Hanna Milestones
Hanna is Technology and Innovation
For over thirty-five years, Hanna has prided itself in being a world leader
in innovation of analytical instrumentation. Headed by our team at
the home office, Hanna’s research and development department
constantly challenge themselves to invent newtesting techniques and
to advance existing technology. The minds at Hanna work to achieve
the common goal of simplifying analytical testing through improving
instrumentation, sensor development, reagents and chemicals.
1978
Hanna Opens in Italy
Hanna was founded in Limena, Italy. Limena is a province of Padua
(AKA Padova) and is located in Northern Italy. It is approximately 40
km west of Venice. Padua is well known for the University of Padua.
Many great scholars of our time have spent time at the university. Most
notable scholars include Galileo Galilei and Nicolaus Copernicus.
1980
World’s first single-probe portable
conductivity meter
The HI8033 is a four pole conductivity portable meter. Having a four
pole design allowed the meter to measure a variety of different
solutions with different conductivity values. The same meter can be
used to measure both deionized water and fertilizer solution.
1982
World’s first pH controlled chemical
dosing pump
The DP7916 combined a pH meter with a chemical dosing pump in
order to maintain a desired set point of a process applications. The
BL7916 is the second-generation design and is still widely used by
many customers including plating, wastewater treatment, water
treatment and swimming pools.
1984
World’s first microprocessor-based
hand held pH meter
The HI8424 was the first portable microprocessor pH meter. The
microprocessor allowed for automatic calibration as compared to
manual calibration with trimmers or potentiometers. The calibration
information was stored in the meter even when it was powered off.
1985
World’s first pH electrode with
built-in temperature sensor
The HI8414 pH meter was the first meter to use a pH electrode
(HI1213S) with a built in temperature sensor. The temperature sensor
allowed for the automatic correction for changes in pHwith changes in
temperature as calculated by the Nernst equation. This advancement
is now commonplace in the industry.
