| System Main Composition |
| Chamber Body | The inner chamber is made of SUS304# stainless steel plate, rounded
shape, smooth, easy for clean |
| The inner chamber is made of 304# brushed stainless steel plate,
rounded shape, smooth, easy for clean |
| Lead hole: the inner and outer chamber are equipped with a
threading hole with a rubber stopper |
| Insulation material: polyurethane foam |
| Observation window: double-layer explosion-proof tempered glass
door |
| Shelves: Made of 304 stainless steel, detachable shelves |
| Heating System | Heating method: electric heating |
| High quality nickel-chromium wire electric heater, contactless
control (SSR) |
| Humidification System | Humidification method: external humidification structure |
| Cooling System | German Bock semi-tight compressor or German BITZER semi-compact
compressor |
| Non-fluorine environmentally friendly refrigerant R404A R23, in
line with environmental regulations, safe and non-toxic |
| Shell and tube condenser (water cooled) |
| High-performance fin type automatic load capacity adjustment,
long-term use of low temperature and high humidity conditions
without frosting. |
| Control System | Touch screen: Weinview programmable temperature and humidity
controller (7 inch 16-bit true color touch screen) |
| Temperature control: PID self-tuning, using Class A PT100 platinum
resistance sensor |
Function: fixed value test and program test Fixed value test: When the test environment requires only a single
temperature and humidity, selecting this mode to set the required
temperature, humidity and running time. Program test: When the test environment requires multiple
temperatures and humidity, select this mode to set the temperature,
humidity and running time of each program. User can set the program
running sequence. The program group is up to 100 groups. |
| Data Storage | With temperature and humidity curve interface, with standard R232
interface or U disk communication interface, the data can be
downloaded, and the data changes and processes can be recorded. |
| Safety Protection | Power-off memory function, phase sequence protection, leakage
protection, over-temperature protection, compressor overload
protection, water shortage alarm, abnormal protection |
| Safety Protection Device | Heater air-burning protection switch, heater over current circuit
breaker, circulating fan over current overload protection |
| Compressor high voltage protection switch, compressor overheat
protection switch, compressor over current protection switch |
| Under-reverse phase circuit breaker, no-fuse switch, zero-crossing
gate fluid power controller |
| Alarm Indication | When the above protection occurs, the equipment stops running, an
audible and visual alarm is issued, and the fault location is
displayed on the meter. |
