Hanna Instruments

Hanna Instruments was founded in 1978 to design, manufacture and supply a range of enviromental instrumentation. Today, Hanna has offices in 27 countries and manufacturing operations in Europe, America, Africa and the Far East.

Only a few years ago, the measurement of pH and conductivity could be performed by complicated apparatus and trained laboratory technicians. The two methods of measuring these parameters were on opposite ends of the spectrum. At one end, you had the traditional pH litmus paper and kits with low resolution. The other method required training and complicated equipment to perform the analysis. The latter method had extremely high resolution, but could not be performed by everyone. Hanna Instruments introduced the pHep® in 1986. This pocket-sized meter literally replaced pH litmus paper for millions of users worldwide. The powerful electronics provided the operators with unparalleled accuracy, great repeatability, long battery life, and above all, an LCD where measurements could be read easily. Hanna Instruments knew that this was the answer to pH measurement problems! Since the advent of pHep®, Hanna has not only improved the pHep® family by adding waterproof models, but has expanded the line of Pocket Meters to cover areas such as conductivity, relative humidity and salinity. Hanna's commitment to provide innovative, easy-to-use instruments continues with the introduction of testers featuring new ergonomic, and much more rugged casings, as well as larger LCDs for easier viewing from any angle. Add to these the precision of custom microprocessors and you have convenience and accuracy, in pocket size instrumentation.
