The HT series Oxidation Baths meets the requirements of ASTM D943, D2893*, D4310, D6158, AOCS12-57* test methods (* modified version for these methods is available).
Each test position’s sleeve is individually heated and controlled with temperature stability of ±0.1º C. A digital display controller is dedicated for each position and is independent of the others. The set point between any neighboring tube may differ by as much as ±40º C, thus allowing tests at varying temperatures in the same apparatus. Each position’s temperature may be independently adjusted in 0.1º C increments. Temperature control parameters may be individually adjusted for optimizing the temperature stability of each position. The operating temperature range is from +50º C up to +300º C.
Each test position has one float-in-tube flowmeter positioned in front. The oxygen flow rate is maintained at 3 ± 0.1 L/hr with a micro precision valve. An oxygen pressure regulator is provided.
Temperature control is provided by a digital display PID controller providing stability of ± 0.2º C or better. In the event of primary controller failure each heated tube is individually protected against temperature runaway. Useful temperature range is from +40 to 240'C.
Water flow to each condenser is controlled by a valve mounted on the back panel. This is available only if the condenser water flows directly to a waste drain. If a recirculating chiller is to be used, only one flow valve is provided for each group of 12 condensers which must be arranged in series.
As an option, each position may have either a glass tube flowmeter or a mass flow controller precisely inputting the air or oxygen into the test specimen. The individual mass flow controllers are adjustable via the remote PC or the Integral Touch Screen interface. A supervisory control and data acquisition,(SCADA), package is also available from either a remote PC or an Integral Touch Screen interface.
