燃烧法沥青含量测试仪
性能可靠稳定的沥青含量测定燃烧炉
热科学仪器NCAT沥青含量燃烧炉能够容纳大量的测试样品，降低劳动成本。
沥青含量燃烧炉通过环境友好、具有成本效益的燃烧法测定沥青含量，节约了时间和成本。
燃烧法替代昂贵和费时的溶剂萃取法，去除了溶剂的成本，在最少26-32周的溶剂成本的节省就能支付燃烧炉的费用。
本设备是与美国国家沥青技术中心（NCAT）共同开发，制定了燃烧法测定沥青含量的行业标准。本系统是起草和制定ASTM D6307 和 AASHTO T308标准的基础，NCAT专门用本设备进行了12个实验室所提出的现场试验，测试结果和性能证明在NCAT有备案证明。

The most reliable asphalt content ignition furnace with a proven track record.
Thermo Scientific* NCAT asphalt content furnace accommodates larger sample testing, reducing labor and costs.
The Thermo Scientific NCAT Asphalt Content Furnace saves time and money by using an environmentally friendly, cost-effective ignition method to determine asphalt content. Ignition method replaces the costly and time consuming solvent extraction method by eliminating the cost of solvent and can pay for the cost of the furnace in as little as 26-32 weeks based on solvent cost savings alone
The Thermo Scientific NCAT Asphalt Content Furnace, developed in conjunction with the National Center for Asphalt Technology (NCAT), set the industry standard for determining asphalt content by the ignition method. This system was integral to the drafting and passage of ASTM* D6307 and AASHTO T308. A 12-lab roundrobin field test was conducted by NCAT exclusively with this furnace. Results and proven performance are documented by NCAT.
Operating Features
-
Asphalt content of bituminous paving mixtures is accurate to 0.11%
-
Accommodates samples up to 5000g
-
Automatic mode: endpoint is detected and software ends the test, prints the results and beeps until STOP is pressed to unlock door (in accordance with AMRL specifications)
-
Manual mode: endpoint is detected and furnace begins to beep but continues to test until STOP is pressed to unlock door, then and results print
-
Furnace software automatically compensates for weight change due to sample and basket assembly temperature change
-
24-hour/7-day timer can be programmed to preheat furnace
-
RS-232 port provides data interface with a PC for graphical data analysis
