Digital Salinity Meter, Platinum Electrode & Concave Surface for Lab-Grade Accuracy, Auto-Measured Salt Content Tester, Rapid Test for Aquarium/Saltwater/Salty Food, Range: 50ppt/1.000〜1.045

Description

Product Overview

The LOHAND LH‑SA50 Digital Salinity Meter is engineered for laboratory‑grade precision while remaining user‑friendly for everyday applications. Featuring a platinum‑coated concave electrode, the device minimizes interference from surface tension and provides stable, repeatable readings across a wide salinity range of 0‑10% (0‑100ppt) and specific gravity 1.000‑1.045. The large, high‑contrast color LCD displays salinity, specific gravity, temperature, and battery status simultaneously, allowing operators to verify multiple parameters at a glance. Powered by two AAA batteries included in the package, the meter offers up to 500 measurements per charge, making it suitable for field work, aquarium maintenance, food processing, and scientific research. The compact housing, measuring just 8.66 x 4.41 x 1.54 inches and weighing 6.74 ounces, fits comfortably in a lab bench drawer or a portable kit. Robust ABS plastic and sealed internal circuitry protect the instrument from splashes and accidental drops, extending its service life well beyond typical consumer‑grade meters.

Usage

Designed for versatility, the LH‑SA50 excels in a variety of environments. In home aquariums, hobbyists can quickly test water salinity before adding new marine species, ensuring optimal osmotic balance and preventing stress‑induced mortality. Commercial fish farms rely on the meter to monitor brine concentrations in recirculating systems, helping maintain consistent growth rates and disease resistance. Culinary professionals use the device to verify salt levels in cured meats, brined vegetables, and seafood preparations, guaranteeing product consistency and compliance with regulatory standards. The instrument also serves educational institutions, where students perform experiments on solution conductivity and learn the relationship between salinity and specific gravity. Its auto‑measure function simplifies data collection: simply immerse the electrode, press the measurement button, and the meter automatically compensates for temperature, delivering a calibrated reading within seconds. The included pipettes and cleaning cloth facilitate easy sample handling and electrode maintenance, reducing cross‑contamination risk.

Why Choose Us

LOHAND combines decades of experience in analytical instrumentation with a commitment to quality control and customer satisfaction. Each LH‑SA50 unit undergoes a rigorous calibration process against certified reference standards before leaving the factory, ensuring that every measurement meets the advertised accuracy of ±0.01% salinity and ±0.001 specific gravity. The concave electrode design, patented by LOHAND, reduces the impact of surface films and bubbles, a common source of error in traditional flat‑plate probes. Our after‑sales support includes a one‑year limited warranty covering manufacturing defects, as well as lifetime technical assistance from a dedicated engineering team. Users receive a comprehensive user manual with step‑by‑step instructions, troubleshooting tips, and recommended maintenance schedules.

FAQ

How often should I calibrate the meter?

For routine aquarium or food‑service use, calibrate the meter every 30 days using a standard solution of known salinity. In a laboratory setting, perform calibration before each batch of measurements or whenever the device experiences a temperature shift greater than 5 °C.

Can the meter measure temperature independently?

Yes, the LH‑SA50 includes an integrated temperature sensor that displays the ambient temperature of the sample. This temperature reading is automatically used to correct salinity and specific gravity values, eliminating the need for a separate thermometer.

Is the device safe for use with corrosive solutions?

The platinum‑coated electrode is highly resistant to corrosion from saline and mildly acidic solutions. However, for highly aggressive chemicals such as strong acids or bases, it is recommended to rinse the electrode thoroughly with distilled water after each use to preserve longevity.

What batteries are required and how long do they last?

The meter operates on two AAA batteries, which are included in the package. Under typical usage—approximately 200 measurements per day—the batteries will last up to six months before replacement is needed.

Can I use the meter for freshwater testing?

While the LH‑SA50 is optimized for saline environments, it can also measure low‑conductivity freshwater samples. The device will display salinity values close to zero, and the temperature reading remains accurate.
