- Two operating modes (High Value/Low Value) for each supported parameter
- High/Low default alarm system generated during measurement when measured values exceed or drop below configured parameter high/low value
- Acoustic signal generated each time an alarm is triggered
- Automatic Temperature Compensation
- All readings are compensated for variations in temperature
- Temperature is displayed in degrees Celsius and degrees Fahrenheit along with pH or EC reading
- The EC probe contains an integral temperature sensor that simplifies installations
- Easy to read LCD display
Testing and monitoring salinity in saltwater aquariums is an ongoing task. The HI981520 is an easy to use vertical mount unit that continuously monitors and displays conductivity and pH. Each parameter can be configured for High/Low operating mode and the results are displayed on a large, easy to read LCD. The system can be calibrated at one of two points for pH and at one point for conductivity.
The attached two-electrode conductivity probe features a built-in temperature sensor for rapid, high accuracy temperature readings.
The Hanna HI1286 pH double junction. gel-filled pH electrode features a PEWI resin body that is easy to clean and resistant to many aggressive chemicals. Additionally, the double junction design is less susceptible to clogging for fast and stable readings.
The probes can be installed/immersed directly in a tank or aquarium (with supplied suction cups) and are suited for continuous measurement of conductivity and associated parameters required in applications such as seawater, saltwater aquariums, or aquaculture. Each probe features a 2m (6.6') cable length for extended distances between monitor and sample.
Seawater salinity is expressed in either parts per thousand (ppt), Practical Salinity Units (PSU), or Specific Gravity (S.G.).
