The HI5321 is an advanced research grade benchtop EC/TDS/Salinity/Resistivity meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity

The HI98192 is supplied with the HI763133 four-ring conductivity probe with a built-in temperature sensor. This technology allows for accurate readings that cover a complete range with a single sensor. The four ring technology also eliminates the polarization effect that is common with standard two pole versions. The HI763133 conductivity probe connects to the meter with a unique quick connect waterproof DIN connector allowing for a secure attachment without a threaded connection that is also easy to remove.

For the measurement of DO, the HI98193 is supplied with the HI764073 polarographic dissolved oxygen probe. This probe uses preformed PTFE membrane caps that are field replaceable. The probe connects to the meter with a unique quick connect waterproof DIN connector allowing for a secure attachment without a threaded connect that is also easy to remove.

HI83308 is a compact, multiparameter photometer for use in water conditioning applications. The meter is one of the most advanced photometers available with a innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.

HI83399 is a compact, multiparameter photometer for measuring key water and wastewater quality parameters. The meter is one of the most advanced photometers available with a innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette.

HI7032M is a premium quality TDS calibration solution that is prepared against a NIST traceable potassium chloride solution.

Replacing a pH sensor on one of Hanna's compatible testers is both 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. Replacement takes a few seconds and does not have any delicate pins that could break.

For the measurement of pH the HI98191 comes with a HI72911B titanium body pH electrode with a built-in temperature sensor for automatic temperature compensated readings. The titanium body is chemically resistant to aggressive chemicals and is virtually unbreakable.

Bring the performance of a benchtop pH meter with you when you use the HI98190 handheld pH meter.

Pretreatment oxidizing solution, 230 mL

Hanna's portable photometers boast an excellent value due to their comprehensive range of features and affordability.

The HI98121 is a reliable, waterproof tester that ensures quick and easy measurements of both pH and ORP. This accurate pH and ORP tester features 0.01 pH resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device. No more switching between meters for your routine measurements.
