FAQs

No, all our sensors are calibration-free

No, our ground-breaking technology negates this common issue

Yes, all our sensors are CE certified

Yes, our sensors are fitted with an integral 8GB memory card allowing in excess of 15 million data points to be collected

During the measurement, a low concentration of biocide is produced locally to the transducer. Extensive testing has shown that this is enough to keep the transducer clean, another factor that sets these sensors apart from other water quality sensors

Our sensors measure pH throughout the entire salinity range – from 0.025 ppt to 40 ppt without the need to recalibrate

Our sensor’s fastest measurement rate is 17 secs

Yes, a user can fully configure the timing of operation and the measurement rate

The time required depends on the salinity. The first measurement takes between 1.5 to 3.5 minutes as the sensor performs reference checks to ensure a calibration-free reading. After that, measurements are taken every 17 to 25 seconds.

Yes, set on user programmable timer or when immersed in water

Our sensors have been designed so they are very low maintenance – no calibration! The only maintenance that is required is an abrasion of the surface of the transducer after around 75,000 measurements. A video on transducer abrasion can be found here

The transducer will require replacing after c.300,000 measurements

No, our sensors have been designed for minimal maintenance and simplicity of operation, the transducer is easy to replace in the field

Our sensors are intelligent devices, constantly checking themselves, and will notify operators when maintenance or replacement is required with a Health Number. More information on this can be found here

Yes, this can be found here

No, our sensor can be stored wet or dry, setting itself apart from today’s glass electrode technology

Data can be streamed through 232/485 comms using either Modbus or our utils terminal program

Data is stored internally with our sensors to an integrated SD card capable of saving >15 million measurements of pH, temperature and conductivity. All data can simply be downloaded when the sensor is retrieved or accessed via a communications medium

All our sensors are pressure tested to 2x stated depths range, our maximum unit is currently 1250m, however, we are looking to deploy a 3000m unit in the near future

No, all our sensors can operate in either environment.

Our sensors are easily configurable and delivered with the transducer installed. Sensors are configured to continuous monitoring on delivery and can be custom configured and ready to go within minutes of power-up

Our sensors have a profiling mode which allows a faster response to pH changes, with an accuracy of +/- 0.1 pH unit
