PRODUCT SPECIFICATION SHEET
Low Cost Submersion and In-Line
pH Electrodes
Economical design for in-line or submersion use
Choose from single or double junction models
Threaded 1/2" or 3/4" NPT connections
Choose from spherical or flat pH measuring surfaces
Special models for low ionic and other specialty applications
available
S270 Series Ryton Sensors
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. For special configurations such as low
ionic models, fluoride resistant pH glass and other specialty sensors, please contact the Sensorex sales or technical support
department.
