DULCOTEST® pH Sensors
Graduated pH measuring ranges 0 – 14
pH measurements with DULCOTEST® sensors: Precise, reliable and application-adapted measured values in real time. Control, regulate and monitor chemical processes with the aid of precise measured values.
Reliable online measurement of pH values – with DULCOTEST® sensors
The online measurement and adjustment of pH values must be as accurate, fast and reliable as possible, with high availability of the measured values, whether for the monitoring, control or regulation of chemical processes.
Our product line of DULCOTEST® pH sensors provides a wide range of pH sensors for different measuring tasks.
The production of our pH sensors is subject to very strict quality controls (e.g. in accordance with RoHS guidelines). Routine steps are automated but critical steps are carried out manually under expert supervision. In this way we achieve optimum reproducible quality and cost reduction.
Your benefits
Precise and reliable pH measurement enables efficient processes and maximum process reliability
The wide choice of sensor types with different constructions makes them reliable components in many applications
A long service life is achieved through the use of the best quality materials for the glass and diaphragms, a stable reference system and optimised production. This minimises both downtime and maintenance
With short storage times and fast delivery, your pH sensors can be up and running very quickly and you can make maximum use of their service life (all glass sensors start to age as soon as they leave production)
Wide range of special versions for fitting length, cable length and plugs for made-to-measure connection to your process
Unique label for OEM partners
Field of application
- Chemical processes
- Chemically contaminated water
- Swimming pool water, potable water
- Process water
- Cooling water, waste water
- Seawater
- Suspensions, sludge, emulsions
- Exhaust air scrubber, semiconductor industry, electroplating
Technical Details
Selection of sensor type according to the application
The insertion angle must be > 15° from the horizontal (except with PHEK-L: horizontal to vertical)
Maximum flow < 0.8 m/s
With cable lengths > 10 m, use the 4-20 mA transducer type PHV1
Calibration using quality buffer solutions
pH Sensor PHES 112 SE
pH sensor optimised for use in potable water treatment, swimming pools/hot tubs at up to 60 °C/3 bar
Your benefits
Electrochemical combination electrode: pH and reference electrode integrated
Diaphragm and reference system optimised for use in swimming pools and for potable water
Ceramic diaphragm with special material, optimised size and optimised pore diameter
Long service life due to reduced diffusion ("bleeding") of the electrolyte
Long service life due to the material, which is inert to aggressive disinfectants
Stable reference system
Twist protection for the sensor cable connected. This means that the cables can remain connected during installation and dismantling of the sensor, avoiding troublesome moisture on the connector contacts
