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.

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.

This series of steam-sterilizable pH and ORP electrodes are designed for small fermentors where sterilization is performed in an autoclave in non-pressurized operation. The electrodes can withstand repeated sterilization up to 130°C and feature a detachable cable assembly insulated with a water tight connector.

Van London Co. Rosemount® pH replacement sensors have been field proven in a variety of harsh applications. An inventory stocking arrangement reduces lead times from weeks to days. Housed electrodes generally consist of two parts: a 12mm glass-bodied electrode and housing machined to accept that electrode. Minimal factory assembly is required before shipment to the customer site.

This new generation, low cost, steam sterilizable insertion sensor is specifically designed for low maintenance requirements.   The assembly is low profile and features an easily replaceable, sealed, combination pH or ORP electrode.

The low profile design allows the process flow to clean the pH / ORP sensor tip, and with the addition of the Van London Co. Tuff Tip™ the bulb is protected from physical damage.

The Van London Steam Sterilizable Carbon Dioxide probe is specifically designed for fermentation applications where it is necessary to subject the electrode to repeated steam sterilizations.
