The 501 series liquid 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 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 the bath is protected by a secondary high limit controller. Useful temperature range is from 40 to 120'C .
The 30 or 60 positions are arranged in two back to back rows (15 or 30 positions each) suitable for those laboratories with an isle bench.
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.

PC-30
|
Windows based software records the maximum and minimum temperature of each test position, oxygen supply pressure, and the total oxygen flow rate for 3 banks of flow meters, with each bank with 10 flow meters. An alarm is triggered alerting the operator when any of the three parameters decrease or increase above a preset limit. The needed electronics to monitor these parameters are included (electronic mass flow meter, RTD probe, pressure sensor). The PC is not included.
|
|
PC-60
|
Same as option PC-30, above, but monitoring total oxygen flow rate for 5 banks of flow meters, with each back with 12 flow meters. |
|
MF
|
Oxygen mass flow controller for each test position provided precise 3 liters per hour of oxygen flow independant of oxygen pressure and temperature, or ambient conditions. Float-in-tube flowmeters are very sensitive to gas pressure and temperature. The mass flow controllers may be monitored as part of option PC-30 or PC-60m, above. |
|
CH
|
Recirculating chiller for the condenseer water eliminates water water. it is particularly suitable for hot environments when cool water is not available. The chiller can be only used when the condenser water is connected in series with the other condensers. |
|
CH-3
|
Same as option CH, but the chiller has sufficient colling capacity to cool condenser water for all 30 positions and is provided with 3 individual recirculating pumps. Each pump recirculates the chilled water to a group of 10 condensers. The chiller can only be used when a back of 10 condesers are connnected in a series with the other condensers. |
|
CH-5
|
Same as option CH-3, above, but with pumps and the capacity to cool 5 groups of 12 condensers in each group arranged in a series. |
