"HANNA INSTRUMENTS"

Direct soil conductivity tester for measuring salinity and nutrient levels without sample preparation.

This chemical test kit for the determination of six parameters commonly monitored for aquaculture testing: alkalinity, carbon dioxide, hardness, dissolved oxygen, pH, and salinity. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna's pH tester, which guarantees greater accuracy and a longer life than traditional litmus paper.

This spare pH sensor makes electrode replacement quick and easy. The spare pH sensor is designed as an easy-fit cartridge that locks into place, featuring two o-rings to maintain a watertight seal. With no pins to line up or that can break, this sensor is ideal for quick replacements.

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.

This titration-based chemical test kit determines the alkalinity concentration in samples within a 0 to 100 mg/L (ppm) CaCO₃ or 0 to 300 mg/L CaCO₃ range.

This chemical test kit measures total hardness as CaCO₃ by titration with EDTA. It includes all of the reagents and equipment necessary to perform approximately 100 tests.

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

This dissolved oxygen meter is a rugged, portable, waterproof dissolved oxygen (DO) meter designed to provide reliable measurements under harsh environmental conditions.

The Environmental Chemical Test kit is a chemical test kit for the determination of six parameters commonly monitored for environmental testing: acidity, alkalinity, carbon dioxide, hardness, dissolved oxygen, and pH. This kit is equipped with all the necessary reagents and equipment to perform over 100 tests for each parameter. pH is obtained with Hanna‘s pHep®, pH electronic tester.

Backpack Lab designed for educators and environmental science students, containing lessons, activities, and test kits that relate to important parameters evaluated in soil quality. 

Use our simple handheld colorimeter to get higher accuracy water testing results. Forget about the struggle of matching your sample to a color chart, our total chlorine colorimeter eliminates the struggle and provides you a digital total chlorine result directly. Our ammonia colorimeter brings you more precise technology than your typical chemical test kit giving you accurate and consistent results.

These reagents are the replacement reagents for the total chlorine checker® HC. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

The replacement reagents for the iron tester sold seperatly. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

Designed to bring simplicity to environmental testing, this pH/EC/TDS Meter is designed specifically for use in manufacturing and environmental testing protocols. The specialized electrode combines 3 sensors in a single rugged probe body featuring a polypropylene body, integrated temperature sensor, and cloth junction.

Checktemp® Digital Thermometer is a great choice for easy operation with clear digits and better accuracy over a wide range. Measure temperature without fear of breakage or condensation. A compact meter with a direct probe, it is ideal for taking quick–fire temperature measurement in semi-solids and liquids.

This is a chemical test kit that measures dissolved oxygen by modified Winkler titration. The HI3810 is supplied complete with all of the reagents and equipment necessary to perform approximately 110 tests.
