The main product features:
This high-low temperature chamber serves as a vital testing
apparatus, replicating operational scenarios of products under
extreme thermal conditions. It meticulously regulates the interior
temperature, subjecting products to both cyclic and sustained tests
across a broad temperature range, thereby assessing their
resilience to weather, stability, and material compatibility.
- Air supply characteristics: air supply from the upper part and
return air from the lower part to ensure stable uniformity.
- Refrigeration mode: Air-cooled mode is adopted to automatically
switch the flow rate of the refrigeration system according to
different working conditions, and the constant section cuts off
redundant systems to maintain energy-saving operation and cooling
control.
- The combination of multi-stage evaporators can obtain more uniform
and efficient cooling exchange efficiency and cooling output.
- Heating tube: bare wire nickel-chromium alloy electric heating
tube.
- Humidification system: All stainless steel embedded humidification
tubes are used, the insulation resistance is greater than 50MΩ, and
it has an anti-dry explosion-proof protector.
- Test hole: A standard test hole, located at the left side of the
work room which is convenient for users to connect external power
supply.
- Window: The door frame is equipped with electric heating function,
which can prevent frosting and condensation, and is convenient for
users to observe and test.
- Insulation layer: rigid polyurethane foam + ultra-fine
environmentally friendly glass fiber cotton to ensure temperature
stability.
- Control method: 7-inch touch screen (resolution 800*480) setting,
easy to operate and supports switching between Chinese and English.
- Software function: It can store temperature and humidity data and
export it in XLS form.
- Protection functions: overheat protection, overpressure protection,
overtemperature protection, leakage protection, short circuit
protection, water shortage alarm.
Application:
The high and low temperature test chamber is widely used in
industries such as electronics, automotive, and aerospace to
simulate the working environment of products under extreme
temperatures, evaluating their weather resistance, stability, and
material adaptability, thereby ensuring product quality and
reliability.
