Memosens technology has digitized measurements for over 20 years.
Memosens has revolutionized pH measurement: For the first time, the root causes of measurement errors were addressed directly, rather than merely treating their symptoms.
It all started in 2004 when the first sensors were presented at the INTERKAMA, now known as ACHEMA, in Frankfurt.
The patent was published later that year. It claimed a potentiometric sensor, comprising:
- pH electrode for recording pH value
- An inductive interface for outputting a signal
- A digital data memory permanently connected to the sensor
- A potentiometric sensor as per Claim 1 further comprising a microprocessor for controlling the data memory and/or for controlling the interface for communication with the higher order unit.
- A potentiometric sensor as per one of the Claims 1 to 2, whereby the data memory is switched in such a way that it can be controlled by the higher-order unit.
In 2005, the measuring point was able for the first time to display and process all Memosens data with the introduction of the Liquiline CM42 two-wire transmitter.
In the following years, glass-free pH ISFET sensors and Memosens sensors for dissolved oxygen, conductivity and chlorine were launched.
In 2009, standardization was pushed by strategic partnerships with competitors. The Memosens protocol was opened up to further producers of liquid analytical products, offering our customers the opportunity of second sourcing and establishing Memosens as a de-facto standard.
In 2010, the Liquiline CM442 transmitter was introduced offering hot plug-and-play and simple change of parameters with Memosens sensors.
In the following years, more and more fixed-cable sensors with Memosens technology were introduced for turbidity, nitrate, ammonium and many more parameters.
2014 was the start of Liquiline System, a new generation of colorimetric analyzers, enabling the connection of Memosens sensors and offering the functionality of complete, multi-parameter measuring stations.
The year 2021 saw the launch of Memosens 2.0. The new sensor generation is able to save even more data, offering the perfect basis for predictive maintenance and IIoT services.
Today, Memosens sensors cover all relevant parameters of liquid analysis providing optimum product yield and process quality.
