Hanna Instruments HI98319 is a salinity tester made specifically for the saltwater aquarium enthusiast and can measure salinity up to 70.00 ppt. The rugged waterproof tester is only 0.7″ thick and extremely ergonomic, fitting comfortably in your hand. The HI98319 keeps things simple with a two-button operation; one for ON/OFF, and the other for calibration. The salinity tester features a large multi-level LCD which displays either PPT, PSU, or specific gravity along with the temperature. Temperature can be set to display in oC or oF. An exposed temperature sensor allows for rapid automatic temperature-compensated measurements. The LCD screen has stability and calibration tag indicators. A battery percent level indicator is displayed at startup to alert the user of the remaining available battery power. Salinity readings are performed by an amperometric graphite probe that resists oxidation, providing better repeatability in measurements. The use of graphite also reduces the polarization effect common with testers that use two stainless steel pins. Calibration is performed by pressing the dedicated calibration button. Once in calibration mode, the probe is placed in a 35.00 ppt calibration standard. When the standard value is recognized and stability is reached, the meter will automatically accept and store the value. Setup options include an adjustable automatic shut-off in which the meter can be set to turn off after 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment. HI98319 waterproof salinity tester provides a simple, accurate, and cost-effective way to determine the salt concentration in saltwater aquariums.
