WorkRoom:
- The internal material is 304 stainless steel, mirror surface, rust-proof to high and low temperature and Moisture corrosion, nice ruggedness and long life.
- 2 pieces of adjustable and removable SUS304 stainless steel punching sample shelves, conducive to the air circulation, standard load of 30KGS for each layer of sample shelf.
1pc Temperature sensor PT-100A - 1pc exhaust port. When making the 1kpa pressure, the interior air will exhausting from this port.
Controller:
- PID programmable color touch screen controller
- The set system language is English for standard
- Control and display workroom’s temperature, pressure
- Ethernet interface, for PC link
- USB port, for download the test data
