Product information

Description

The Flir Systems MR277 Thermal Hygrometer and Psychrometer with Digital Square Display and Li-Ion Battery is an advanced electronic measuring tool engineered for precise indoor moisture detection and comprehensive thermal imaging analysis. Combining Infrared Guided Measurement technology with Multi-Spectral Dynamic Imaging, this device allows professionals to locate, identify, and document building envelope issues efficiently. Featuring a clear 2.8-inch digital square display and a reliable rechargeable battery power source, it serves as an all-in-one solution for accurate humidity, temperature, and moisture assessments across various demanding environments.

Advantages

This professional instrument integrates a high-performance thermal imaging sensor with advanced environmental diagnostics, enabling users to clearly visualize problem areas that are invisible to the naked eye. The inclusion of MSX technology embosses visual details onto thermal images for enhanced context and clarity. With both non-invasive pinless sensing capabilities and an external pin probe, the device accommodates rapid scanning as well as deep measurements. The field-replaceable temperature and relative humidity sensor minimizes operational downtime, while wireless connectivity options support seamless data transfer and reporting.

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

For optimal performance and longevity, store the hygrometer within recommended temperature limits, regularly check and calibrate field-replaceable sensors, and keep the optical and sensor surfaces clean from dust and debris.
