In-Line & Submersion (with a Housing)
Glass Body Sensors with PG13.5 Threads
The SP Series ProcessProbe™ electrodes are available for pH and ORP measurements. The SP Series electrodes are 12 mm x 120 mm with a threaded PG13.5 cap. These dimensions make them compatible with many pre-existing housings found in industrial and waste treatment applications. Like all ProcessProbes™, these electrodes are designed to work with Broadley-James transmitters and most other brands of existing instruments and cables.
The Double Junction Reference system used in all Broadley-James’ ProcessProbes™ reliably prevents process contaminants from fouling the reference. Since the reference is sealed, there is no electrolyte maintenance required.
Two glass formulations are available; HT-3 for general purpose pH measurements, or TX4 fluoride resistant glass for applications where hydrofluoric acid (HF) up to 1% concentration may be present. The TX4 glass formulation provides a useful lfe many times longer than standard pH glass sensors in the presence of acidic fluorides. Ideal for semi-conductor, glass etching,electroplating and waste water applications containg HF.
