locate blocked radiators and leaks. Typical applications for this thermal camera:
- Radiator inspection for detecting sludge buildup
- Leak location
- Measurement of supply and return temperatures
- Tracing the path of heating loops in a radiant floor heating system
Searching for a broken pipe
In case of suspected pipe rupture, the only solution often involves opening large sections of walls or floors. This thermal camera helps reduce damage and costs, as it precisely locates leaks in underfloor heating systems and other inaccessible pipes. This prevents unnecessary opening of walls and floors and significantly reduces repair costs.
