The OZONE GENERATOR BMT 803 BT (Bench Top) is a mall, air cooled ozone source for laboratory applications. Operation is from oxygen. The instrument contains every con- trols and displays necessary, and desirable, for operating the ozone generator, except of an ozone analyser. A special exter- nal ozone analyser BMT 964 can be connected to two sample gas fittings at the rear of the BMT 803 BT. This in-line ozone analyser carries the complete ozone gas flow and thus does not consume any ozone gas for its operation.

The oxygen mass flow meter is independent of the pressure and temperature of the oxygen. Displayed is the oxygen flow in Nl/min, one Nl/min equaling 85.7 g/h.

The ozone-resistant pressure gauge behind the outlet needle valve shows the ozone system counter pressure, the pressure into which the ozone gas is flowing.

Dimensions of the OZONE GENERATOR BMT 803 BT are 255 x 200 x 385 mm (10” x 8” x 15”). The weight is 10 kg. Input voltage is 230 VAC, or 115 VAC. The oxygen inlet fitting (on the rear) is for 4 x 6 mm (or 1/4" x 5/32") PTFE tubing. The ozone gas outlet fitting (on the front panel) is for 3 x 5 mm (or 1/8” x 3/16”) PTFE tubing. Power consumption is 170 W max.
