"Hanna"

This chemical test kit that uses the DPD method to measure total chlorine. The test kit is supplied complete with all of the reagents and equipment necessary to perform approximately 50 tests.

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 laboratory benchtop dissolved oxygen meter delivers precision while offering simplicity and versatility in a sleek design. Use your multiparameter meter as a portable, benchtop meter, or mount it on the wall to save space.

Slim, versatile meter for accurate EC, TDS, and salinity readings in classrooms or labs.

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.

This wireless field pH meter has a durable PEI body and spherical sensing bulb. All readings are transmitted directly to your Apple or Android device.

Provides a simple, accurate and cost-effective way to measure fluoride.

This multiparameter meter is a waterproof portable logging multiparameter meter. The microprocessor based multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, turbidity, and temperature. The complete system is simple to setup and easy to use.

This is a high quality, bicomponent zero oxygen solution made from reagent grade chemicals. Hanna dissolved oxygen solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution.

Rugged, field-ready meter for multi-parameter water quality testing with GPS logging.

This pH electrode is a plastic body, double junction, gel filled pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design.

The Free and Total Chlorine 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. This meter measures free and total chlorine in water samples from 0.00 - 5.00 mg/L (ppm).

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.

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.

Versatile digital meter for pH, conductivity, and dissolved oxygen measurement in one device.

Single-point pH and conductivity calibration solution for field and lab use.
