Feature: RH range: 20%-60%RH Display: LED digital display, touchable microcomputer panel, temperature and humidity switchable display. Drawers: 8 Power consumption: av 16W Voltage: 110-220V Character: 1) Adopting shape memorial alloy dehumidification methods to control RH to 20-60% at fixed point, keeping dehumidification even if accidentally powered off 24hours. 2) The moisture absorption material inside dehumidification module can purify air polluted by chemistry such as sulfide and alcohols. 3) Environmental protection and energy saving, no counter-humidity, no heating, no condensation dripping, no fan noise. 4) Non-magnetic and non conductivity design: all body is designed by non—magnetic, gas seal with steel ball slide railand bilateral non-magnetic airtight stripe, (non-magnetic airtight stripe can avoid damage of demagnetization), 1.2mm steel for body, non-conductive ABS material for drawer and panel. (steel drawer is conductive and not suitable to place disk.) 5) Suitable for storing disk, CD, microfilm, recording tape etc.
