NC-860S Natural Convection Chamber - Multi-zone Temperature Control, Accuracy ±0.5 Degrees Celsius

The natural convection temperature chamber simulates actual indoor ambient temperature, offering precise temperature control and excellent temperature uniformity. Unlike forced convection chambers, it simulates natural convection in a windless indoor environment, allowing for the understanding of a product's heat transfer characteristics under real-world use or stringent high-temperature conditions.

Main Purpose: To simulate natural convection, airflow, and temperature control in a real-world environment.

Features:

1. Airflow similar to indoor atmospheric conditions;

2. Repeatable wind field and turbulence intensity;

3. Defineable temperature uniformity;

Applications: Suitable for testing computers, mobile phones, electronic components, PSUs, D2D, networking products, LEDs, etc.

Technical Parameters

1. Temperature Range: Ambient temperature +3℃~70℃, maximum temperature rise 45℃, maximum temperature ≤70℃

2. Internal Chamber Dimensions: W860mm*D860mm*H1160mm

3. External Chamber Dimensions: W920mm*D1250mm*H1550mm

4. Quality Standard: A 9-point temperature measurement report is included with the product. The standard deviation between the measured temperature at each point and the average temperature of the 9 points is <2℃. (Specified test temperature points are 40℃, 50℃, 60℃, and 70℃)

5. Point Average Temperature: After the test chamber temperature reaches equilibrium, samples are continuously taken at each of the 9 specified temperature points for 10 minutes at a frequency of 10 seconds. This average temperature is recorded as the point average temperature for that point.

6. Set Average Temperature:

The average temperature of the 9 point average temperatures is then used as the set average temperature for that set temperature.

Main Structure Introduction
