Chromatograph (GC1690J )

Product Description

Innovation
1.  Five steps temperature control program, setting rate from 0.1~40º/min, can be setted arbitrary, time setting range: 9999.9min.
2.  Three detectors(TCD+FID) can be setted on the instrument simultaneously. Detector's gas flow controllers use combination valves, to get realiblity.
3.  Bright LCD display, can display all of the patements, e. G. Temperature, pressure and gas flow.
4.  Use new type control technique, It is one of the top grade standard chromatograph.
