Marine Monitor pH, Marine Salinity, and Temperature – HI981520

Marine Line

The system can be calibrated at one or two points for pH and at one point for conductivity. Seawater salinity is expressed in either parts per thousand (ppt), Practical Salinity Units (PSU), or Specific Gravity (S.G.).

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.

Estimated delivery: 8 - 9 September

Features

A high/low alarm can be configured for each parameter and the results are displayed on a large, easy to read LCD.

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 PEI 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.

Two Alarm operating modes (High/Low Value) for each supported parameter

High/Low Alarm generated when measured value exceeds or drops below configured parameter High/Low Value

Acoustic signal generated each time an alarm is triggered

All readings are compensated for variations in temperature

Temperature is displayed in ℃ or ℉ along with pH and EC readings

The EC probe contains an integral temperature sensor that simplifies installation

Easy to read LCD display

Conductivity (EC) Controller (0.0 - 199.9 µS/cm) - BL983320-1 | 115/230VAC

692 AED
The BL983320 is a compact, panel mounted, process controller for measuring electrolytic conductivity (EC) of a process stream that is within the 0.0 to 199.9 µS/cm range. The device features a large LCD with protective cover. Users may choose from automatic or manual dosing modes. When in automatic mode the dry contact relay is activated when a reading is above the set point. The relay can be used to activate a solenoid that switches from one DI (deionized) tank to another or to open a valve that will allow lower EC water to flow into a tank being monitored in order to lower its EC. The BL983320 can also be used to monitor the quality of water produced from ion exchange, reverse osmosis (RO) or distillation. Multicolor LED Indicator LED changes color based on status. Fire Retardant Casing For additional safety the controllers outer case is made of fire resistant plastic. Splash Resistant Cover A clear plastic cover protects the face panel from dirt and liquids.
