自動微量傾濁點測試儀

MPC-102

New Standard ASTM D6749

No Methanol

新標準ASTM D6749，無甲醛

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-102L是液冷型，MPC-102A是風冷型。MPC-302適用于3樣品同時測試，MPC-602用于6樣品同時測試。

HIGH PRECISION POUR POINT DETERMINATION: 高精度的傾點測定

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. “氣壓法”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，按1℃間隔測試樣品，精度更高。

*2:Precision information is for general samples such as diesel fuels, base oils and finished lube oils. 柴油，基礎油和調和潤滑油。

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.儀器可按1℃間隔測試樣品，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。（重復性：傾點±1℃ 或3℃（儀器可按傳統方式3℃間隔測試）；濁點：±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) 選好樣品后，輸入測試參數，預期的傾/濁點數據，按下“開始”鍵。儀器即可按標準自動進行測試，并輸出結果。

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。

*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 柴油的傾點一般在–32.5℃左右，按傳統方法測試，每隔2.5℃測試一次，一個測試過程需要140分鐘，而應用“氣壓法”的測試過程只要45分鐘，效率更高。

EASY SAMPLE HANDLING: 采樣少，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.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。

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. 儀器整體為臺式結構，體積小，占地少，儀器本體內置半導體制冷源及加熱裝置。使用小型樣品杯，取樣量少，制冷迅速，效率很高。配合不同的冷浴介質，用于不同的測量范圍。無需甲醛。
