Designed for applications where rough handling and breakage are major problems, the bodies of these electrodes are made from impact resistant epoxy tubing.

Particularly suited for use with portable pH meters in the field and to make spot check measurements of production processes.

Available with either Ag/AgCl or Calomel reference half-cells. The Ag/AgCI half-cell has the higher temperature rating, while the Calomel half-cell is recommended when measuring meats, broths, or any protein bearing sample.

Also available with either:

• liquid-filled/refillable reference or
• gel-filled/sealed reference

The gel-filled design offers excellent results with minimum maintenance. The liquid refillable design offers measurement accuracy and reproducibility approaching that of a glass laboratory electrode.

All polymer electrodes utilize a GP bulb glass, featuring fast response over the range of 0–12 pH.

All electrodes are completely shielded for a stable signal while being hand held.

All electrodes can be used continuously 0–80°C. The Ag/AgCl probes can be used intermittently up to 100°C.

• Offers excellent results with minimal maintenance.
• Large area, coaxial ceramic reference wick resists clogging and performs longer.
• All models also available with calomel half-cell or double junction.

A. Field pH Electrode, for Agricultural Process

Rugged field pH electrode. Rugged extra thick polymer wall (0.050") makes this the first choice for handheld field work. Dual ceramic pin wicks. 0-12 pH

B. General Purpose pH Electrode

General purpose design for both lab and field. Bulb guarded from accidental impact. Coaxial ceramic reference wick. 0-12 pH

C. pH Electrode with Removable Bulb Guard

General purpose design with a removable bulb guard. Coaxial ceramic wick. 0-12 pH

D. Long, Thin pH Electrode

Long, narrow stem design is ideal for measuring small samples in test tubes or narrow neck vessels. Ceramic pin wick. 0-12 pH

E. pH Electrode with Flat Bulb

Flat bulb pH electrode for measurements of moist, flat surfaces such as meat, agar plates and paper. Dual ceramic pin reference wicks. 0-12 pH

Primarily there are four things we need to know in order to correctly fill your order.

1. Electrode Model Number — Each electrode has a ten character model number.

2. Cable Type — All lab electrodes are equipped with Type A, low noise, 3 mm, coaxial cable. Place the A after the electrode number.

3. Cable Length — The cable length is expressed in feet immediately after the cable type. Example: "-A03" stands for a three foot cable which is standard for all electrodes in this catalog. Follow model numbers by a"-DK" for a threaded electrode cap.

4. Connector — The cable length is followed by a two letter designation for the proper connector. All connectors are available. If you do not see what you need on this page, give us the make and model numbers of your pH meter and we will supply the proper connector.
