Hanna HI98319 Marine waterproof salinity tester

Hanna HI98319 Marine Waterproof Salinity Tester

The Hanna HI98319 Marine waterproof salinity tester  is a precision-engineered waterproof salinity tester specifically designed for marine aquariums, saltwater systems, and aquaculture applications. It provides accurate, on-the-go measurement of salinity in ppt (g/L), PSU (Practical Salinity Units), and specific gravity (S.G.). With a compact design and advanced compensation features, it ensures dependable results for marine professionals and hobbyists alike.

Features

• 3 Measurement Modes in One Device
  The HI98319 simultaneously displays salinity in ppt, PSU, and specific gravity (S.G.), giving users the flexibility to work with their preferred units. As a result, it’s adaptable to both scientific and practical use cases.

• Dual Range with High Accuracy
  Provides a low range of 0.00 to 10.00 ppt / PSU and a high range up to 70.0 ppt / PSU, covering the full salinity spectrum for marine environments. Moreover, the device automatically adjusts resolution and accuracy depending on the concentration for optimal precision.

• Built-In Temperature Compensation
  Salinity readings are automatically compensated for temperature changes between 5.0 to 50.0°C, delivering accurate results under varying conditions. Consequently, you get consistent data, even in dynamic water environments.

• Scientific-Grade Measurement Methods

  • ppt based on International Oceanographic Tables (1966)

  • PSU based on Standard Methods for Water and Wastewater, 2520 B

  • S.G. based on Standard Methods, 2520 C (Density)
    Therefore, this tester adheres to widely recognized scientific protocols, ensuring reliable and standardized results.

• Simple Calibration Process
  Calibrates automatically at one or two points using Hanna calibration solutions (HI-70023 at 5.00 ppt or HI-70024 at 35.00 ppt). In addition, users can quickly recalibrate in the field without any hassle.

• Compact, Lightweight, and Waterproof
  Weighing just 68 g, the tester is ideal for fieldwork and lab use. With its waterproof body and ergonomic shape, it is both rugged and comfortable to use.

• Energy-Efficient Operation
  Powered by a CR2032 3V lithium-ion battery, the HI98319 offers up to 100 hours of continuous use, making it both convenient and reliable for frequent monitoring.
