Ion Specific Electrode (ISE) Sensors
Get direct, ion-specific measurement of chloride concentration in groundwater.
Explore how ISE sensors work on your site:
Data Acquisition & Connectivity
All sensor data is logged to onboard durable flash memory and transmitted in real time over LoRaWAN with no risk of data loss during communication outages.
In-Situ Groundwater Chloride Sensing
Our sensor measures chloride ions directly using solid-state ion-selective electrode (ISE) technology.
Multi-Channel Solid-State ISE Array
The sensor employs multiple channels of solid-state ISEs engineered for chloride selectivity.
Microfluidic Sample Handling
The sensor uses a microfluidic flow cell that consumes approximately 150 microlitres per measurement cycle. Between measurements, the flow cell executes a wash and air-dry sequence that maintains the ISE sensing surfaces, preventing fouling and prolonging electrode life, enabling up to 365 autonomous measurement cycles on a single deployment.
Autonomous In-Field Calibration
Our sensor addresses electrode drift directly by performing a full calibration cycle during every measurement using sealed calibration standards housed within the sensor body.
Serviceability
At the end of a deployment cycle, sensors are returned and factory-reserviced keeping sensors in continuous rotation while maintaining factory-grade measurement quality.
LiORA’s sensors are supported by our modelling platform
Get the real-time and predictive insights you need to make data-backed decisions.
Features
In-Situ Groundwater Chloride Sensing
Where many competing approaches rely on electrical conductivity as a proxy for chloride, our sensor measures chloride ions directly using solid-state ion-selective electrode (ISE) technology.
Autonomous In-Field Calibration
Electrode drift has historically limited ISE sensor viability for long-duration field deployments. Our sensor addresses this directly by performing a full calibration cycle during every measurement using sealed calibration standards housed within the sensor body.
Microfluidic Sample Handling
The sensor uses a microfluidic flow cell that consumes approximately 150 microlitres per measurement cycle. Between measurements, the flow cell executes a wash and air-dry sequence that maintains the ISE sensing surfaces, preventing fouling and prolonging electrode life, enabling up to 365 autonomous measurement cycles on a single deployment.
Serviceability
At the end of a deployment cycle, sensors are returned and factory-reserviced. This exchange model keeps sensors in continuous rotation while maintaining factory-grade measurement quality.
