🔍 Key Concepts

• Types of refrigerant leak detectors and how they operate (flame/chemical, ultrasonic, electronic sniffers) • How background refrigerant concentration can cause false alarms or constant readings • The need for a sensitivity or range adjustment or "zeroing" feature on some detectors

💭 Think About

• Which of the illustrated devices actually measures refrigerant concentration in the air rather than just listening for sounds or changing flame color? • Looking closely at each device, which one appears to have controls or indicators for different sensitivity levels or ranges? • For a space that already has some refrigerant in the air, which design would realistically need a way to be set to a new baseline so it can still detect small additional leaks?

✅ Before You Answer

• Carefully inspect each illustration for any labeled controls or multi-level indicators that suggest sensitivity or range settings. • Ask whether background refrigerant would affect the detector’s principle of operation (sound vs flame color vs gas concentration). • Eliminate any detectors whose method (e.g., purely acoustic or visual) would not require compensation for ambient refrigerant levels.
