150L Programmable Constant Temperature and Humidity Test Chamber

Programmable Constant Temperature and Humidity Test Chamber

Product Overview

Simulated industrial parts, major accessories and semi-finished products, such as electronic components, auto parts, laptop computers, etc. Under combined climatic, environmental, temperature and humidity conditions (high and low temperature operation, storage, temperature cycling, high temperature and high humidity, low temperature and low humidity, condensation tests, etc.), test whether the adaptability and inherent characteristics of products change, as well as their reliability, and conduct temperature and humidity environmental tests.
Comply with the requirements of international standards (IEC, JIS, GB, MIL, etc.) to realize consistent international measurement procedures (including test procedures, conditions and methods), eliminate cognitive discrepancies and reduce the scope of measurement uncertainty.
Exquisite structural design: featuring curved shapes and matte line finishing for a high-grade appearance. Equipped with flat non-rebound handles, it is easy to operate, safe and stable.

150L Programmable Constant Temperature and Humidity Test Chamber

Working principle:

The constant temperature and humidity balancing control system adopts PID mode to control SSR, enabling the heating and humidification capacity of the system to match the heat and moisture loss capacity.
The temperature measurement signals from dry and wet bulbs are transmitted to the controller CPU after A/D conversion for comparison with RAM data, and then output to the I/O board. The I/O board issues instructions to operate the air supply system and refrigeration system. Meanwhile, PID controls the SSR to activate heating SSR or humidifying SSR, so that heat and moisture are evenly distributed into the test chamber via the air supply system to realize balanced temperature and humidity regulation.

Air Supply Circulation System:

Adopts multi-blade centrifugal wind wheel and sealed motor, which is less prone to oil leakage and core displacement.
Features diffused vertical and horizontal air exchange as well as arc-shaped circulating air supply mode.
Equipped with adjustable side air outlets and protective mesh return air inlets.
Special adjustable louver air supply circulation system.

Refrigeration System:

Compressor: Original fully hermetic compressor
Refrigerant: Adopts new eco-friendly green refrigerant R404A (DuPont, USA) with zero ozone depletion potential
Condenser: Wave fin type forced air-cooled condenser
Evaporator (Dehumidifier): Inclined FIN-TUBE evaporator
