自動微量傾濁點測試儀

MPC-602/302

New Standard ASTM D6749

No Methanol

新標準ASTM D6749，無甲醛

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系列自動微量傾濁點測試儀，采用微量法測試樣品的傾點，取樣量少，測定過程由計算機自動完成，無需人工干預，測定速度快而結果準確。測定樣品的同時可同時測定樣品的濁點。儀器進行傾點測試時，沒有采用傳統的“傾斜法”，而采用了新的標準ASTM D6749 “空氣加壓法”。測試結果與ISO3016和ASTM D97是所描述的傾斜法完全一致。樣品的測試間隔為1℃/2℃，并同時連續測試2-3次，測試結果具有更好的重復性和再現性。

MPC系列有多種型號可選擇。MPC-302適用于3樣品同時測試，MPC-602用于6樣品同時測試。MPC-102L是液冷型，MPC-102A是風冷型。

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.

傳統的“傾斜法”是按3℃間隔測試樣品的傾點，新的標準按1℃間隔測試樣品，儀器測試精度大于試驗標準測試規定,可以保證試驗結果的精度更高。“氣壓法”也可有效避免降溫過程中，樣品的蠟狀析出和冰晶體對結果的干擾。

EASY SAMPLE HANDLING: 采樣少，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. 樣品僅需求4.5毫升，玻璃小型樣品杯是一個可取放的瓶狀試管，操作極其簡單。

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.

選好樣品后，輸入測試參數，預期的傾/濁點數據，按下“開始”鍵。測定過程由儀器自動完成，無需人工干預。當到檢測出傾點后，樣品被自動加熱至與室溫一致。從而可在短時間內進行多組測試。

相較于傳統測試方式，“氣壓法”的效率更高，一般只要傳統方式的1/3 或 1/2的時間，就可以完成測試。可在短時間內進行多組測試。
