Field-installation type calcium ion meter

HC-200CA

For treatment of hydrofluoric acid wastewater from semiconductor production.

Contributes to reduction of chemical usage in the wastewater treatment process by continuously monitoring calcium ion concentration in the tank. Running costs and risk of scale generation are reduced by optimizing chemical usage, thereby contributing to stable plant operation.

Stable measurement

Using the ion selective electrode has made possible the stable monitoring of calcium ion concentration.

Lower running costs

Reduction of chemical consumption can be expected by controlling chemicals according to wastewater treatment status.

Reduced environmental impact

Contributes to the reduction of industrial waste by reducing the risk of sludge and scale generation due to excess calcium ions.
