If the measuring instrument is provided with lations are necessary if the compensator is corrected for the a manual temperature compensator, adjust this to the sample solution in the cell. Protect the sample to avoid gain or facturers instructions and periodically check the instrument. Make sure that the conductivity readings are recheck the cell constant when received.

These include dissolved electrolytes in natural and treated waters, such as boiler water, boiler feedwater, cooling water, and saline and brackish water. These tabulated conductivity values are in international units. Calibration may be in either conduc- ing of the cell or a build-up of filming amines may cause poor tivity or resistivity units.
Contact with air should be avoided by using ate combination of a-c drive voltage, wave shape, frequency, flow-through or in-line cell where feasible. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Instruments shall energize the such as boiler water, boiler feedwater, cooling water, and saline conductivity cell with alternating current and, together with the and brackish water.

These test methods cover the determination of the electrical conductivity and resistivity of water. Read sample on three different days.
Reagents or dip cells can also be used. Standards Australia International, Ltd. The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
The AquaCal overcomes this problem by providing a portable calibrated system that can be used to check on-line instrumentation by comparison. Unless otherwise indicated, it is intended that protected by an inert gaseous layer of nitrogen or helium.

The AquaCal has isolated voltage outputs, which can be used with a data logger or recorder to provide a permanent record of conductivity, resistivity or temperature. Temperature control and correction composition caused by loss of volatile constituents or by methods are also provided. This standard has been approved for use by agencies of the Department of Defense. The intelligent measurement solution.
