pH Sensor DGi115-SC

Acid-base Titration in Food & Beverages.Optimized for food quality analyses. DGi115-SC is a combined glass pH electrode with a fixed ground-glass sleeve junction and Plug & Play functionality. Especially designed for stable measurement signal and easy cleaning.

Reliability Guaranteed

Sensor and calibration data stored in the sensor chip are always up to date and monitored, guaranteeing the sensor is always in good condition.

Controlled Clean Conditions

The ARGENTHAL™ reference system's silver ion trap keeps the reference electrolyte free from silver ions with no danger of food clogging the diaphragm.

Fast Response Time

The HA glass pH membrane features rapid response time, low alkali error, and outstanding mechanical durability. Consistently high performance.

Repeatable Precise Results

Electrolyte flow through the fixed glass junction is constant and guarantees accurate and reproducible pH readings and end point titrations. Any food ingredients that stick to the glass surface can be cleaned off easily.

Designed for Food Applications

The large sleeve junction provides a stable measurement signal thanks to a uniform flow of electrolytes. The junction is easy to clean and difficult to clog with precipitates.

Application Examples

Media with low ion concentration (e.g. low ion conductivity water). Polar solvents such as acetic acids or alcohols (e.g. titration with perchloric acid in acetic acid or with sodium methylate in methanol).

Precision and Reliability

The combination of experienced craftsmanship plus maximum utility of automated production methods ensures consistently high sensor performance.

Guaranteed Quality

No sensor leaves the production facility untested. Only after a series of demanding final checks does each sensor receive its individual quality certificate, ready for dispatch.
