An airless heat sink oven maintains a constant temperature of columns, valves and TCD for reliable and accurate results. Durable Valves. At 14’’X12’’X8’’ (36X31X20 cm) and 35 lbs (15.9 kgs) for Class 1 Div 2 the chromatograph is small. This tiny footprint makes it easy to wall mount or fit into analyser shelters. Also, installation is simple because the controller and analyser are in one unit versus traditional two unit transmitter-analyser unit design. Excellent sensitivity across a full range. Certified for accuracy of measurement by various regulatory authorities. Rapid 3-4 minute response...
