The TH-736-D serves as the central control unit for constant temperature and humidity test chambers, orchestrating the complex interplay of heating, cooling, and humidity regulation. It is a fully programmable, high-precision instrument designed to execute demanding environmental simulation profiles with minimal deviation, ensuring adherence to rigorous testing standards.

Technology & Performance

• Intelligent PID Control: Equipped with an advanced PID algorithm featuring auto-tuning, the TH-736-D learns the thermal characteristics of the connected chamber to minimize overshoot and precisely settle at the target setpoint, delivering a typical temperature accuracy of ±0.2 °C and humidity accuracy of ±2% RH.
• Wide Dynamic Range: Capable of controlling environments from a low of -40 °C up to 150 °C, meeting the demands of both deep freeze and high-temperature endurance tests.

Integration & Programmability

• Digital Communication: The built-in RS-485 interface, operating via the standard Modbus RTU protocol, enables seamless integration into automated test systems, allowing for remote monitoring, data logging, and setpoint adjustments from a PLC or PC.
• Multi-Segment Programming: Users can create complex ramp, soak, and cycle profiles directly on the clear LCD interface. This eliminates the need for manual oversight during long-duration tests.

Hardware & Control Outputs

• Comprehensive Actuator Control: It directly manages four independent outputs for heating, cooling, humidification, and dehumidification, solidifying its role as a complete environmental control solution.
