1. Introducció
The Mastfuyi FY867 is a multifunctional, battery-powered instrument designed for precise environmental monitoring. It features a user-friendly interface, convenient button operation, and an intuitive 2.4-inch full-color HD display. This device accurately measures four critical environmental parameters:
- Temperatura ambient: La temperatura actual de l'aire.
- Relative Humidity (%RH): The amount of moisture in the air relative to the maximum it can hold.
- Dew Point Temperature (DP): The temperature at which air becomes saturated with water vapor, leading to condensation. Crucial for preventing mold, rust, and damage in HVAC and storage.
- Wet Bulb Temperature (WB): The lowest temperature achievable by evaporating water into the air. Key for assessing heat stress and cooling system efficiency.
This instruction manual provides essential safety information, operating procedures, and technical specifications. Please read it carefully before using the product to ensure safe and effective operation.
2. Safety Operation Guidelines
Warning: Before using the product, please carefully read these safety guidelines.
