505-8a is an liquid bath with 8 test positions accepting ASTM D2893 test tubes and with 8 float in tube flowmeters delivering oxygen at 10 ±0.1 L/hr. Useful temperature range is from 40º C up to 250º C.
The heavily insulated stainless steel bath is agitated by an electrical motor for temperature uniformity. An over temperature cut off circuit is provided in the event of primary controller failure.

Model 505-4a is similar to Model 505-8a but with only 4 test positions.
