The cell has been designed for direct insertion into a process line or into a flow chamber for a sample stream. Alternatively where mains power is available the battery charger can be used to power the instrument.
The temperature effects on the conductivity of f1125 water are large and qstm — linear. Collection of the water sample is critical due to possible contamination from CO2 or other ionic materials.
Link to Active This link will always route to the current Active version of the 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. The intelligent measurement solution.
The instrument is powered from either standard AA alkaline or NiCad atm batteries.
The temperature compensation is selectable in or out, with a fixed curve compensation for ultra pure water and a selectable slope of 0. Visual diagnostics indicate instrument and sensor faults and incorrect configuration by a series of error messages.
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. The AquaCal measures both nontemperature compensated and temperature compensated conductivity or resistivity to meet the current USP United States Pharmacopoeia requirements.
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 0. Please select your language.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. No other units of measurement are included in this standard. The following test methods are included: The AquaCal instrument has the facility to enter the actual calibrated cell constant value, minimising any errors introduced by the cell.

The AquaCal overcomes this problem by providing a portable calibrated system that can be used to check on-line instrumentation by comparison. 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.
The AquaCal incorporates the correct temperature compensation matrix for the ionisation of water as well as the contribution from ion mobility. The AquaCal has isolated voltage outputs, which can be used with a data logger or asym to provide a permanent record of conductivity, resistivity or temperature.
