This article discusses a newly developed silver‐silver chloride electrode and a standard pH meter that provides a simple and accurate means for the field determination of chloride concentration. The electrode contains a billet of silver chloride, with a large part of its surface area exposed to the sample. In this respect it differs from earlier electrodes, which exposed only a small filament of silver chloride and were not rugged enough for field use. The new electrode is used with a saturated calomel reference electrode. The procedure is discussed, along with theory and results of measurements, and errors and limitations.
