pH kit Analog Front-end module

The conditions for purchases, deliveries and returns are described in our Terms and Conditions.
  • Article number: A120-003
  • Provides analog voltage output pH signal when the pH-kit ISFET pH sensor module (A120-001) and the pH-kit reference electrode (A120-002) are attached
  • The analog output will require the user to develop his own calibration algorithm that converts the mV output signal into a meaningful pH value.
  • Core module with an uncalibrated analog pH output signal (voltage output 0 — 3.3V with ~ 52 mV / pH and pH 7 between 500 and 1800 mV)

Probably also good to add


Analog Front-end module for the pH-kit. Provides an analog voltage output pH signal when the pH-kit ISFET pH sensor module and the pH-kit reference electrode are attached.

Please check our technical guide before use.

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
