Wireless ISFET pH Meter Kit for Agriculture and Horticulture
A full kit for fields use and in the greenhouse with the same ISFET multi parameter meter as the single ISFET pH. The kit has the following components:
- FieldScout wireless ISFET pH and Temperature Meter
- Calibration solutions pH 4, pH 7
- Predrill stick for use in heavy and sharp/gritty soils
- Cleaning brush
- Carrying Case
The probe has an ISFET pH sensor and a 4-electrode EC sensor for measuring the parameters. Each meter consists of a probe part and a bluetooth transmitter part. The probes are replaceable. The transmitter can be used with different Sentron probes. By connecting the meter to your smartphone, you can configure measure, calibrate using the Sentron app on your smartphone. The app is free of charge.
Few characteristics:
- Robust in comparison to glass electrodes
- Very accurate and durable in soil, water and food or other samples
- BLE (Bluetooth Low Energy) wireless connection with your smart device via free FieldScout pH App.
- Wireless chargeable battery
- RGB LED for status update and recognition to cloud-based application
- Temporary data storage when non-connection with smart device takes place.
ISFET pH Sensor
This is pH measurement without the common glass electrode. The Sensitive Field Effect Transistor (ISFET) sensors are robust abd extremely accurate and now also for use in agricultural applications.
Wireless Connection and Use of Free App
Use the meter with the free FieldScout pH App available in your app store. By connecting the meter to your smart device measurements are shown directly in the free FieldSout pH app. The app makes use and analysis possible wherever you are and is able to accomodate 6 different ISFET meters..
Specifications of the App:
 |
- Calibration, obtaining, visualisation, storage and export of data
- Up to 6 wireless ISFET probes connected for simultaneous measuring
- Real-time notifications when pH-values are out of range
- GPS location basede pH map in Google Maps
- Language: English, Dutch, German, Swedish among others. iOS and Android

Application
The probes are and can be used in various samples, e.g. food and agriculture. We would like to note that for specific usages in field applications caution should be taken into account when sharp objects in the soil are present.
Sharp grit, rocks or sand present in the soil asks for the use of a pick or screwdriver to predrill a hole before penetrating the probe into the soil. The transistor can be damaged by sharp objects. Potting soils and other soft(er) media the probe can be inserted without problems.
Models
Two models are to choose from matching your specific use:
- Sharp Tip. Suitable for direct insertion of the probe in firmer media and samples
- Round Tip, rounded flat tip. For applications where forceful penetration is hardly needed.
