Endress+Hauser CA80HA Water Hardness Analyser
The Endress+Hauser Liquiline System CA80HA hardness analyser provides online analyses of water hardness in drinking water and process water. It aids control of water softening processes such as ion exchange or reverse osmosis, determines the quality of products influenced by water hardness and analyses feedwater used in boilers.
The CA80HA colorimetric analyser uses the phthalein purple method, providing direct comparability to lab results. It measures calcium carbonate (CaCO3) over a range of 0 to 80 mg/L with accuracy of ±0.5 mg/L. The analyser has up to two measuring channels and up to four digital inputs for optional Memosens sensors such as pH, ORP, conductivity, oxygen, chlorine and turbidity.
The optional sensors can measure and calculate pH from two conductivity values according to the CGB Standard 405 for boiler feedwater. The sensors can also measure the difference between two assigned values from different sources to monitor membranes and calculate differential conductivity to monitor the efficiency of ion exchangers.
Outputs from the CA80HA can be used to directly control water processes as the process variables in a control loop, be assigned as a measured variable to a limit contactor, trigger cleaning, be sent to a control system for further analysis and be displayed on the local graphic readout. The local graphic display has 240 x 160-pixel resolution, a red display background for alarms and user-definable measuring menus.
The CA80HA meets the requirements of harmonised European standards and Canada and USA standards: CAN/CSAC22.2 No. 61010-1-12 UL Std. No. 61010-1 (3rd Edition).
