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

  • ISFET (Ion Sensitive Field Effect Transistor) pH sensor: glass-free, robust and dry storage capabilities
  • Gel-filled reference chamber for stable and accurate pH measurements
  • Temperature compensated
  • To be connected to the (obsolete) SI meter by 1,5 meter cable before use
  • The successor for this wired probe is the LanceFET pH Probe.
See our SI serie LanceFET probes leaflet for all specifications.

Probably also good to add


SI serie LanceFET probe: Steel tipped probe for non-glass pH measurements after penetration of non-liquid samples like meat, fish, and fruits.

The probe is to be connected by cable to either the SI400 or SI600 Sentron pH meter. 

NB These meters are out of stock and not for sale anymore. The successor of these meters are the wireless pH probes that are connected by Bluetooth to any smartphone or tablet, iOS or Android.

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
