自动微量倾浊点测试仪

MPC-102

New Standard ASTM D6749

No Methanol

新标准ASTM D6749，无甲醛

MPC-102 series has been designed for automatic determination of Pour Point (PP) and Cloud Point (CP) with small specimen size and shorter test cycle time while securing better test precision than the conventional manual methods’. PP measurement is made utilizing a new ASTM test method, namely “Air Pressure Method”(*1), which yields eventually no bias against the conventional test method, repeatability/reproducibility of 1℃/2℃ and 2-3 times faster determinations. The epoc-making high accuracy justifies PP determination at 1℃ intervals, which can help increasing the yields in the process. The CP/PP mode executes a CP determination and then PP determination consecutively, which further improves the test throughput in the lab. In addition to liquid-cooled model MPC-102L, air-cooled model MPC-102A is available. Multiple-tests versions with 6 test heads and 3 test heads are also available for higher volume tests.

MPC-102系列自动微量倾浊点测试仪，采用微量法测试样品的倾点，取样量少，测定过程由计算机自动完成，无需人工干预，测定速度快而结果准确。测定样品的同时可同时测定样品的浊点。仪器进行倾点测试时，没有采用传统的“倾斜法”，而采用了新的标准ASTM D6749 “空气加压法”。测试结果与ISO3016和ASTM D97是所描述的倾斜法完全一致。样品的测试间隔为1℃/2℃，并同时连续测试2-3次，测试结果具有更好的重复性和再现性。

MPC系列有多种型号可选择。MPC-102L是液冷型，MPC-102A是风冷型。MPC-302适用于3样品同时测试，MPC-602用于6样品同时测试。

HIGH PRECISION POUR POINT DETERMINATION: 高精度的倾点测定

The typical repeatability and reproducibility are 1℃ and 2℃ respectively, when PP is determined at 1℃ intervals.(*2) This high precision attributes to the patented Air Pressure method, in which the disturbance to the formation of wax crystal structure through the test process is kept at a minimal and consistent level. “气压法”可有效避免降温过程中，样品的蜡状析出和冰晶体对结果的干扰，按1℃间隔测试样品，精度更高。

*2:Precision information is for general samples such as diesel fuels, base oils and finished lube oils. 柴油，基础油和调和润滑油。

POUR POINT AT 1℃ TESTING INTERVALS:

With this high precision, PP can be determined at 1℃ intervals for more precise process control, and therefore a considerable savings in the procss can be realized.仪器可按1℃间隔测试样品，测试精度大于试验标准测试规定,可以保证试验结果的精度更高。（重复性：倾点±1℃ 或3℃（仪器可按传统方式3℃间隔测试）；浊点：±1℃）

EASY AND QUICK PP/CP DETERMINATION:

Just set up a sample, select a test mode and then press the START key. The sample is cooled at the steepest possible rate without affecting the formation/growth of wax crystal, which has been known to be a critical factor for PP/CP determination. The test cycle time is typically 1/3 to 1/2 of that of the conventional tilting method’s.(*3) 选好样品后，输入测试参数，预期的倾/浊点数据，按下“开始”键。仪器即可按标准自动进行测试，并输出结果。

相较于传统测试方式，“气压法”的效率更高，一般只要传统方式的1/3 或 1/2的时间，就可以完成测试。可在短时间内进行多组测试。

*3:When a diesel fuel oil with PP of –32.5℃ is tested, the Air Pressure method took 45 minutes while the conventional tilting method took 140 minutes. Note that the Japan Industrial Standard defines PP in 2.5℃ increments 柴油的倾点一般在–32.5℃左右，按传统方法测试，每隔2.5℃测试一次，一个测试过程需要140分钟，而应用“气压法”的测试过程只要45分钟，效率更高。

EASY SAMPLE HANDLING: 采样少，易操作

Since the required sample volume is a mere 4.5mL and the sample cup is a test-tube type removable jar, the sample handling is extremely easy.样品仅需求4.5毫升，玻璃小型样品杯是一个可取放的瓶状试管，操作极其简单。

COMPACT DESIGN &ENERGY EFFICIENT:

Use of Peltier Cells for sample cooling/heating made this “mini” tester not only compact in design but energy efficient. Depending on the temperature range, either air, tap water or small chiller with anti-freeze suffices the cooling requirement. No methanol is required. 仪器整体为台式结构，体积小，占地少，仪器本体内置半导体制冷源及加热装置。使用小型样品杯，取样量少，制冷迅速，效率很高。配合不同的冷浴介质，用于不同的测量范围。无需甲醛。
