    GD-875/877 infrared camera uses 25μm 160*120 detector, temperature measurement range -20℃–+ 350, 3.5inch TFT LCD screen.

     

    Application

     

    Preventive maintenance

    • Power industry: Power line and power facility thermal state checking;     fault and defect diagnosis.
    • Electrical system: Pre-identify before the circuit overload occurs
    • Mechanical system: Reduce downtime and avoid catastrophic failure.

    Construction science

    • Roof: Quick identification of water penetration problems.
    • Structure: Commercial and residential energy audits.
    • Moisture detection: Determine root cause of moisture and mildew.
    • Evaluation: Evaluate remedial measures to ensure that the area is completely dry.
