Epoxy Body Bulb Electrode – FLS pH/ORP 200
The FLS line of pH and ORP electrodes offers a cost-effective, multi-purpose solution for in-line or submersion measurements across a wide range of applications. Available in single and double junction versions, these electrodes can be supplied with or without quick-disconnect top caps. For automatic temperature compensation (ATC), a pH model with an integrated temperature sensor is also available.
Constructed with durable epoxy bodies, these electrodes deliver excellent chemical resistance, making them suitable for varied applications. Installation is simple—economic in-line mounting can be achieved with a reusable gland, while submersion mounting requires only a ½” or ¾” coupler with pipe extension. A special version is also designed for direct installation on FLS T-fittings or FLS clamp saddles with just the addition of a nut.
