Hanna HI981520-01 Marine Monitor pH/Salinity/Temperature

Description

Large Vertical Mount Display for Continuous Measurement

The Hanna HI981520‑01 Marine Monitor is an advanced vertical mount monitoring solution developed specifically for precise and continuous measurement of pH, marine salinity, and temperature in saltwater environments. Designed for both residential and commercial use, this system is perfectly suited for at‑home reef tanks, public aquariums, saltwater mixing stations, and marine aquaculture facilities. The monitor features an oversized LCD display that presents real‑time readings for pH in a range from 0.0 to 14.0, salinity in practical units (ppt, PSU, or Specific Gravity), and temperature in °C or °F. The device incorporates a robust IP65‑rated casing for water resistance, making it dependable in humid marine conditions. Large numerical digits and intuitive units are easily readable from a distance, enabling instant verification of water conditions. By maintaining stable environmental parameters, the HI981520 ensures optimal marine life health and ecosystem balance, reducing risks associated with parameter deviation. Every detail of this instrument—from construction materials to calibration functions—was engineered to meet the demands of saltwater professionals and enthusiasts who require uncompromising accuracy.

Integrated Alarms with Visual and Audible Warnings

The HI981520‑01’s alarm system provides two distinct operating modes—high and low—that can be individually configured for each measured parameter. This allows tailored control over the permissible range for pH, salinity, and temperature, which is vital for sensitive marine organisms. Once a reading exceeds or falls below the user‑defined threshold, the device immediately triggers visual warning messages on its large LCD and initiates an audible alarm that can be disabled or enabled according to preference. An alarm state is distinctly indicated by a red backlight display, instantly catching the eye, even in low‑light aquarium settings. This rapid feedback enables corrective action before critical water chemistry deviations can harm aquatic life or disrupt biological filtration stability. The alarm system is engineered specifically for marine conditions where deviations in salinity due to evaporation, or pH fluctuations caused by biological activity, can occur rapidly and unpredictably. Such proactive monitoring ensures a safer environment for coral reefs, invertebrates, and fish species—ultimately saving time, resources, and protecting valuable marine specimens.

High‑Precision Probes with Robust Construction Materials

At the heart of the HI981520‑01’s accuracy are its supplied probes: the HI1286 pH electrode and a fixed two‑electrode conductivity probe with integrated temperature sensing. The HI1286 pH electrode utilizes a PEI resin body—a durable, chemical‑resistant polymer—combined with a porous PTFE junction, offering resistance to fouling and blockage even in heavily stocked aquariums. Its double junction silver‑free electrolyte design minimizes contamination risks, delivering faster and more stable readings in challenging saltwater conditions. The conductivity probe employs dual graphite electrodes for accurate salinity measurement while its tip‑mounted temperature sensor ensures automatic temperature compensation (ATC) for all readings. Both probes feature extended 2 m (6.6 ft) cable lengths, maintaining flexibility in placement and separation between the monitor and water sample. This professional‑grade probe set ensures that salinity, temperature, and pH readings remain reliable over extended operational periods. Their design also reduces maintenance requirements, contributing to long‑term operational efficiency in marine facilities or hobbyist environments.

Flexible Installation for Saltwater Monitoring Applications

Installation versatility is a major advantage of the Hanna HI981520‑01. Probes can be securely affixed inside aquarium tanks using supplied suction cups with clips, enabling continuous in‑tank monitoring without interference to aquatic life or decor. The monitor itself can be mounted onto the aquarium’s exterior vertical wall using screws or the included self‑adhesive fastener strips, ensuring stable positioning for easy viewing and control access. This flexibility allows integration into reef tank cabinetry, public aquarium exhibition areas, or commercial aquaculture testing stations without permanent modification. The supplied hardware ensures straightforward positioning even for novice users. In professional applications such as coral propagation systems or fish breeding facilities, this ability to mount probes in various configurations supports monitoring multiple tanks or zones simultaneously. With its compact size—125 mm x 185 mm x 38 mm—and lightweight 300 g construction, the HI981520‑01 can be incorporated into diverse marine setups without occupying excessive space or requiring complex support structures.

Advanced Calibration Capabilities for Accurate Readings

The Hanna HI981520‑01 offers comprehensive calibration capabilities to ensure measurement precision. pH calibration can be performed manually or automatically through a two‑point process using standard buffer solutions (pH 7.01 and pH 10.01). This allows fine adjustment of the pH probe for maximum accuracy across its measurable range. Salinity calibration is similarly streamlined, featuring a single‑point automatic calibration using a 35.00 ppt standard solution—an industry benchmark for seawater. Temperature calibration is automatic and spans 5 to 50°C (41 to 122°F), ensuring reliable compensation across typical marine environmental ranges. After calibration, on‑screen icons CAL, ATC, and EC confirm operational status. Proper calibration is critical in marine husbandry where even small deviations in pH or salinity can lead to cascading effects on biological systems. This instrument’s straightforward procedure ensures that both beginners and professionals can maintain the highest level of analytical reliability without prolonged downtime or technical complexity.

Applications Across Diverse Marine Environments Globally

The HI981520‑01 Marine Monitor’s capabilities make it an asset in a broad range of marine applications. In home reef aquariums, it provides peace of mind by supplying continuous, accurate readings, protecting delicate coral and fish by catching parameter changes before damage occurs. In public aquariums, its large display allows staff and visitors alike to observe environmental conditions, enhancing educational engagement while maintaining operational safety. In saltwater mixing stations, the monitor ensures that fresh batches of seawater matches desired salinity before introduction into living systems. In marine aquaculture facilities, it supports the health of commercially valuable species by maintaining strict control over environmental chemistry. Available worldwide through tpt24.com, this product is delivered with a guarantee of authenticity and quality, regardless of destination country, ensuring that operators everywhere—from small home setups to large‑scale facilities—can rely on accurate, stable monitoring backed by trusted supply.

Durable Construction and Environmental Resistance Features

Marine environments present unique mechanical and chemical challenges, including constant exposure to salt, high humidity, and variable temperatures. The HI981520‑01 combats these challenges with an IP65 ingress‑protected casing that shields internal electronics from splashes and condensation. Its operational environment tolerance spans 0–50°C (32–122°F) with up to 95% RH non‑condensing, making it suitable for installation near open tanks or within humid grow rooms. The use of corrosion‑resistant materials in the probes extends functional lifespan while reducing maintenance intervention frequency. The supplied power source—a 12 VDC adapter compatible with 115–230 VAC mains—ensures stable continuous operation across global electrical standards. The compact design coupled with advanced sealing and protective materials make this device reliable in both commercial facilities and residential spaces, offering long‑term service without performance degradation even under demanding marine conditions.
