Hanna HI98319U Marine Salinity Tester

Description

Precision Engineering for Marine Salinity Measurement

The Hanna HI98319U Marine Salinity Tester is designed to deliver absolute simplicity and reliability in salinity testing for both natural and artificial seawater. This advanced handheld instrument uses high-accuracy conductivity (EC) measurement to determine salinity, with readings displayed on a multi-level LCD within seconds of dipping the probe into the sample. Capable of providing results in parts per thousand (ppt), Practical Salinity Units (PSU), or Specific Gravity (S.G.), it offers measurement versatility to meet global scientific, aquarium, and industry needs. Supplied with all necessary calibration solutions and a factory-installed battery, the tester is ready for immediate use straight out of the box. Its precision is solidified by the International Oceanographic Tables methodology, ensuring that readings are trustworthy and consistent across any application.

Exclusive Applications for Professional and Hobbyist Use

The HI98319U’s scope of application extends broadly across marine aquaculture, reef aquarium management, oceanographic research, industrial marine process control, and marine environmental field surveys. Hobbyist aquarium keepers value the tester for ensuring their seawater tanks maintain optimal salinity conditions essential for fish and coral health. Industrial users apply the device in marine water processing plants to maintain correct salinity levels for operational efficiency. Scientists utilize it in field surveys to accurately monitor natural seawater salinity fluctuations in diverse environmental conditions, while aquaculture farms rely on it for maintaining healthy salinity levels in breeding enclosures. Portable, durable, and precise, this tester has become a preferred tool where reliable marine salinity measurement is critical.

Advanced Features Deliver Accurate and Stable Readings

To guarantee precise measurements, the HI98319U incorporates an on-screen stability indicator, alerting users when readings are fully stabilized. The selectable auto-off function extends battery life by shutting off the device after a predefined period of inactivity, preventing unnecessary energy consumption. The dual-button interface simplifies calibration and measurement operations, making it accessible to novices yet powerful enough for professionals. By combining automatic temperature compensation between 5 and 50 °C, the instrument ensures salinity readings remain uncompromised in the face of sudden temperature changes—a particularly valuable asset in open field marine measurements or fluctuating indoor environments.

Durable, Compact, and Optimized for Portability

The HI98319U’s 160 x 40 x 17 mm compact housing is waterproof, dustproof, and impact-resistant, offering complete IP-rated environmental protection. Its graphite sensors outperform traditional stainless steel sensors, reducing polarization effects and eliminating oxidation risks for consistent measurements even in challenging water chemistry. The protective carrying case shields the tester from drops or environmental hazards when not in use, while the ergonomic design sits comfortably in your hand for ease of operation. Despite its rugged construction, the tester remains lightweight, making it the ultimate on-the-go marine salinity measurement device.

Simplified Calibration Ensures Long-Term Measurement Accuracy

Calibration is streamlined with the HI98319U’s automatic, single-point procedure at 35.00 ppt, providing users the fastest route to assurance in measurement accuracy. For extended reliability, Hanna includes fresh single-use sachet solutions in both 35.00 ppt and 5.00 ppt standards—ensuring each calibration uses uncontaminated, correctly prepared buffers. Whether in a laboratory or at a coastal site, accurate calibration is essential for repeatable results, and this instrument makes that process intuitive and quick. The device’s calibration memory remains stable over time, supporting prolonged operational consistency in the most demanding marine testing tasks.

Long Battery Life with Intuitive Alerts

Powered by a CR2032 3V Li-Ion battery delivering up to 100 hours of continuous use, the HI98319U is optimized for extended field and laboratory operation without frequent battery changes. A blinking battery icon alerts the user when the charge drops below 10% so that replacements can be prepared before the battery dies. Battery replacement is simple—requiring only a quick counterclockwise twist of the sealed compartment cover. Designed for cost-efficiency and minimal downtime, this battery management system guarantees that your salinity testing is never interrupted during crucial measurements in marine fieldwork or controlled environments.
