No other units of measurement are included in this standard. Measurement of Static Non-Flowing Samples. LTH is celebrating 50 years. Link to Active This link will always route to the current Active version of the standard. 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.

Conductivity measurement from 0. Download Data Sheet Download Handbook. The AquaCal overcomes this problem by providing a portable calibrated system that can be used to check on-line instrumentation by comparison. The following test methods are included: These include dissolved electrolytes in natural and treated waters, 1d125 as boiler water, boiler feedwater, cooling water, and saline and brackish water.
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. The temperature compensation is selectable in or out, with a fixed curve compensation for ultra pure water and a selectable slope of 0.
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. Call Email sales lth. 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 intelligent c1125 solution.

Historical Version s – view previous versions of standard Translated Version s: Collection of the water sample is atsm due to possible contamination from CO2 or other ionic materials. Downloads Click here to view our list of available downloads.
The cell has been designed for direct insertion into a process line or into a flow chamber for a sample stream. These test methods may also be used for checking the correctness of water analyses 5. Historical Version s – view previous versions of standard. The instrument is powered atsm either standard AA alkaline or NiCad rechargeable batteries.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Ideal for validation of pure water treatment d115 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.
The AquaCal incorporates the correct temperature compensation matrix for the ionisation of water as well as the contribution from ion mobility. Visual diagnostics indicate instrument and sensor faults and incorrect configuration by a series of error messages.
Alternatively where mains power is available the battery charger can be used to power the instrument.
The AquaCal instrument has the facility to enter the actual calibrated cell constant value, minimising any errors introduced by the cell. Ask the Experts If you have a liquid measurement application you would like to talk to us about click here to contact an expert.
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.

Please select your language. It is the user’s responsibility to ensure the validity of these test methods for waters of untested matrices. The AquaCal measures both nontemperature compensated and temperature compensated conductivity or resistivity to meet the current USP United States Pharmacopoeia requirements.
The temperature effects on the conductivity of pure water are large and non — linear.
