Convenient and User-Friendly
Equipped with a simple user interface. Results are displayed on a large, easy to read LCD screen. Users can choose their desired units for salinity (ppt, PSU, Specific Gravity (S.G.) and temperature (C° or F°).
Vertical Mount Unit
Monitor can be affixed to the aquarium tank wall.
Suction Cup with Clips
The probes can be installed/immersed directly in an aquarium tank (with supplied suction cups) and are designed to continuously monitor pH, salinity, and temperature levels.
Two Alarm Operating Modes
A high/low value can be configured for each parameter.
High/Low Alarm
Users can be alerted when a measured reading exceeds or drops below the set high/low value.
Visual and Audible Notifications
Displays warning messages and a sound signal is generated when an alarm is triggered. This notifies you when readings are outside of supported ranges.
pH Electrode (HI1286)
Supplied with a pH double junction electrode with a PEI resin body. This makes the pH electrode resistant to many aggressive chemicals. It is also easy to clean and less susceptible to clogging for fast and stable pH readings.
Fixed EC & Temperature Probe
Attached to the monitor, this two-electrode conductivity probe features a built-in temperature sensor at the tip of the EC sensor. This allows for rapid and accurate salinity and temperature readings.
Extended Cable Length
Each probe features a 2 m (6.6’) cable length for extended distances between the monitor and the saltwater sample.
Suction Cup Attachment & Mounting Features
Easily attaches to aquarium's exterior to enable regular monitoring. The probes are secured with suction cups to the back of an aquarium (tank) and are suited for continuous measurement of conductivity and associated parameters required in applications such as seawater, saltwater aquariums, or aquaculture. A monitor mount component contains pre-cut strips, featuring a strong adhesive that adheres to most smooth surfaces (e.g., glass, metal, tile).
