Features: Automatic water replenishment function when the water level is insufficient; precision glass nozzle (PYREX), 4000 hours to ensure no crystal blockage; the control instruments are on the same board, simple operation, clear at a glance; with double over-temperature protection, insufficient water level warning to ensure Safe to use; temperature controller adopts digital display, SSR control, and the accuracy is 0.1 ℃; the test tank adopts direct steam heating method, the heating speed is fast and stable, and the standby time is reduced; the spray tower is provided with a cone-type diffuser, which has fog guidance and adjustment The functions of spray volume and uniform spray volume; related materials such as control instruments and nozzles are all European and American brands. Material: Test room: PVC (Germany) gray impact-resistant and corrosion-resistant plate, thickness 5mm, large-scale machines use 8mm thick plate. The upper cover of the test room: a transparent acrylic (Germany) plate with a thickness of 5 mm. The large-scale machines use a high-temperature resistant PVC plate with a thickness of 10 mm, a set of glass windows, a lighting lamp (optional) inside the test room, and an automatic lifting device for the gas arm One group. Refilling tank for drug test: Hidden water level gauge with PVC (Germany) grey impact resistant plate, thickness 5mm, integrated with the machine. Laboratory basket rack: PVC impact-resistant plate can be used to adjust the angle of 15 ° and 30 ° freely (oversized support racks can bear heavier items, which can be made according to customer needs). Saturated air barrel: made of SUS304 # stainless steel, with a thickness of 2mm, and equipped with an automatic water addition controller for automatic water addition adjustment, eliminating manual water addition. Extended base: made of SUS304 # stainless steel plate, thickness 2mm. The display system of the salt spray test chamber: the temperature control of the laboratory is 0-99.9 ℃, the accuracy is 0.1 ℃ (double digit display) (RKC); the temperature control of the saturated air barrel is 0-99.9 ℃, the accuracy is 0.1 ℃ (double digit display) ( RKC); safe temperature control of the liquid expansion of the heating tank tends to 0 ~ 110 ℃ 2 (made in Western Europe); time controller AH5R, precise control of the test process. Control system of salt spray test chamber: Primary pressure regulating valve: 1 set with pressure gauge (first pressure regulation 2 ～ 2.5kg / sqcm); secondary pressure regulating valve: 1/4 ″ PT made in Taiwan, pressure 0-4kg / sqcm Adjustable (spray pressure is adjusted to 1kg / sqcm); pressure gauge 0 ～ 2kg / sqcm, accuracy 0.1kg / sqcm; French imported light buckle switch, which can be buckled more than 10,000 times continuously; Taiwan Shihlin motor electromagnetic contactor (solid state relay ); STON LY2N protection relay; STON MY2N protection relay; YCTV2A702-03 solenoid valve. The spray method of the salt spray test box: continuous salt spray test machine; cone-shaped disperser, with the function of fog guide, adjusting the spray volume, and uniform spray volume; high-precision glass nozzle PYREX 4000 hours to ensure no crystal blockage; spray Volume 1-2ml / 80sqcm / 1h (1 ~ 3ml / 80sqcm / 1h adjustable); collector, horizontal area 80sqcm. Safety device of salt spray test box: low water level automatic warning, automatic state warning, automatic over-temperature protection warning, and air pressure source interruption warning. http: // A4 File Folder,Portable A4 File Folder,Large Capacity A4 File Folder,Plastic A4 File Folder TAISHAN JINRI STATIONERY PLASTIC CO.,LTD , https://www.jinri-folder.com
