Summary:
Tester structure:
(1) Meterial: Outer: SUS stainless steel plate plastic spraying
Inner: SUS stainless steel plate
Cover: SUS stainless steel plate plastic spraying
(2) Install 8 UV－A or UV－B UV light tubes on the two sides of the studio.
(3) Heating mode: Bladder type cistern heating, who heats up very fast
(4) Cover: Two-way clamshell type, which will be easily open and close.
(5) the inner water will fill automatically, to prevent damaging the empty heating pipes.
(6) Speciman rack is made of stainless steel or aluminium alloy.
(7) Tester bottom use the high-quality fixable PU moving wheel.
(8) Speciman surface parallells to the uv lamp .
(9) Install a automatic sprayer inside the spray-type equipment
(10) Overtemperature protection inside the tester.
Control system:
(1) Temperature and humidity control instruments use the high precision digital display microcomputer integrated controller imported from Korea.
(2) Accuracy: 0.1℃, DPI (dots per inch): ±0.1℃,
(3) Temperature sensor: PT100 Platinum resistance tester
(4) Control mode: thermal balance temperature and humidity adjusting mode.
(5) Temperature and humidity control use P.I.D ＋S.S.R, the system and channel control coordinatelly.
(6) Protections of overtemperature, low water level, overload, leakage, automatic shutdown, etc.
