"Hanna"

NIST traceable and contained in portable single-use sachets.

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.

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

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.

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.

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

Compact, durable variable speed magnetic stirrer is available with plastic or stainless steel top cover.

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

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.

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.

This pH tester is an easy-to-use pH water tester that makes monitoring water quality simple. This accurate pH tester features 0.1 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device.

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

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.
