Step in constant temperature and humidity test chamber, step in constant temperature and humidity test chamber, constant temperature and humidity test
Product details

Product Features:
System capacity: Can log in to 150 programs x 1500 segments, with the number of segments freely divisible and programs freely interconnected.
Loop setting: It can execute 9999 × 999 loops and can also cut out 5 independent partial loops.
Control method: Adopting intelligent PID+SSR/SCR bidirectional synchronous output, including advanced slope control logic.

Data setting: Touch based dialog box setting mode, easy and clear operation, built-in directory data management system.
Curve drawing: When the temperature, humidity, and time data are set, they can be immediately converted into the set curve, and the actual operating curve can also be obtained during operation.
Time signal: 3 sets of timing control output interfaces, paired with 10 different timing control modes, facilitate the execution of timing planning for external drive components start/stop. End temperature: When completing the test, you can choose to return to room temperature to facilitate the removal of the test substance.
Safety check: 15 fully functional system detections to ensure the safe operation of the machine And it can automatically display the fault time, project, and troubleshooting measures.
Abnormal tracing: It can display historical data of recorded faults, such as statistical records of the causes and times of past faults.
External protection: an electronic over temperature protection device independent of the main controller, which can set a temperature upper limit protection for the tested object.
Communication Interface: Equipped with standard communication interface devices for RS-232 and RS-485, it can be simultaneously connected to a personal computer (PC) for multi machine control and management.
CF device: A 256MB ultra strong memory capacity CF device can be selected to replace traditional expensive paper recorders; It has the function of self diagnosis, and the recording interval can be freely selected.
Scalable:
CF data reading device
