The temperature compensation is selectable in or out, with a fixed curve compensation for ultra pure water and a selectable slope of 0.
Historical Version s – view previous versions of standard Translated Version s: The following test methods are included:. Link to Active This link will always route to the current Active version of aztm standard.
Measurement of Static Non-Flowing Samples. Historical Version s – view previous versions of standard. The AquaCal hand held system has been developed to provide a method of measuring the conductivity or resistivity of pure water to traceable standards making it suitable to validate pure water treatment plants.
No other units of measurement are included in this standard. Downloads Click here to view our list of available downloads. Currently it is only possible to calibrate instrumentation on site by using precision resistors, however it is impossible to check the complete measurement system including the cell. Ideal for validation of pure water treatment plants Scaleable voltage outputs for conductivity, resistivity or temperature Alkaline or NiCad rechargeable batteries or mains adaptor operation User selectable security code to protect settings and configuration Diagnostics to indicate instrument and sensor faults and incorrect configuration.

Collection of the water sample is critical due to possible contamination from CO2 or other ionic materials. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The system consists of a precision conductivity cell with a certified cell constant to ASTM D and BS and a microprocessor instrument that has been calibrated against ashm. The AquaCal incorporates the correct temperature compensation matrix for the ionisation of water as well as the contribution from ion mobility.
The temperature effects on the conductivity of pure water are large and non — linear. The AquaCal instrument has the facility to aetm the actual calibrated cell constant value, minimising any errors introduced by the cell.

The following test methods are included: The instrument is powered from either standard AA alkaline or NiCad rechargeable batteries. These test methods may also be used for checking the correctness of water analyses 5.
Alternatively where mains power is available the battery charger can be used to power the instrument. The AquaCal measures both nontemperature compensated and temperature compensated conductivity or resistivity to meet the current USP United States Pharmacopoeia requirements.
The intelligent measurement solution. 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. It is the user’s responsibility to ensure the validity of these test methods for waters of untested matrices. Download Data Sheet Download Handbook.
ASTM D – 14 – Standard Test Methods for Electrical Conductivity and Resistivity of Water
These include dissolved electrolytes in natural and treated waters, such as boiler water, boiler feedwater, cooling water, and saline and brackish water. The cell has been designed for direct insertion into a process line or into a flow chamber for a sample stream. The AquaCal overcomes this problem by providing a portable calibrated system that can be used to check on-line instrumentation by comparison. Visual diagnostics indicate instrument and sensor faults and incorrect configuration by a series of error messages.
