Introduction
Stratos MS is a 4-wire analyzer for use with Memosens sensors. The Model A405B
allows applications in hazardous-area Zone 2. Current is provided through a
universal power supply 80...230VAC, 45...65Hz / 24...60VDC.
The analyzer provides two 0 (4) .... 20mA current outputs for transmission of
measured value and temperature, for example.
Two oating relay contacts are available for free conguration.
You can select one of the following measuring functions:
• pH
• ORP
• Dissolved oxygen
• Conductivity measurement (conductive/inductive)
Enclosure and mounting possibilities
• The sturdy molded enclosure is rated IP 67/NEMA 4X outdoor.
Material of front unit: PBT, rear unit: PC.
Dimensions: H 148 mm, W 148 mm, D 117 mm.
It is provided with knockouts to allow:
• panel mounting (138 mm x 138 mm cutout to DIN 43700)
• wall mounting (with sealing plugs to seal the enclosure)
• post/pipe mounting (dia. 40 … 60 mm, 30 … 45 mm)
Protective hood (accessory)
The protective hood provides additional protection against direct weather exposure
and mechanical damage (available as accessory).
Connection of sensors, cable glands
For connecting the cables, the enclosure provides
• 3 knockouts for cable glands M20x1.5
• 2 knockouts for NPT 1/2” or rigid metallic conduit
Memosens sensors and connecting cables

14 Memosens Sensors
Start-Up
When a Memosens sensor is connected, the appropriate measuring function
(device type) is automatically loaded.
Changing the Measuring Function
In the “Service”menu you can select another measuring function at any time.
Calibration and Maintenance in the Lab
The “MemoSuite” software allows calibrating Memosens sensors under reproducible
conditions at a PC in the lab. The sensor parameters are registered in a database.
Documenting and archiving meet the demands of FDA CFR 21 Part 11. Detailed
reports can be output as csv export for Excel. MemoSuite is available as accessory
and comes in the versions“Basic” and “Advanced”: www.knick.de.

Operation
Measuring Mode
After the operating voltage has been connected, the analyzer automatically goes to
“Measuring“ mode. To call the measuring mode from another operating mode (e.g.,
Diagnostics, Service): Hold meas key depressed (> 2 s).
Depending on the conguration, you can set various displays as standard display for
the measuring mode (see page20).
Note: By pressing the meas key in measuring mode you can view the displays for
approx. 60 sec.
