Introduce withour new product
22.6.2011: New product - MPH71
We would like to inform you about our new product - MPH71 - Advanced potentiometric converter.
It is suitable for all our electrodes. These type integrates mV-meter, ionmeter and
pH meter with temperature compensation. It also enables communication with PC or PLC via RS232
and current loop. Both outputs are galvanically isolated from measuring part to prevent influence
of connected devices.
28.2.2011: New type of pH electrode in pricelist
For big interest from our customers we decided to add new pH electrode to
pricelist - 01-29LR. This electrode is especially suitable for measurement
in low temperatures (it has low electrical resistance). This is important because
resistivity of each pH electrode is strongly dependent on temperature. If the electrode
has resistance 100 Mohm at laboratory temperature, at zero it will be about 800Mohm.
If there is longer cable needed (more than one meter), the measurement will
be noisy and report bad values because of nonlinearity of input.
1.10.2008: 40 years of ISE
This year is 40th anniversary from beginning of the production
of ion selective electrodes in our firm Monokrystaly. First notice about
development of ISE in our firm was presented on meeting in Hungary in 1968
year (Veselý J., Jindra J.: IMEKO – Symposium on electrochemical sensors,
p. 69, 1968, Veszprem, Hungary). First production of ion selective electrodes
with plastic membrane in our firm was started in 1974 year (Semler M.,
Adametzová H.: J. Electroanal. Chem. Interfac. Electrochem., vol. 56, p.
155, 1974). First electrodes with membrane with mixed innorganic compounds
were produced in 1977 year (Semler M., Mánek B.: Conference on ion selective
electrodes, p. 529, 1977 Budapest, Hungary). Test of the first our electrodes
carried out by Šůcha, Suchánek, Urner and coworkers from Institute of chemical
technology in Prague, by Kotrlý, Vytřas and coworkers from University of
Pardubice and by Šenkýř and coworkers from Masaryk University, Brno. Today
our firm produce 20 types of ion selective electrodes, including gas sensing
electrodes, many types of
pH glass electrodes,
redox electrodes,
reference electrodes and
pH-meters.
