    2.2 Set Salinity This option allows you to set the salinity (in ppt) for your solution, as the dissolved salts alter the relationship between the partial pressure of oxygen and the oxygen concentration in water. By setting the salinity, the meter will compensate for the impact of salinity on the partial pressure/oxygen concentration relationship of your sample.

  • Page 122: Appendix

    1. APPENDIX 1.1 Conductivity theory Conductance is a quantity associated with the ability of primarily aqueous solutions to carry an electrical current, I, between two metallic electrodes when a voltage E is connected to them. Though water itself is a rather poor conductor of electricity, the presence of ions in the water increases its conductance considerably, the current being carried by the migration of the dissolved ions.
  • Page 123 The salinity scale which ranges from 0 to 80 ppt is a measure of all salts, not just sodium chloride. This scale was originally devised for seawater, and is based on seawater at 15 degrees Centigrade has a conductivity equivalent to that of a potassium chloride solution of a known concentration.

  • Page 124: Calculating Tds Conversion Factor

    1.2 Calculating TDS Conversion Factor You can calibrate your meter using TDS calibration standard solutions. The calibration standard only needs to give the TDS value at a standard temperature such as 25 °C. To determine the conductivity-to-TDS conversion factor use the following formula: Factor = Actual TDS ÷...

    1.4 Dissolved Oxygen Probe 1.4.1 Dissolved Oxygen Principle The probe is a galvanic measuring element which produces an output proportional to the oxygen present in the medium in which it is placed. The galvanic probe design lets you take measurements immediately – without the typical 15 minute wait of other dissolved oxygen probes.

Typical membrane damages are punctures or wrinkles caused during measurements or cleaning. Your new DO probe comes with replacement membrane housing. To order more replacement membrane housing, see the “Accessories”...
