R&D evaluation ISFET pH kit

The conditions for purchases, deliveries and returns are described in our Terms and Conditions.

Article number: A120-200

Please check each individual item for its key features by selecting them above. The ISFET pH module and reference electrode module are to be wired directly to the Analog Front-end module. Use of the features of the AD converter module and the USB Interface module require knowledge of programming serial communication in embedded applications.

pH kit ISFET pH sensor module (A120-001)

  • ISFET (Ion Sensitive Field Effect Transistor) pH sensor: glass-free, robust and dry storage capabilities
  • PT1000 temperature sensor

pH kit reference electrode module (A120-002)

  • Gel-filled reference chamber for stable and accurate pH measurements

pH kit Analog Front-end module (A120-003)

  • The analog output will require the user to develop his own calibration algorithm that converts the mV output signal into a meaningful pH value.

pH kit AD Converter module (A120-004)

  • This module is optional and has to be connected to the pH kit Analog Front-end module.
  • This extension module with microprocessor, AD Converter and galvanic isolation makes it well suited for use in embedded applications.

pH kit USB Interface module (A120-005)

  • This optional module has to be connected to the AD Converter module.
  • By this module it is possible to request measured pH and temperature values from a laptop or PC with a USB port (USB 1.1 or 2.0).

Buffer set (pH 4, 7, 10 and rinsing fluid)

  • This is a free sample of the most used Sentron buffers: 60 ml bottles with buffer pH 4, pH 7 and pH 10, as well as rinsing fluid
  • The buffer solutions are N.I.S.T. based, high quality reference fluids

Wireless and durably interchangeable

Wireless and durably interchangeable, our premium pH probe enables you monitor this essential parameter in whatever application, whenever you want, wherever you are.

Frequently Asked Questions

Thanks to the ISFET technology the pH sensors are robust and can be stored dry. This has a great benefit for applications like water quality measurements in stream beds and tidal areas, where the water level changes in time and the probe will occasionally be above the water level. 

The glass-free approach makes the pH also available for inline food processes and medical applications like gastro-enterology, for which any glass splinter could be fatal.

The new product line is a wireless product line. No cable and thus more flexibility. No limitation of 1 probe per meter at a maximum 1,5 meter distance anymore! The Bluetooth connection enables you to have several meters within the mobile and the probe. Unlimited numbers of probes can be connected and read out simultaneously. Additionally the features of your phone can be used: GPS, social media, cloud service, etc.

Additionally we’ll release a multisensor on the market in the near future. This probe for pH, EC and ORP can be added up to the number of probes connected to your mobile device.

The connection between the probe (/transmitter) and the mobile phone is dependent on the Bluetooth signal. We have used a powerful approach for this, enabling a distance of maximum XX meter through the air. 

Let’s get connected and see whether we have a match. Please refer to / and we’ll contact you as soon as possible.

Besides the standard product line we are also providing contract development and contract manufacturing of sensor assemblies. More information on this is provided at Sensor Integration Services
