Description 

The measurement is based on the pH-difference method described in DIN 38404-10 : 1995-04 Calcit saturation of 

water. Automatic zero-point calibration of the pH-difference measurement. Reaction time in the marble filter 

controlled by stepmotor-driven peristaltic pumps Two separate controllers both of which can be assigned to the pH 

value of the incoming water or after the marble filter or to the pH difference. 

Particular characteristics 

2 limit values with delay, assigned to alarm relay for pH value or difference 

2 separate PID controllers for pH value or difference 

Automatic zero calibration of the pH difference in adjustable time interval 

Semi-automatic two-point-calibration 

Manual or automatic temperature compensation by integrated Pt100

pH buffer solutions 

The slope of pH sensors changes over the time 

(depending on the measuring media). We recomment 

a regular calibration with our buffer solutions. We offer 

1000 ml packages of pH 2, pH 3,56, pH 4, pH 7, and 

pH 9,22, and 50 ml packages of pH 4, and pH 7.

201012100 The sensor of the Zirkon pH series are highly 

sophisticated sensors with a high value for money 

ratio. They are used in many applications e.g. 

industrial, process and waste water. We use our high 

performance AH glass with low alkaline error and a 

broad temperature range. We use a high class 

ceramic junction which increases the sensor life 

expectancy and our low maintenance Topax gel. As 

reference system we use a cartridge system which 

results for a constant measurement especially in 

applications with high temperature fluctuations.

Neon Touch wall mounted housing 

Description 

Neon is a modern measuring and control instrument, whose scope of functions you can determine according to your 

application. The basic version contains inputs for measurement and temperature, key operation, one digital input 

and one alarm relay. Via codes and add-on modules you can add one or two analog outputs, control functions either 

concentration-based or volume-based, as well as various digital output functions such as modbus interface, 

Ethernet, webserver, or datalogger. You can even adjust what information you want to see in the display. And if you 

have to install more than one instrument of the same type with the same settings, settings can easily be multiplied 

via SD card. Use the full advantages of the graphical menus with our touch screen version Neon Touch! Neon pR is 

used for pH and ORP measurements.

We use different materials like ceramic or glass sleeve as junction. The junction and the electrolyte are determine 

the salt output and therfore the measurement quality in ion poor media. As electrolyte we use our 3M KCl - this is 

refillable. As reference system we use a cartridge system which results in a constant measurement especially in

Description 

206051320 

Sensors of the Zirkon pH coating series are developed for the use in lacquer and coatings. They are used in paint 

and coating industry. Crucial for the measurement in coatings is the contamination of the junction. This mainly 

determines the life expectancy of the sensor. In case of the Zirkon pH coating sensors the projecting junction can be 

protected with a membrane or a hole is used in combination with solid electrolyte instead of a junction.

AH-200-K 

The pH electrode AH-200-K is a single measuring 

electrode. To measure pH, it has to be used in 

combination with a separate reference electrode. 

Combination electrodes with integrated reference are 

easier to calibrate and to install, but in very 

aggressive solutions that shorten the life time of either 

the reference or the measuring electrode, it might still 

be advantageous to use separate measuring and 

reference electrodes.
