The versatile Model 546 is suitable for in-line sample stream applications using the 3/4 inch NPT process connection. A similar 3/4 inch NPT connection on the rear of the sensor is used to mount the sensor in submersible and high pressure hot tap installations. With tip lengths from 0.5 to 5.0 inches the 546 sensor can fit through extended pipe nipples and flanges to reach into the process and provide optimum pH/ORP measurement.

The Model 547 is a replaceable, cartridge style sensor. It is designed to fit into a variety of sensor holders for direct insertion into the process. When used with a metallic sheath the 547 sensor can provide variable insertion depth for hot tap ball valve installations as well as the ability to withstand pressures up to 2500 PSIG with Barben’s high pressure housing assembly.

In some in-line applications sensor removal for routine cleaning or calibration becomes difficult due to conduit or cabling. The 551 Quick Change Sensor offers a unique method to extract the sensor through a “Nut Lock” Adapter system. The Nut Lock Adapter threads directly into 1 inch NPT process connections. Sensor length options up to 12 inches allows the sensor to fit through flanges and stand-off piping. The 551 sensor also includes a 3/4 inch rear connection for use in submersible applications.

The Model 567 All Plastic Hot Tap Retractable Sensor. If your piping is corrosion resistant plastic, shouldn’t your pH sensor be the same? The Model 567 is specifically designed for use in the most aggressive measurement applications. It is the only “All Plastic” hot tap retractable pH sensor available to the market. The 567 sensor uses a Kynar insertion body thus eliminating the metallic sheath typically used with cartridge style hot tap sensors. Not only can it withstand strong chemicals; the Kynar body provides a great solution in applications that build-up and adhere to metallic parts.
