Stratos Evo is a 4-wire analyzer for process analysis applications.
The analyzer comes as basic device for measurement with digital sensors
(Memosens, optical oxygen measurement, inductive conductivity measurement).
All measuring functions are stored in an internal memory. You select a measuring
function to congure the analyzer for a specic measuring task. Additional measur-
ing modules can be connected to allow measurement with analog sensors.
The Model A402B 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 transmis-
sion of measured value and temperature, for example. Four oating relay contacts
are available for free conguration. A PID controller and a time-controlled cleaning
function can be congured. Two parameter sets are provided. You can externally
switch between them via the Control input, for example. The HOLD input allows
setting the HOLD mode from the outside. The analyzer also provides power supply
and allows signal processing for additional transmitters, e.g., for ow monitoring.
You can select one of the following measuring functions:
• pH
• ORP
• Oxygen
• Oxygen, optical
• Conductivity measurement (conductive/inductive)
• Dual conductivity measurement using two analog sensors
• Dual measurement of pH/pH and pH/Oxy using two Memosens sensors
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 for:
• 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)
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
Introduction

Display
Plain-text messages in a large, backlit LC display allow intuitive operation.
You can specify which values are to be displayed in standard measuring mode
(“Main Display”).
Color-coded user interface
The colored display backlighting signals dierent operating states (e.g., alarm: red,
HOLD mode: orange).
Diagnostics functions
Diagnostics functions are provided by the “Sensocheck“ automatic monitoring of
glass and reference electrode and the “Sensoface“ function for clear indication of the
sensor condition.
Data logger
The internal logbook (additional function, TAN SW-A002) can handle up to
100entries – up to 200 with AuditTrail (additional function, TAN SW-A003).
2 parameter sets A/B
The device provides two parameter sets which can be switched manually or via a
control input for dierent process adaptations or dierent process conditions.
For an overview of parameter sets (original for copy), refer to the CD or
www.knick.de.
Password protection
Password protection (passcode) for granting access rights during operation can be
congured.
Automatic calibration with Calimatic
You can choose from the most commonly used pH buer solutions.
In addition, you can enter an individual pH buer set.
