EC PROBE

Controller and conductivity sensor
ECTESTOC-3D-P DOSATRON SONDE 1R26-CTM-COS probe

SPECIFICATIONS

Specially designed for the qualitative control of circulating fluids.
A 3-digit LED display provides a direct reading of the metering and calibration
values.
A red light indicator makes it possible to check the internal battery charging
level.
A probe featuring stainless steel electrodes provides a virtually unlimited
service life under normal operating conditions. The temperature compensation
is carried out using a NTC thermistor probe.

PUTTING INTO ORDER
Both the EC reader and the probe
are supplied already fitted.
Open the EC reader housing
(removing the 4 screws at the front)
and remove the battery protective
tab.
(Please pay attention to the
polarity symbols + and -)
Probe cable gland
Close back the housing and the
reader will be operational.
OPERATION
Measurement shall only be accurate if the probe is in direct contact with the
fluid.When the probe is in contact with the air, the measured value is close
to 0.0 mS.
EC reading is
displayed in mS/cm
Red warning light
on = replace the
2 batteries
CALIBRATION TO BE CARRIED OUT ONCE A YEAR
The calibration and correct operation check of the EC reader is done using
a 1.413 mS conductivity reference solution. Place the probe in the reference
solution (not supplied).
