Holder for pH or ORP electrodes to install in line or as a by-pass.

Holder 9240 with suitable electrode allows in-line measurements of pH or ORP
under pressure.
Holder is suitable for electrodes with fitting PG 13.5 (see data-sheet 150-01).

For a pipe with a diameter greater than 25 mm, its installation must be done in a bypass, adding a pressure drop (restriction, elbow, valve, etc.) to ensure proper circulation of the liquid around the electrode. It is recommended to install valves, upstream and downstream of the bypass, to allow easiest calibration and maintenance routines.

For a direct on-line measurement, see the holders 9400 series (data-sheet 141.01).

Note: An average flow rate limit to respect is max. 500 l/h
