ISE sensors for measuring ammonium, nitrate or chloride in fresh water are now available for the well-established HYDROLAB HL4 and HL7 probes.
ISE stands for „ion-selective electrode“ and describes a sensor that converts the activity of a certain ion dissolved in water into an electrical potential. The newly introduced ISE sensors for ammonium, nitrate and chloride from HYDROLAB are robust and work in water depths of up to 15 meters.
The ammonium and nitrate sensors can measure in a range from 0 to 250 mg/L-N and the chloride sensor from 0 to 18,000 mg/L. They have an accuracy of ± 10 percent and can be used in an ambient temperature range between 0 and 40 degrees Celsius.
In general, ISE sensors have a higher drift than other water quality sensors. Therefore, they are especially suitable for spot measurements where the sensors are calibrated prior to the measurement campaign. Frequent quality checks and re-calibrations are required for longer periods of use. The HYDROLAB probes HL4 and HL7 support the user with a sophisticated maintenance and information concept. When connected to the operating software, the probe uses status displays to indicate whether calibration of the respective sensors is necessary. Calibrations can be carried out quickly and easily using guided calibration routines.
