自动微量法残炭测试仪
ACR-M3

ACR-M3 is a tester to be used for the determination of the amount of carbon residue formed after evaporation and pyrolysis of petroleum material under certain conditions and is intended to provide some indication of the relative coke forming tendency of such materials.
ACR-M3自动微量法残炭测试仪是测试石油产品残炭含量的专用仪器。残炭是石油产品或原料经过高温分解后的残留物质，而残炭含量是判定石油产品或原料的组份的重要指标之一。

Note-About Micro Carbon Residue Test: A weighed quantity of sample is placed in a glass vial and heated to 500℃ under an inert (nitrogen) atmosphere in a controlled manner for a specific time. The sample undergoes coking reactions and volatiles formed are swept away by reported as a percent of the original sample as “carbon residue (micro).”
Micro Method offers advantages of better control of test conditions, smaller samples, and less operator attention compared to Conradson
Carbon Residue test to which it is equivalent.
Up to twelve samples may be run simultaneously including a control sample.
微量残炭法是经典型康氏残炭法的更新换代方法。称重样品在惰性气流保护下的高温加热到500℃，并保持一定的时间，再称量出试验过程后的残留的组份，与原样品重量的比值就是样品的残炭量。相比较于康氏残炭法，微量法试验的试验条件，试验环境更容易掌控，试验结果的重复性和再现性非常好，样品用量也小。相关的试验规程上已经确定了微量残炭法测定结果与常规的Conrachson（康氏残炭法）的残炭测定结果相一致。按规定，微量法试验zei多可一次测试12个样品。

SMALL SAMPLE: Test can be run with a small quantity of sample (0.15 to 1.5g for small vials, 3.0g for medium vials and 5.0g for large vials, depending on carbon residue content).
试验样品需求量很少：仪器每次能测定6～12个样品（大样品管6个，或小/中样品管12个），加热过程自动控制，同样品测试重复性非常高。（取样量：小样品管0.15 - 1.5g ；中样品管3.0g ；大样品管5.0g）




EASY OPERATION: Test automatically proceeds exactly as prescribed by simply pushing the START switch. Pressure controller (2nd stage regulator) and solenoid valve supply constant pressure. No fine tuning is required after test starts. The buzzer sounds intermittently for 10 seconds when the process is finished. 操作简单：仪器操作十分简单，操作时仅需按动“启动”键,一切均由仪器严格按照标准程序自动进行测试, 无需任何人员操作和判断。试验过程结束后,仪器自动电子音讯10秒以提示用户处理。

EQUIPPED WITH GAS FLOW METER: With the N2Gas flow meter and needle valve fitted on the front panel, process parameters can be easily checked and calibrated. 仪器本体前方自带浮子流量计，流量控制显示清楚直观，也可用于日常维护中的计量校验。

VINYL LAMINATED TRAP: The condensate trap is equipped on the front of the tester. Thanks to this, the condensate volume is easy to confirm and the trap easily attaches and detaches. Trap jar is vinyl laminated for the safety. 废气由加热炉下方专用的耐温防爆冷凝瓶收集，拆卸简单后，容易清洗。

EXCELLENT REPEATABILITY/REPRODUCIBILITY: Repeatability and reproducibility are excellent. Since the electronic temperature control is far more precise compared to that of Conradson method’s. 微量法试验的重复性和再现性非常好，其测定结果与常规的Conrachson（康氏法）残炭测定结果相一致。
