便携式折射仪
。只需将***滴样品直接到棱镜或把传感器的样品。温度补偿系数可多达十个不同的样本。单位可以存储多达1100个测量结果可以通过红外接口传输到***个外部打印机或计算机（PC软件）。背光液晶在°C或°F.校准显示温度的选择是自动的和基于去离子水。测量单位包括折射率（ND），hfcs42，hfcs55，990，°KMW（é，°oechsle（D，CH），W / W %和/ v%的异丙醇，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.
该行业开始已经由***个不锈钢环举行的***个光学玻璃棱镜。该行业30gs已由环硬镀金黄铜举行蓝宝石棱镜。蓝宝石具有较高的折射率和更好的导热性比玻璃。为此，该行业30gs有***个扩展的测量范围和寄存器样品温度更迅速。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.
