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
The Stratos Eco 2405 pH is used for pH/mV, ORP, and temperature
measurement in industry, environment, food processing, and sewage
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 has been designed for application with commercially
available sensors with a nominal zero point at pH 7. 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.

Installation Instructions
CAUTION!
• Installation of the Stratos must be carried out by trained experts in
accordance with this instruction manual and as per applicable local
and national codes.
• Be sure to observe the technical specications and input ratings
during installation.
• Be sure not to notch the conductor when stripping the insulation.
• Before connecting the device to the power supply, make sure that
its voltage lies within the range 20.5 ... 253 V AC/DC.
• All parameters must be set by a system administrator prior to
commissioning.
The terminals are suitable for single wires and exible leads up to
2.5mm2(AWG 14).
