"Hanna"

This electrode storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. Properly storing your pH electrode in a solution keeps the glass membrane well hydrated which maintains proper function and provides accurate readings.

The pHep®5 is an advanced, waterproof pH and temperature tester with 0.01 resolution that makes measuring quick and easy. This accurate pH tester features 0.01 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device. No more switching between meters for your routine measurements.

This multiparametrer tester is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off.

Functional and accurate, this meter is capable of testing 12 different water quality parameters using pH, EC, and optical DO sensors. Transfer data to a smart device for review or sharing with the integrated Bluetooth connection and Hanna Lab App.

This chemical test kit measures six parameters common in water quality testing: alkalinity, chloride, hardness, iron, pH, and sulfite. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter, with the exception of iron, which includes reagents for 50 tests. pH is obtained with one of Hanna's pH electronic testers, which guarantees greater accuracy and a longer life than traditional litmus paper.

Gentle cleaning solution designed to remove buildup and maintain electrode accuracy.

This chemical test kit measures chloride by titration with mercuric nitrate. This test kit supplied complete with all of the reagents and equipment necessary to perform approximately 110 tests.

Reliable pH 4 calibration buffer for accurate meter standardization and lab use.

This chemical test kit measures carbon dioxide by titration with sodium hydroxide. It is supplied complete with all of the reagents and equipment necessary to perform approximately 100 tests.

Neutral pH 7 calibration buffer for standardizing pH meters and electrodes.

Sleek, versatile pH and ORP meter designed for laboratory, classroom, or field use.

The Total Hardness Photometer combines accuracy and ease of use in a simple, portable design. The advanced optical system provides lab-quality accuracy while its user-friendly design is easy for any user making it the perfect photometer for your water quality testing needs. The HI97735 meter measures total hardness in water samples up to 750 mg/L (ppm) CaCO₃.

Comprehensive, field-ready system for testing multiple water quality parameters with precision.

This tester is an advanced, waterproof conductivity and TDS (ppm) tester for quick and easy measurements while on the go. This lightweight, waterproof conductivity tester offers accurate conductivity (0 to 3999 µs/cm), TDS (0 to 2000 ppm), and temperature measurements in a single, portable, pocket device. No more switching between meters for your routine measurements.

This general purpose cleaning solution can be used for a variety of applications. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and to prevent any clogging of the junction.
