■ Features & Functions
Control method and exhaust mode can be selected according to the test purpose.
Emphasizing the correlation with many test conditions conventionally performed, two control methods (saturation and unsaturation) and three exhaust modes (slow cooling with humidity maintained mode, cooling with moisture kept mode and rapid exhaust mode) are installed in this product. You can select a control mode and exhaust mode from them according to the test purpose.
There are two types of operation modes.
A fixed-value operation mode, and a programmed operation mode that allows registration of total 1500 steps within maximum 150 operation patterns are equipped.

Special concern to the chamber
・Round-shape and dual vessel structure that can exhibit excellent performance.
The PC-R8/R8D series HAST chambers adopt a dual vessel structure in which the test chamber and the steam generator are independent from each other. The dual vessel structure can perform more stable test evaluation compared to the single vessel structure, because it has less mutual temperature influence between a test chamber (dry bulb) and a steam generator (wet bulb) while making the best use of the effective area of the test chamber. Each vessel uses a round shape vessel that has reliability in strength and temperature distribution.
・Stain-resistant chamber
Since the chamber is made of stainless steel (SUS316L) which has been subjected to electrolytic polishing treatment to give smoothness and gloss to the chamber surface, the corrosion resistance is improved, and easy to prevent, remove, and clean up stains. Therefore, influence by chamber contamination can be minimized.

Having both safety and functionality
・Door lock by electric clamp system
An electric clamp system with high safety performance is employed for door locking. The door is easily opened/closed simply by pressing a button. An interlock mechanism and door opened/closed confirmation device are also equipped.
・Slide tray
A sample table (tray) on which samples are placed is a sliding type in which the tray is drawn out of the chamber by pulling the door to the front. Samples can be taken in and out safely and easily without placing a hand in the hot chamber after a test.
・Easy connection to voltage application terminals
The voltage application terminals are arranged on the inner face of the door. Connection work with specimens at a voltage application test can be executed outside of the chamber. (The number of voltage application terminals is 20 as standard.)
PC-304R8 / PC-304R8D: Extendable number of terminals is up to 60 in total. (Up to 40 optional terminals can be added.)
PC-422R8 / PC-422R8D: Extendable number of terminals is up to 100 in total. (Up to 80 optional terminals can be added.)

Communication interface allows centralized monitoring and centralized control.
The RS232C port is equipped as standard. All kinds of work such as setting and confirmation of test conditions from a PC, grasping of test state and trouble state, data processing etc. can be performed collectively using special software (Windows). A network system※ that can centralizedly monitor and control up to 16 HAST chambers from a single PC is possible.

Time signal terminals useful for voltage application test
The 4 channels of time signal terminals that can take out the contact output during operation at the required timing is equipped as standard. Test condition attainment detection and ON/OFF setting for each step are possible. If a problem occurs during voltage application test, it interlocks with safety devices and shuts the connection. (For PC-R8D, it is an option.)

 [ Alarm message screen (Troubleshooting) ] The causes and measures for generated alarms are displayed on the message. You can restore the state by operating according to the message. |
■ Two control methods
 |  |
| [ HUM / Unsaturation control ] The unsaturation control mode prevents dew condensation and can set the humidity at any value between 65%RH and 100%RH. In addition, temperature gradients at temperature rise and fall can be set for both fixed value operation and programmed operation, and humidity control is also possible. This mode meets the test conditions defined in IEC 60068-2-66 and JIS C 60068-2-66. | [ STD / Saturation control ] This is a 100%RH saturation test mode, and humidity is maintained at 100%RH from a start. This mode is also called as a wet saturation test, and dew condensation occurs on the specimens. A test that corresponds to the conventional saturated type pressure cooker can be carried out. |
■ Three exhaust modes
| 1.Slow cooling with humidity maintained mode After completion of a test, the test chamber is cooled down slowly with humidity maintained until the chamber temperature becomes 100℃ and the chamber pressure drops to 0MPa. This mode can protect specimens from pressure stress and drying that are caused by rapid exhaust. The high accurate test that minimizes the influence on the specimens caused by taking them out on the way can be performed. |  |
| 2.Cooling with moisture kept mode After completion of a test, exhaust is not carried out until the chamber pressure reaches 0MPa, and air cooling with a fan minimizes pressure stress and drying. Cooling in a short time compared to the slow cooling with humidity maintained mode is possible. |  |
| 3.Quick exhaust mode Immediately after completion of a test, the exhaust valve is opened to carry out exhaust and hot water drainage in a short time. The time from the end of a test to the removal of specimens is the shortest in all modes. This mode is suitable for specimens that are not affected by pressure stress. Data is compatible with the data of a saturated type pressure cooker. |  |
