Yokogawa provides several types of holders, for which cleaners can be added, allowing customers to build reliable and easy-to-maintain measuring systems by selecting the right holders and cleaners for the conditions of applications.

The submersion type holders PH8HS, PH8HSF and DOX8HS are widely used with process analyzers and can be directly immersed in reaction tanks or measuring baths for measurement.

The flow-through type holders PH8HF, PH8HFF and FH350G can be set up at a point along pipelines to measure solvent in production lines or wastewater pipelines.

The suspension holder HH350G has a guide pipe along which just a fitting mounted electrode can be separately pulled up with a chain, thus increasing the ease of maintenance.

The inclined float holder, PB350G is equipped with a float that moves up and down in accordance with the fluctuating water surface level. Since the float has been designed to accommodate an electrode without extreme projections and depressions, the amount of foreign matter building up around the float or electrode decreases, and it becomes harder for dirt to accumulate, thus enabling continuous stable measurement over a long period.

We have provided the vertical float holder, PB360G, for cases when the installation space for a float holder is limited or the measuring bath is covered.
