Free and Total Residual Chlorine Monitoring with Remote Access at Whitby Seafoods Ltd

Whitby Seafoods Ltd is an independent family business from Yorkshire that specialise in selling scampi. In 2019, Whitby Seafoods Ltd installed a residual chlorine monitor (HaloSense) and a CRIUS® controller, equipped with remote access from Pi.

The HaloSense from Pi measures free, total or zero chlorine. It uses membraned amperometric sensors that are enhanced with a third reference electrode to eliminate zero drift. The unique design means that pH correction is not required, eliminating the need for reagents and buffers. This contributes to the low cost of ownership that comes with the HaloSense. The HaloSense can be installed in a variety of auxillary flow cells and self-cleaning devices, making it the ideal tool for extremely challenging applications such as seafood washing.

“Since the installation of the Process Instruments controller, we have had great success in accurately maintaining a healthy free chlorine level in our borehole water. This along with the added online monitoring and email alarm system, has given us excellent peace of mind over the years”

 – Damon Wright, Senior Engineer and Whitby Seafoods Ltd

To reduce microbial contamination and transmission of foodborne illnesses, sodium hypochlorite is commonly used to clean seafood, or in this specific case, scampi. In the interest of consumer health, online monitoring of residual chlorine is vital to ensure effective disinfection. The HaloSense from Pi helps Whitby Seafoods Ltd. do this accurately and reliably. With the added remote access from the CRIUS®4.0 controller, engineers can view the instrument online and receive alerts and alarms via email, giving them access to the site without having to actually be there.
