In-Line Sensors - Van London

	Model P821 Sensor Specially designed for convenience of electrode replacement where minimal troubleshooting and maintenance downtime are of prime importance. The P821 is suitable for virtually all applications where a high performance sensor is required, either in-line or submersible installation. The electrode features a detachable cable with an integral preamplifier which eliminates any ground loop problems. The preamp converts the high impedance signal into a stable, noise free signal.
	Threaded pH/ORP Sensors These inline pH and ORP electrodes are designed for mounting on standard 1” or ¾” pipe tees for continuous pH or ORP flow-through monitoring. They are constructed with a sealed solid polymer reference which requires no pressurization or refilling during use. With the large reference surface area, reference clogging is not a problem.
	Tuff-Fet & Transmitter Non-Glass pH Electrodes The Tuff-Fet™ sensor is a solid state, ion selective field-effect transistor or ISFET. This technology does not require a glass membrane, making it perfect for Food-Grade Applications.
	Twist-Lock Series For pH Or ORP Applications The Twist-Lock™ sensor and adapter is designed to convert a standard pipe tee into a low cost, low maintenance flow-through sensor assembly. Only a ¼ turn is required for field maintenance or sensor replacement; threading is eliminated. The adapter is available in a variety of materials & connection sizes for easy installation.
