AF650（ASTM色标）石油比色仪
将1个内径33mm的圆柱形玻璃瓶内加入半瓶样品。为消除玻璃池壁对测量颜色的影响，将另外两个同样是33mm圆柱形玻璃瓶充满蒸馏水与样品瓶一同置于仪器内，样品池位于中间。棱镜将样品和两个标准板的颜色同时折射到统一的视场中。不清澈透明的样品，如石蜡，先加热到溶点以上再测量。色度单位大于8.0的深色样品可用煤油溶剂稀释后测量。
通过目视方法可检测润滑油、民用燃油、柴油、矿物绝缘油和固体石蜡等石油产品的色度
符合ASTMD1500，ISO2049，IP196，DIN51578，BS5859，JISK2580，NFT60-104，NBNT52-109，FTM719102等标准。
ASTM色度标准
比色盘-1：0.5,1.5,2.5,3.5,4.5,5.5,6.5,7.5
比色盘-2：1.0,2.0,3.0,4.0,5.0,6.0,7.0,8.0
ASTMD1500定义的ASTM色标是检测石油色度的*常用的一个标准。按照ASTM色度，将16块标定了光投射率和色度的玻璃滤光片镶嵌在两张色度盘中，以0.5个色度单位为间隔从0.5（*浅）递增到8.0（*深）。
主要型号：

The MTM Series of torque transducer are designed to provide an economical way to measure and calibrate multiple torque tools. The MTMDP models (MTMDP-2S pictured) include an integrated display for a fully integrated tester. Historically, transducers had to be purchased individually and connected to a display via a switch box or a group of cables. With the MTM series, up to 4 transducers can integrated in one compact housing. The small footprint also allows for a clean, well-organized work space. This helps eliminate the endless searching for cables, adapters, and other accessories that may be needed. Features such as independent CW and CCW calibration, multi-point linearization, metrology grade transducer shafts, and overload protection to 200% of full scale are standard. All of the above translate to a better product for you at an unbeatable price. * MTMDP-2 coupled with an MTM-4. Features
Available with 2, 3 or 4 torque transducers Selectable units of: Ft-lb, IN-lb, IN-oz, KGF-m, KGF-cm, GF-cm, CN-m, N-m Small footprint of the MTM allows for a clean, well-organized work space 200% Overload protection
LED Indicator Shows Active Transducer External transducers can be connected with cable input Includes NIST Traceable calibration certificate with data for each transducer Replaceable shaft design. If one shaft is damaged, replace that shaft, not the entire unit.
