The backlit LCD displays moisture readings, relative humidity, air temperature, dew point, and other relevant data. Icons indicate measurement mode, battery status, and other functions.
4.3 Modes de mesura
The FLIR MR77 offers multiple measurement capabilities:
- Pinless Moisture: For non-invasive moisture detection up to 0.75 inches (19 mm) deep. Place the back of the meter flat against the surface to be measured.
- Pin Moisture: Use the external pin probe for direct contact measurements in materials like wood or drywall. Insert the pins into the material.
- Humitat relativa (RH): Mesura el percentatgetage of moisture in the air using the integrated or external RH sensor.
- Temperatura de l'aire: Measures ambient air temperature.
- Punt de rosada: Calculates the dew point temperature based on RH and air temperature.
- Non-Contact IR Thermometer: Use the IR button and laser pointer to measure surface temperatures.
