pH Bench Meter – XS8+


Our best selling pH bench type meter is an economical model that features Digital High Sensor (DHS) technology.
Includes pH, mV, temperature, GLP, connections for USB Data Logger and RS-232 printer.

pH measurements are frequently performed in many fields, including the water, food and pharmaceutical industries.

The XS8+ pH Bench Meter is ideal for everyday use in laboratories, with its intelligent sensor, large display and arm stand.

What is Digital High Sensor (DHS)?

Digital High Sensors are new pH sensors that are fitted with an internal chip that stores parameters, date of last calibration, model and production batch of electrode.

This data is transferred from the sensor to the instrument when connected.

If this electrode is moved to another DHS-enabled instrument, one can start working immediately and securely, as the data from the last calibration will automatically be transferred and used for pH measurements.

The XS pH Bench Meter also has the capability to work with both the new DHS digital sensors and normal analogue sensors.


Industrial labs, process / waste water testing, quality assurance testing, food testing, cosmetics industry, metal industry and educational institutions.
