S200 Series - Low Cost Submersion and In-Line pH Electrode

S200 Series - Low Cost Submersion and In-Line pH Electrode

This series of electrodes is designed to provide an economical multi-purpose solution for in-line or submersion pH measurements. Based on our proven S200C bulb and S350CD flat surface pH glass technology, these rugged and durable electrodes are available in Ryton nipples with 1/2" or 3/4" NPT threads; or in our durable epoxy body with or without quick disconnect top caps. Choose from single or double junction designs, flat or recessed measuring surface configurations and cable lengths and connectors as required.
