1 Safety
This document contains important instructions for the use of the product. Always fol-
low all instructions and operate the product with caution. If you have any questions,
please contact Knick Elektronische Messgeräte GmbH & Co. KG (sometimes hereafter
referred to as “Knick”) using the information provided on the back page of this docu-
ment.
1.1 Intended Use
The SE605H (the “product”) is a coaxial 2-electrode sensor with a measuring range of
0…1000µS/cm. The sensor body and sensing electrodes are made of stainless steel.
The sensor is ideal for use in the hygienic measuring and monitoring of ultrapure water.
The measurement data is output via a suitable industrial transmitter.
The defined operating conditions must be observed when using this product.
➜Specifications, p. 32
Sealing from the process is only ensured if the SE605H sensor is operated with Knick
weld-in sockets. ➜Accessories, p. 28
If weld-in sockets from other manufacturers are used, they must be tested and evalu-
ated by the operating company.
1.2 Personnel Requirements
The operating company shall ensure that any personnel using or otherwise interacting
with the product is adequately trained and has been properly instructed.
The operating company shall comply and cause its personnel to comply with all appli-
cable laws, regulations, codes, ordinances and relevant industry qualification standards
related to product. Failure to comply with the foregoing shall constitute a violation of
operating company’s obligations concerning the product, including but not limited to
an unintended use as described in this document.

1.3 Residual Risks
The product has been developed and manufactured in accordance with generally ac-
cepted safety rules and regulations. The SE605H sensor was subjected to a risk assess-
ment. Nevertheless, not all risks can be sufficiently reduced; the following residual risks
remain:
Environmental Influences
The effects of pressure, moisture, corrosion, chemicals, and ambient temperature can
negatively impact on safe operation of the product.
Observe the following instructions:
• Only operate the SE605H sensor in compliance with the stated operating condi-
tions. ➜Specifications, p. 32
• If using chemically aggressive process media, regularly check the SE605H sensor for
damage.
• Adhering and sticky process media may interfere with measurements. Regularly
remove adherents. As required, recalibrate the SE605H sensor. ➜Cleaning, p. 21
➜Calibration, p. 22
1.4 Hazardous Substances
In certain situations (e.g., sensor replacement), personnel may come into contact with
the following hazardous substances:
• Process medium
• Cleaning medium
This document specifies the personal protective equipment that needs to be used
when carrying out handling instructions.
The operating company is responsible for conducting a hazard assessment.
See the relevant manufacturers’ safety data sheets for hazard and safety instructions on
handling hazardous substances.

1.5 Operation in Hazardous Locations
The SE605H-X is certified for operation in explosive atmospheres.
Observe all applicable local and national codes and standards for the installation of
equipment in explosive atmospheres. For further guidance, consult the following:
• IEC60079-14
• EU directives 2014/34/EU and 1999/92/EC(ATEX)
• NFPA70(NEC)
• ANSI/ISA-RP12.06.01
The electrical and thermal parameters of the sensors must be adhered to.
➜Electrical and Thermal Parameters in Hazardous Locations, p. 7
Memosens Ex sensors are marked by an orange-red ring.
Combined with a model CA/MS‑***X**, model CA/MS‑***X**‑L measuring cable, or a
certified measuring cable that is identical in hardware and function, the sensor may be
connected to a suitable measuring device, as specified in the Certificates BVS 15 ATEX
E141 X and IECEx BVS 15.0114 X.

Special Conditions
• The measuring cable and sensor may only be used within the ambient temperature
range specified for the temperature class.
• The measuring cable, including its connecting head, must be protected from elec-
trostatic charging if it passes through areas of Zone 0 (category 1G).

• The Memosens sensors may not be operated in electrostatically critical process
conditions. Intense vapor or dust flows directly impacting on the connection
system must be avoided.
• Metallic process connection parts must be mounted at the installation site so that
they are electrostatically conductive (<1MΩ).
