Specifications Wavelength range 光谱范围 4000 to 600 cm-1 Wavelength accuracy 光谱精度 ±3 cm-1 Photometric range % transmittance, absorbance Scan time扫描时间 3, 6, 12, or 24 minutes Display显示 seven-segment, 4-digit LCD Source lamp Nichrome-wound ceramic core Detector DTGS (deuterated triglycine sulfate) Sample compartments 150-mm square Output输出接口 RS-232, 0 to 1 VDC Dimensions 外形尺寸 26"W x 8"H x 15"D Power 电源 115/230 VAC, 50/60 Hz Most cost effective infrared system available Single beam optical design provides dual beam capabilities Nitrogen purge not required liminate costly gases Connects easily to a computer or recorder Simply stated, this is the easiest IR spectrophotometer to operate and maintain! Advanced self-help menus guide you every step of the way. Analysis requires no expensive nitrogen purge for moisture or CO2 prior to use. Single-button controls set all instrument parameters for operation and rapid data collection. High energy optical design and a sensitive DTGS detector provides excellent resolution over the full infrared range. Maximum performance is achieved with a fast scanning mechanism that is completely microprocessor driven ou get dual-beam capabilities with just a single beam optical bed. Display simultaneously indicates wavelength, transmittance or absorbance, scan type, scan time, and response time in seconds. Easy Scan software (included) easily accommodates the needs of first time, intermediate, or advanced spectroscopists to view and save spectra, to collect and store data, and to send output to a computer. The minimum system requirements are Pentium 166 and Windows 95. Bidirectional RS-232 interface lets you connect an optional recorder for hard copy of results. Optional advanced software packages (sold separately) for Windows ?  provide you with comprehensive instrument control, data manipulation, graphs, and library search capabilities. Order optional software or recorder from Accessories at right.
