便攜式折射儀
。只需將***滴樣品直接到棱鏡或把傳感器的樣品。溫度補償系數(shù)可多達十個不同的樣本。單位可以存儲多達1100個測量結(jié)果可以通過紅外接口傳輸?shù)?**個外部打印機或計算機（PC軟件）。背光液晶在°C或°F.校準顯示溫度的選擇是自動的和基于去離子水。測量單位包括折射率（ND），hfcs42，hfcs55，990，°KMW（é，°oechsle（D，CH），W / W %和/ v%的異丙醇，Compact ａnd easy to use, Refracto refractometers are ideal for measurements in laboratory or production environments. They may be used as either benchtop or hand-held refractometers. Simply place a ｄrop of sample directly onto the prism or immerse the sensor in the sample. Temperature compensation coefficient is programmable for up to ten different samples. Units can store up to 1,100 measurement results that can be transmitted to an external printer or computer via infrared interface （PC software included）. Backlit LCD displays temperature selection in °C or °F. Calibration is automatic ａnd based on deionized water. Units of measurement include refractive index （nD）, nD temperature compensated, % Brix, HFCS42, HFCS55, T.A. 1990, °KMW （Babo）, °Baumé, °Oechsle （D, CH）, w/w% ａnd v/v% for isopropanol, ａnd user-defined units.
The Refracto 30PX has an optical glass prism held by a stainless steel ring. The Refracto 30GS has a sapphire prism held by a ring of hard gold-plated brass. Sapphire has a higher refractive index ａnd better thermal conductivity than glass. For this reason, the Refracto 30GS has an extended measuring range ａnd registers sample temperature more quickly.
該行業(yè)開始已經(jīng)由***個不銹鋼環(huán)舉行的***個光學玻璃棱鏡。該行業(yè)30gs已由環(huán)硬鍍金黃銅舉行藍寶石棱鏡。藍寶石具有較高的折射率和更好的導熱性比玻璃。為此，該行業(yè)30gs有***個擴展的測量范圍和寄存器樣品溫度更迅速。Ordering Information: Refracto refractometers are delivered in the PortableLab™, a case complete with two pipets for sample handling, two flasks for samples ａnd cleaning solutions, five cleaning tissues, operating instructions, a CD-ROM with data transmission software, a tutorial, ａnd two 1.5V AAA batteries.
