Suitable for
Professional building inspection and diagnostics
Water damage restoration and assessment
Locating hidden moisture behind walls and floors
HVAC system monitoring and troubleshooting
The device may not be suitable for general consumer DIY tasks where advanced thermal imaging and specialized environmental calculations are unnecessary. It is also not designed for continuous high-temperature industrial process monitoring beyond its specified operational range.
Key specifications
Thermal image resolution of 160x120 pixels
2.8-inch QVGA TFT graphical display
Integrated non-invasive pinless moisture sensor and external pin probe
Calculated parameters including dew point, vapor pressure, and mixing ratio
Rechargeable Li-Ion battery with up to 16 hours of continuous runtime
Internal memory capacity for up to 15000 images
To operate the instrument, power on the unit using the integrated rechargeable battery and select the desired measurement mode via the intuitive user interface. Use the pinless sensor for fast surface scanning or attach the external pin probe for precise material measurements. Align the integrated laser pointer to target the exact source of thermal anomalies, and capture images or environmental data as needed. Review data directly on the digital display or transfer files to a mobile device for detailed report generation.
What to consider before purchase
Verify that the measurement ranges for temperature and moisture align with your specific professional requirements
Ensure compatibility with your current reporting workflows and mobile device applications
Consider the need for optional specialized moisture probes depending on the materials you inspect
