Safety information –
Be sure to read and observe the following instructions!
The device has been manufactured using state of the art technology
and it complies with applicable safety regulations.
When operating the device, certain conditions may nevertheless lead
to danger for the operator or damage to the device.
CAUTION!
Commissioning must be carried out by trained experts.
Whenever it is likely that protection has been impaired, the device
shall be made inoperative and secured against unintended operation.
The protection is likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended measurements
• after prolonged storage at temperatures above 70°C
• after severe transport stresses
Before recommissioning the device, a professional routine test in
accordance with EN 61010-1 must be performed. This test should be
carried out at the manufacturer’s factory.
CAUTION!
Before commissioning, make sure that the transmitter may be
connected with the other equipment.

Intended Use
Stratos Eco 2405 Cond is used for measurement of electrical
conductivity and temperature in liquids. Fields of application are:
biotechnology, chemical industry, environment, food processing,
water/waste-water treatment.
The sturdy molded enclosure can be xed into a control panel or
mounted on a wall or at a post.
The protective hood provides additional protection against direct
weather exposure and mechanical damage.
The device can be used with all 2- and 4-electrode sensors. It provides
two current outputs (for transmission of measured value and tem-
perature, for example), two contacts, and a universal power supply
24...230VAC/DC, AC: 45 ... 65 Hz.
