Apera Instruments YD300 Portable Water Hardness Meter Kit with 601-S Combination Electrode
Product Description
The Apera Instruments YD300 is a portable water hardness meter designed for accurate and rapid measurement of calcium (Ca2+) and magnesium (Mg2+) ion concentrations, essential in biotechnology, environmental monitoring, and clinical diagnostics involving water quality analysis. Utilizing a patented 601-S 3-in-1 water hardness combination electrode, this device integrates a measuring electrode, reference electrode, and temperature electrode to deliver precise results comparable to the traditional EDTA titration method but with enhanced convenience and no chemical reagents required.
Key features include:
- Electrode method accuracy equivalent to EDTA volumetric titration, eliminating the need for probe stirring or reagent addition, enabling direct ion concentration measurement akin to pH testing.
- Intelligent chip design ensuring stable potential generation, fast response times, and ease of operation.
- Automatic Temperature Compensation (ATC) and automatic calibration enhance measurement reliability across variable environmental conditions.
- Storage capability for up to 99 groups of data facilitating longitudinal water quality monitoring.
- Ability to switch between eight common units of water hardness measurement, including mmol/L, mg/L (CaCO3), mg/L (CaO), mmol/L (Boiler), mg/L (Ca), and various national hardness degrees (˚fH, ˚dH, ˚eH).
- Portable IP57 waterproof design housed in a rugged carrying case, suitable for field testing and laboratory use in bioprocessing, aquaculture, and cooling tower water analysis.
- Comprehensive kit includes the 601-S combination electrode, calibration solutions (B1, B2, B3), calibration bottles, activation solution, test cup and pedestal, batteries, and user manual.
Applications encompass drinking water quality assurance, wastewater treatment monitoring, cooling system maintenance, and bioprocess water hardness evaluation, making the YD300 a critical instrument widely adopted in molecular diagnostics workflows and biopharmaceutical production pipelines where water quality is vital.
The device is backed by a two-year warranty on the instrument and six months warranty on the electrode, ensuring reliability and professional performance in demanding laboratory and field environments.
