自动微量倾浊点测试仪

MPC-602/302

New Standard ASTM D6749

No Methanol

新标准ASTM D6749，无甲醛

Model MPC-602/302 has been designed for automatic determination of Pour Point (PP) and Cloud Point (CP) with small specimen size and shorter test time while securing better test precision than the conventional manual method’s. PP measurement is made by utilizing a new automatic method, namely Air Pressure method, which yields eventually no bias against the conventional test method’s, repeatability of 1 ℃, and reproducibility of 2 ℃.(*) This epoch-making accuracy has made PP determination at 1 ℃ intervals make more sense.  The CP/PP mode executes a CP determination and then a PP determination consecutively, which further improves the test throughput. MPC-602 is a 6 tests version, and MPC-302 is a 3 tests version of its original single test model (MPC-102L). ASTM has approved the PP test method: ASTM D6749 on “Standard Test Method for Pour Point of Petroleum Products (Automatic Air Pressure Method)”. *Accuracy information is for typical samples.

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-302适用于3样品同时测试，MPC-602用于6样品同时测试。MPC-102L是液冷型，MPC-102A是风冷型。

POUR POINT AT 1 ℃ INTERVALS FOR HIGHER YIELD IN PROCESS:

The conventional PP test methods yield a rough PP numbers of multiple of 3 ℃, and thus higher resolution in PP determination has been long awaited for more elaborate process control. With the patented Air Pressure method, PP can be now determined at 1 ℃ intervals with high accuracy, since the disturbance on the formation of wax crystal structure through the test process is at a minimal level. When PP is measured at 1 ℃ intervals, typical repeatability and reproducibility are 1 ℃ and 2 ℃, respectively.

传统的“倾斜法”是按3℃间隔测试样品的倾点，新的标准按1℃间隔测试样品，仪器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。“气压法”也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。

EASY SAMPLE HANDLING: 采样少，易操作

Since the required specimen volume is a mere 4.5 ml and the specimen 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。

EASY, QUICK, AND PRECISE PP/CP DETERMINATION:

Just set up the specimen, set test parameters, and then press the START key to start a test. Specimen is cooled at the steepest possible rate without affecting the formation/growth of wax crystal, which has been known to be critical in PP/CP determination. For fuel oils, the specimen may be even pre-heated automatically and then cooled for CP/PP determination, which further improves test throughput.

选好样品后，输入测试参数，预期的倾/浊点数据，按下“开始”键。测定过程由仪器自动完成，无需人工干预。当到检测出倾点后，样品被自动加热至与室温一致。从而可在短时间内进行多组测试。

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。
