Hanna Monitor for saltwater aquariums pH, salinity and temperature

The HI981520 Aquarium Monitor is an easy-to-use monitor that continuously monitors and displays salinity (via electrical conductivity, “EC”) and pH.

The system can be calibrated at one or two points for pH and one point for conductivity. The salinity of the seawater is displayed in either parts per thousand (ppt), practical salinity units (PSU) or specific gravity (SG). A high/low alarm can be configured for each parameter. The measurement results are continuously displayed on a large, easy-to-read LCD.

The permanently connected 2-ring conductivity probe has an integrated temperature sensor for fast, highly accurate temperature measurements. The gel-filled pH electrode HI1286 has a PEI body that is easy to clean and resistant to many aggressive chemicals. In addition, the double diaphragm design is less susceptible to clogging and ensures fast and stable readings. The pH electrode is replaceable.

• Two alarm operating modes (maximum/minimum) for each supported parameter
• High/low alarm (is triggered when the measured value exceeds or falls below the configured maximum/lowest value for the respective parameter)
• acoustic alarm signal
• All measured values ​​are temperature compensated
• The temperature is displayed in °C or °F along with the pH and EC readings
• The EC probe contains an integrated temperature sensor
• Easy-to-read LCD
