SONDELTOX are 4-20mA detectors using electrochemical sensors for the detection of toxic
gases & O2. They are compatible with EUROSONDELCO and SIEMENS CC62P (using interface)
and with any other system provided of 4-20mA standard input.
Sondeltox for oxygen provided of backlit LCD display is available.
Available for these gases; Carbon monoxide (CO), Nitrogen dioxide (NO2), Sulphur dioxide
(SO2), Nitrogen monoxide (NO), Clorhydric acid (HCl), Hydrogen sulphide (H2S), Chlorine (CL2),
Oxygen (O2).

GUARANTEE
SONDELTOX is guaranteed against any manufacturing defect for 1 year
from the date of purchase. The guarantee covers the total repair of the
equipment and will only be valid if the equipment has been installed
by a competent person and following the specifications in this manual.
Negligent use or installation will exempt DURAN ELECTRONICA from its
responsibilities for damage caused to property and/or people and from the
fulfilment of the terms of this guarantee.
The guarantee does not cover:
- Installations, periodical checks and maintenance.
- Repairs caused by improper handling, inappropriate use, negligence,
overload, insufficient power supply or neglecting the equipment, voltage
shorts, defective installations and other external causes.
- Repairs or adjustments carried out by personnel not authorised by
DURAN ELECTRÓNICA.
- The equipment transport costs.
DURAN ELECTRÓNICA reserves the right to carry out improvements or to
include modifications in this manual without prior notice.
For SONDELTOX detectors zeroing –except for SONDELTOX O2 - please
proceed as follows:
1- Cover the detector during 15 min.
2.-Place a multimeter at the scale of 200mV, in parallel, with the yellow
and green cable (fig 1).
3- Adjust through the ZERO potentiometer of the detector circuit until a
reading of 40mV (4mA) is reached.
4- Remove the detector plug. With the plug provided and keep it for future
testings.
For SONDELTOX O2 zeroing, adjust the potentiometer until obtaining a
measurement of 178mV, equivalent to 20.9% of O2, in a wide and well
ventilated room.
The detectors recalibration with gas must be carried out at our laboratories.
SONDELTOX has been tested with several commonly cross-interferring gases and the results are expressed in the table below (in ppm):
Use 2 x 1 mm2shield cable for power supply.
GREEN Cable:
Zeroing (multimeter positive borne)
YELLOW Cable:
Zeroing (multimeter negative borne)
BLACK Cable:
Negative of power supply. 4-20mA Output.
RED Cable:
Positive of power supply. 4-20mA Output.
SONDELTOX CO is provided with a filter to minimize H2S influence, SO2and other interferring gases.
