Moist Cabinet for curing mortar and concrete test specimens has 11ft³ capacity and heated, triplepane glass door to minimize condensation for observation of specimens. Remote alarms and RS-232 interface for temperature and humidity allow continuous monitoring and data acquisition with user’s PC. An optional factory-installed 7-day chart recorder is available. Temperature range is from 32°—140°F (0°—60°C), settable in 0.2°F (0.1°C) increments. Humidity controls are settable in 1.0% increments and maintain up to 95% humidity.
Positive horizontal airflow insures temperature uniformity to ±0.6°F at 77°—98.6°F (±0.3°C at 25°—37°C). Chamber temperature and humidity are shown on LED displays. Audible and visible alarms indicate temperature and humidity variations beyond setpoints.
Three stainless steel shelves with 50lb (23kg) stationary capacity, adjustable on 2in (50mm) centers are included. Up to eleven shelves are accommodated in the 31 x 27 x 24 in (78.7x68.6x60.9cm) 20-gauge stainless steel chamber. Extra standard shelves or perforated stainless steel shelves are available. Exterior case is 18-gauge powder-coated steel, 38x32x51.5in (96.5x81.9x130.8cm), WxDxH. Total weight of unit is 575lb (261kg).
Heat is provided by two 600 Watt wire-wound elements. Cooling is via a 1/4hp, non-CFC compressor. A steam generator provides chamber humidity. User-supplied water source must be rated between 50K-ohm and 1meg-ohm resistance. Electrical requirements: 208-220V/60Hz, 3 wire, single phase, 14 amp. or 220-240V/50Hz, 2 wire, single phase, 13 amp.
