Retractable Lock-N-Load Sensor Assembly

All you need to do is Lock-N-Load to install a pH or ORP electrode into any pipeline. This is the first in-line assembly that doesn't require ball valves, cables, or costly, complex hardware to quickly insert or remove an electrode from a pipeline without interrupting the process.

Mark 7 Series For pH And ORP Applications (Hot Tap)

The Mark 7 insertion assemblies permit continuous pH or ORP monitoring in pressurized vessels or lines.
Specifications are for mounting onto a weldalet, a pipe tee or flange. To reduce the maintenance
downtime required, electrode connections terminate inside an explosion-proof junction box which houses
the preamp as well.

Mark X Pneumatic Retractable Sensor Assembly For pH And ORP

The Van London Co. (aka Van London pHoenix Co.) Mark X Pneumatic Retractable pH / ORP Sensor Assembly permits continuous pH or ORP monitoring where service must be performed without process interruption. It can be mounted vertically or inclined in reactors of pilot and production plant facilities.

Mettler (Ingold®) Direct Replacements

This new line of direct replacements for Mettler Ingold®-style electrodes is now available for a wide variety of pH or ORP applications. They are designed dimensionally to retrofit with existing installations. Expensive equipment changes are no longer necessary.

Micro Autoclavable Electrodes

This series of miniature steam sterilizable, combination pH and redox electrodes are designed for small bench top fermentors and culture apparatus. The electrodes are designed to fit all 12mm and 6mm electrode holders or rubber stoppers used in bench top fermentors.

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.

pHastTrac® 2000

The proven design of the pHastTrac® 2000 is ideal for applications in the food, process, pharmaceutical and many other industries where frequent cleaning and calibration of the pH and/or ORP electrode is required. Incorporated in this system is a clean / cal chamber that allows the user to remove the electrode from a process line or tank while maintaining production integrity.
