The HI981520-02 measures and displays conductivity, pH, and temperature for applications such as seawater, saltwater aquariums, and aquaculture. Parameters can be configured with alarms in high or low value mode, and the display is on a readable LCD screen.
The salinity of seawater can be expressed in g/L (ppt), in practical salinity units (PSU), or in specific gravity (S.G.). The probes attach to the back of the aquarium using suction cups and are suitable for continuous measurement.
Simultaneous display of pH, salinity, and temperature
Configurable high and low alarms for each parameter
Acoustic signal when an alarm is triggered
Automatic temperature compensation
pH calibration at 1 or 2 points
Conductivity calibration at 1 point
Easy installation with adhesive or screw mounting
Probes suitable for continuous measurement in marine aquariums
The probes attach using suction cups with clips and can be positioned at the back of the aquarium. Each probe has a 200 cm cable allowing the monitor installation to be remote.
The system can be calibrated at one or two points for pH (pH 7.01 and 10.01 buffers) and at one point for conductivity at 35.00 ppt. Regular calibration is recommended to maintain measurement accuracy.
