Optical Turbidity Measurement with the
JUMO ecoLine NTU Sensor
Introduction of a new measurand at a proven level of
quality
The turbidity measurement according to DIN EN ISO 7027 is
an efficient and widespread measurement method for
controlling and determining quality (particularly of water
with low to medium turbidity). Due to the optical turbidity
sensor ecoLine NTU, JUMO can now offer such a method.
The measurement and control technology specialist is
extending its program of sensors for liquid analysis by a
new measureand while at the same time expanding its offer
of optical and digital measurement methods.
The measuring principle of the JUMO ecoLine NTU is based on an
infrared light measurement according to the 90° scattered light
principle. Thanks to turbidity measurement for a wavelength of
880 nm and a measuring range of 0 to 4000 NTU, the sensor is
suitable for application in numerous fields. Drinking water
monitoring, municipal and industrial wastewater treatment, final
wastewater inspection, monitoring bodies of water, or application
in fish farming operations are just some examples.
The sensor is suitable for operating temperatures of 0 to 50 °C.
The sensor housing is made of PVC and is characterized by its
sleek and robust design. The calibration data and the calibration
history are stored in the implemented electronics. This allows rapid
deployment without the constant need for recalibration. Both
immersion and flow fittings are available as accessories.
The JUMO ecoLine NTU is connected via the RS485 digital
interface to the JUMO AQUIS 500 RS indicator/controller and
can therefore be deployed on-site as a complete measuring unit.
The JUMO AQUIS 500 RS also has two analog outputs and two
switching outputs. As a result, the device is ideally suited for
connection to superior systems. Plain text displays make
operation easy. Furthermore backlighting enables the display to
be read even under adverse light conditions.
