NATO Supply Class 6685 is a classification within NATO Supply Group 66, which is dedicated to Instruments And Laboratory Equipment. Specifically, Class 6685 focuses on Pressure, Temperature, And Humidity Measuring And Controlling Instruments.

This class includes a wide range of instruments used to measure and control pressure, temperature, and humidity in various applications. Some examples of instruments in this class include:

1. Pressure Gauges: These instruments are used to measure the pressure of gases or liquids in a system. They typically consist of a dial or digital display that shows the pressure reading.

2. Thermometers: Thermometers are used to measure temperature. They can be digital or analog and may be designed for specific temperature ranges or applications.

3. Humidity Meters: These instruments are used to measure the amount of moisture or humidity in the air. They are commonly used in weather monitoring, HVAC systems, and industrial processes.

4. Pressure Transmitters: These instruments are used to measure and transmit pressure readings electronically. They are often used in industrial applications where remote monitoring or control is required.

5. Temperature Controllers: These instruments are used to regulate temperature in systems or processes. They typically include a sensor to measure the temperature and a control mechanism to adjust it as needed.

6. Humidity Controllers: Similar to temperature controllers, humidity controllers are used to regulate humidity levels in systems or processes. They can be used in applications such as climate control systems or manufacturing processes.

These are just a few examples of the instruments included in NATO Supply Class 6685. The class encompasses a wide range of measuring and controlling instruments related to pressure, temperature, and humidity.
