Model 315i is available as a set with a DurOx 325 probe or with a CellOx® galvanic DO probe. The DurOx probe has a thick durable membrane which requires very low flow rate and is ideal for aquaculture and educational applications. The CellOx® probe has a thin PTFE resin reinforced membrane with a rapid response, and is optimized for water/wastewater applications.

Model 330i offers the same features as the 315i and more. Calibrate by air calibration or to titrated values. Measure O2 partial pressure in mbar. Time controlled datalogging of 800 GLP data sets. 330i meter set includes CellOx® galvanic DO probe.

Model 3400i adds additional features to the 330i. Operates on battery or 110V power. Bidirectional RS232 and analog interface. Order Pilot software for easy data download to a computer. 3400i meter set includes CellOx® galvanic DO probe.
