自動熒光定硫儀

能量色散X射線硫含量儀

RX-620SA

RX-620SA determines total sulfur in petroleum products, such as gas oil, fuel oil, crude oil and naphtha, using energy dispersive X-ray fluorescence(EDXRF) method, which is an accurate, non-destructive, economical and yet quick method prescribed in ISO 8754 and ASTM D4294-03. Once a sample is set, the total sulfur is determined automatically in 300 seconds(typical). The model RX-620SA is a 12-sample carousel model. After its successful predecessors, this fourth generation has been developed to further improve the accuracy and ease of use.

RX-620SA 是按“能量色散X射線熒光光譜法（EDXRF） ”測定石油產品硫含量的儀器。可通用于車用汽油，柴油，原油，石腦油，渣油，潤滑油基礎油，液壓油，噴氣燃料和其他餾分油在內的碳氫化合物中的硫含量測定。適用于ISO 8754 ，ASTM D4294-03.，GB/T 17040的標準。測試過程簡單高效，試驗結果準確和重復性良好，是一種經濟的無損測試方法。通常情況下，測試一組樣品多要300秒，RX-620SA帶有一個自動旋轉的測試盤，可連續測試12個樣品。作為“田中科學”的第四代產品，儀器性能有了進一步的提升，使用更簡單靈活。

HIGH PRECISION: Pulse height analysis(PHA) is automatically carried out before each measurement to adjust the system. This innovative system design has further improved the precision.

精度高：高精度脈沖電子計數系統，精確而高效。

WIDE RANGE OF SAMPLES: Patented “Diamond Parameter Method” accurately compensates for measurement error caused by different carbon/hydrogen(C/H) ratio of individual sample. This state-of-art technology enabled measurement of wide range of samples of different C/H ratios with uncompromising precision.

測試范圍廣：獨有的 “Diamond Parameter Method”,無論是輕油,原油,重油。從低濃度到高濃度,均能在短時間內通過簡單的操作,高精度地測出硫分值。對于不同的碳氫化合物（C/H）也能自動補正

AMBIENT TEMPERATURE AND BAROMETRIC PRESSURE COMPENSATION: Compensation for ambient temperature and barometric pressure are made automatically to drastically minimize the drift. 對于環境的影響,可通過氣壓補正,溫度補正進行自動調整。

AUTOMATIC CALIBRATION: Set certified calibration standards and start automatic calibration program to carry out automatic calibration. Either multiple point calibration at up to 12 points or two point calibration starts. 比對標準樣品，儀器可進行自動的2點校正和多點校正。

CAROUSEL TYPE SAMPLE CHANGER WITH ACRYLIC COVER: X-ray shielding is by a metallic cover moving downward on the objective sample cell. Since the acrylic dust cover is not intended for shielding X-ray, it may be opened during a test, allowing access to sample cells in the cue.

自動旋轉樣品臺：樣品測試區（X射線區）有獨立的金屬護罩獨立分隔，通過旋轉平臺一一更換，每一個樣品都是獨立測試的。即使在測試過程中也可以打開儀器外罩，更換或添加樣品，不會有X射線泄露的危險，尤其適用于大量集中連續的樣品測試。
