Knick Indicators

Knick's third generation of loop-powered digital indicators which feed themselves from a low voltage drop from the 0 (4) to 20 mA current loop. Since power supplies and their wiring are omitted, the indicators are particularly suited for applications in hazardous locations. The new indicator series 830 uses latest microprocessor technology in redesigned enclosures that provide IP 65 protection even when mounted in a control panel.

Knick Portable Meters

The new portable meters for use with analog or MemoSens® sensors. The multiparameter device for pH, ORP, conductivity or oxygen (also optical oxygen). With graphical color display, and data logger. Its versitile functionality, robustness and the large selection of sensors make Partavo the perfect choice for both lab and process applications, even in hazardous areas.

Knick Process Analyzers and Controllers

With the modular Protos® 3400 (X) process analysis system for pH, conductivity and oxygen, Knick is once again setting new standards. Freely combinable measuring, communication, and controller modules as well as state-of-the-art asset management functions ensure unrivalled safety and flexibility.

Knick analyzers in 2- and 4-wire technology provide an unbeatable product range including PROFIBUS, FIELDBUS, and HART communication.

Knick Sensors (Including Memosens®) and Fittings

Measured-value acquisition for every application: pH (both glass and ISFET), Conductivity (2/4 electrode cells and electrodeless), and Oxygen (sterilizable, autoclavable and CIP compliant).

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.

LpH

LpH - Non Glass pH Electrode for HF Applications

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.

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.

Rosemount® Replacements

Van London Co. (aka Van London pHoenix 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.

Sensorex® & Signet® Replacements

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

Submersible Sensors For pH, ORP & Conductivity Applications

The Mark I-A and Mark VI-B sensors will continuously monitor pH, ORP, and Conductivity in tanks, vessels, or canals where liquid levels tend to vary. Typical applications include chlorine cells, latex coagulation tanks, and effluent sumps. It can be installed in atmospherically sealed vessels with use of a tank mount fitting.

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.
