DO/95002 DOS METER SCINET MODEL 347TX each £1029.60

The model 347TX is an advanced automatic dissolved oxygen meter with a robust splash proof case and the facility for both mains and battery operation.
The dissolved oxygen meter is ideal for BOD (Biological Oxygen Demand) measurements particularly when used in conjunction with the optional BOD funnel kit. The DO electrode is a classic Clark (or polarographic) cell and is extremely simple to prepare.
Polarisation is achieved in less than 2 minutes whilst the built in thermistor provides temperature compensation. Response and recovery rate are extremely rapid, reaching 98% in less than 60 seconds.
The model 347TX has 4 measurement modes; % saturation, ppm, temperature and the uncalibrated raw signal in microamps. This last mode is useful for investigating the permeability of different membranes such as packing materials. The instrument can be calibrated at 0% and 100% in water or air with a manual adjustment for atmospheric pressure changes. The meter has both a bi-directional RS232 interface and a recorder output for connection to external devices.
The meter comes complete with an electrode, stand, AC adaptor, 9v battery and a zero oxygen standard solution. Technical specification <
