Select the measuring mode whose data are going to be printed.
Press PRINT 2 (1.15) and all the data saved in that measuring mode will be printed or
transmitted to the PC.
If you are not using the conductivity meter for a long period of time please make sure
it is disconnected from the net and protected from dust (this way you will avoid accidents
and will extend its working-life).
Security
The conductivity meter must be used by previously qualified staff that knows how the
equipment works thanks to the user manual.
Put the conductivity meter on top of a horizontal, plane and stable table making a free
space at least at 30 cm per side.
Do not put the conductivity meter near any warm supply (burners, blowlamps...), nor
expose it directly to the sun, etc. Avoid vibrations, dust and dry environments.
When you are not using the conductivity meter for a long period of time please make
sure it is unplugged in order to avoid possible accidents.
During operation, dangerous material such as flammable liquids or pathological mate-
rial must be out of the working area.
It is essential to have the equipment switched off and unplugged from the net before
cleaning, checking components or replacing any piece.
Never try to repair the conductivity meter by yourself, since you will lose the warranty
and may provoke damages to the general operating system or the electrical installation,
as well as injuries to the people that usually handle the equipment (burns, hurts...).
Try not to spill any liquid on the control panel, though it is properly insulated. In case
you have any doubts do please immediately unplug the equipment (see Maintenance).
Made under the European regulations for electrical security, electromagnetic compati-
bility and security on machines.

1. APLICACIONES DEL INSTRUMENTO
La conductividad es una medida de la cantidad de iones presentes en una solución y su
determinación constituye un método de referencia en los análisis de calidad de aguas en
multitud de industrias y aplicaciones. Para ello, Nahita le ofrece este conductímetro digi-
tal especialmente diseñado para su uso en laboratorios y que permite la determinación de
la conductividad, sólidos totales disueltos (TDS) y salinidad. El equipo dispone de 6 ran-
gos diferentes de conductividad y 5 de TDS para seleccionar el que ofrezca la mejor reso-
lución y precisión y además puede ser utilizado con células de conductividad de cons-
-1
tante 0.01, 0.1, 1, 5 y 10 cm
. De este modo, el conductímetro Nahita 910/8 constituye un
instrumento adecuado para la mayoría de las aplicaciones ya que permite analizar desde
muestras de muy baja conductividad (agua ultrapura) hasta muestras de elevada con-
ductividad (agua de mar).
