The Smart Electric Sight Glasses are essential components for monitoring refrigerant status within air conditioning systems. These hermetically designed devices feature a large full-view sight glass with a moisture indicator, offering clear visibility of refrigerant conditions. Their robust construction ensures leak-proof operation, providing accurate diagnostics for systems utilizing refrigerants R22, R404A, R407C, R410A, R502, or R507. Positioned strategically in the system, these sight glasses offer invaluable insights into system performance.



  • Moisture Indicator: Provides accurate indication of moisture content in the refrigerant, aiding in system diagnosis.
  • Refrigerant Status Display: Allows for quick assessment of refrigerant status, facilitating correct diagnostics and maintenance.
  • Leak-proof Design: Ensures reliable performance and prevents refrigerant leaks, enhancing system efficiency and safety.
  • Hermetic Construction: Offers a sealed, corrosion-resistant body for long-lasting durability and optimal performance.
  • Wide-Angle Viewing Window: Provides clear visibility of refrigerant flow for ease of monitoring and diagnosis.
  • Compatibility: Compatible with a wide range of common refrigerants, making it suitable for various air conditioning systems.
  • Accurate Color Calibration: Delivers precise color indication at low parts per million (ppm) levels and higher temperatures, enhancing diagnostic accuracy.
  • Easy Installation: Features solid copper fittings and a double flare design for straightforward installation and reliable connection.
  • A/C Sight Glass Diagnosis: A/C sight glasses play a crucial role in diagnosing system malfunctions within air conditioning systems. Positioned strategically in the system, they allow technicians to observe refrigerant flow and moisture content, providing valuable insights into system performance. However, it’s important to note that sight glasses should not be the sole means of diagnosis, and caution should be exercised, especially in R134a systems where observing bubbles is normal.
