The device is available with a white light source or an infrared light source. There are no visible
differences between these versions. Both versions provide the possibility of ultrasonic cleaning.
Every device has a pressure regulator for the incoming flow which reduces pressures up to
14 bar / 203 psi down to 1 bar / 15 psi.
Dehumidification system
The device is equipped with a continuous dehumidification system that works with the help of a
replaceable desiccant pouch in the electronic device. While the system heat is used to warm the
air, a fan inside the device continuously circulates this heated and by the desiccant pouch
dehumidified air around the optical well and the electronic device. This features eliminates the
need for a dry purge line.
The device monitors the replaceable desiccant pouch condition continuously. The lower line of
the display shows the message "DESC" in the event that you have to replace a saturated
desiccant pouch that may cause problems.
Liquid crystal display (LCD)
For a better readability in low light or no light conditions the LCD is backlight. The backlight
always stays on, but the brightness is adjustable.

RS 485 interface
In addition to the Modbus communication the device can operate in two other RS 485 modes:
•Online: the device operates as a small SCADA system (Supervisory Control and Data
Acquisition) with an optional software package (to get this package contact the manufacturer
or your local sales office). This system allows the connection of up to 255 devices which all
have to be an OPTISYS TUR 1050. Furthermore this system offers a direct interface with
common database and spreadsheet software.
•Simple: the device can provide basic communications with the help of simple programs.
Examples for such programs are Hilgraeve hyperterminal (included in most Microsoft
Windows packages) or Visual Basic.
Ultrasonic cleaning
This feature helps to clean the ultrasonic cuvette continuously. The system works by sending an
ultrasonic frequency through spring connections in the upper part of the device to a piezo
transducer at the bottom of the ultrasonic cuvette.
The ultrasonic cleaning can increase the time between cleanings significantly. However it cannot
substitute the manual cleaning entirely.
2.3 Nameplates
