I am Kay McGuinness from ANB Sensors. For the last 5 years we have been developing calibration free pH sensors for ocean/water monitoring. We are now ready to commercialise our sensor, which is small, adaptable, all solid state, but it’s main USP is that it doesn’t need calibrating. Most pH sensors suffer from reference electrode drift, which means frequent recalibration with known buffers. Our patented technology overcomes this issue and allows for smart, maintenance free sensing.
We had a trip to California in February to do the first trials of the ANB Sensors S1100 pH sensor on the BlueROV2. Kevin and Rusty were a great help, showing us the ins and outs of the vehicle, mounting and connecting the sensor.
You can see in the middle picture us polishing back the electrode head - this regenerates the sensor for further use - no calibration required! Then, after multiple uses, this solid state sensor head can be easily replaced (like an ink cartridge).
We hit some issues, mainly electrical noise related, but that’s what field trials are for isn’t it?
Anyway, since then, during lockdown, our electronics team have been busy overcoming this and results in our lab tank, using a Blue Robotics thruster, look really promising.
Now we’re looking forward to getting the sensor out there for real.
Are there any early adopters out there that want a fuss free, robust pH sensor that can be deployed easily on the BlueROV2?
