JUMO ecoLine NTU Optical Turbidity Sensor

Name: JUMO ecoLine NTU Turbidity Sensor – Datasheet & Price Quote
Brand: JUMO

Description

Overview

JUMO ecoLine NTU is an optical sensor engineered to measure turbidity levels in aqueous solutions across a wide 0 to 4000 NTU measuring range, split into four selectable measuring bands to suit applications from ultra-clear drinking water to heavily loaded wastewater streams. The turbidity value measured by the JUMO ecoLine NTU is transmitted digitally and without interference to a connected JUMO AQUIS 500 RS indicating device, which provides an integrated controller along with analog and switching outputs for direct process control.

Backed by manufacturer datasheet documentation, Seven Star LLC proudly supplies the JUMO ecoLine NTU to municipal water authorities, wastewater treatment operators, and aquaculture facilities across Oman and the GCC. Customers purchasing through Seven Star LLC receive a formal quotation, the manufacturer datasheet, and technical support based in the Sultanate of Oman, supporting dependable turbidity monitoring in every installation.

Measurement Principle

The JUMO ecoLine NTU determines turbidity using the 90° scattered-light principle specified in DIN EN ISO 7027, in which an infrared light source at 880 nm is directed into the measured medium and a detector positioned at 90° to the beam captures the light scattered by suspended particles. The intensity of this scattered light is directly proportional to the concentration of suspended solids in the water, allowing the sensor to report a turbidity value with a measuring error of less than 5% of the displayed reading and a resolution as fine as 0.01 NTU depending on the selected measuring range.

Because the measurement relies on optical scattering rather than physical contact with a moving part, the JUMO ecoLine NTU introduces no mechanical wear into the measurement path and maintains accuracy across long unattended deployment periods. An integrated NTC temperature sensor accompanies the turbidity measurement, and the sensor’s calibration data and calibration history are stored directly in its onboard electronics, enabling fast on-site startup or sensor replacement without requiring a full recalibration in the field.

Engineering Design of the JUMO ecoLine NTU

The JUMO ecoLine NTU is built into a compact 27 mm diameter, 170 mm long PVC probe body rated IP68 and capable of withstanding process pressures up to 5 bar, making it suitable for continuous submersion in open channels, tanks, and fish farm enclosures. The sensor communicates over an RS485 digital interface, transmitting both the turbidity reading and diagnostic data to the JUMO AQUIS 500 RS indicating device without the signal degradation risk associated with analog transmission over long cable runs.

The sensor’s low-maintenance design is supported by a calibration logbook that records the last ten successful calibrations in a ring buffer directly within the sensor electronics, giving operators a traceable calibration history independent of the connected transmitter. Operating temperature is rated from 0 to 50°C, and the sensor is supplied with a fixed cable in 10 m or 30 m lengths to match typical mounting distances between the measuring point and the control cabinet.

Key Features

The JUMO ecoLine NTU delivers accurate, low-maintenance turbidity monitoring across a broad range of water quality applications. Key characteristics include:

Wide overall measuring range of 0 to 4000 NTU, split into four individually selectable measuring bands.
90° scattered-light measuring principle at 880 nm per DIN EN ISO 7027, with measuring error under 5% of the displayed value.
Integrated NTC temperature sensor alongside the turbidity measurement channel.
IP68-rated PVC housing rated to 5 bar, suitable for continuous submersion in demanding environments.
RS485 digital interface for interference-free signal transmission to the JUMO AQUIS 500 RS.
Onboard calibration data and a ten-calibration logbook stored directly in the sensor electronics.
Resolution as fine as 0.01 NTU, depending on the selected measuring range.
Available with 10 m or 30 m fixed cable lengths for flexible installation.

Industrial Applications

The JUMO ecoLine NTU is deployed extensively in municipal and industrial sewage treatment plants for effluent quality monitoring, in the protection of natural water bodies where turbidity limits govern discharge compliance, and in fish farm operations where water clarity directly affects aquatic health. Its wide measuring range and rugged IP68 housing also make it well suited to process engineering plants handling variable-turbidity process water, where continuous, low-maintenance monitoring reduces the operational burden on plant personnel.

Working closely with plant engineers in the region, Seven Star LLC distributes the JUMO ecoLine NTU to desalination plants, municipal utilities, and aquaculture operators throughout Oman and the wider GCC, including facilities within the Sohar and Salalah economic zones. Regional customers benefit from sensor and fitting selection guidance and access to JUMO’s engineering documentation through Seven Star LLC’s technical instrumentation division.

About brand

JUMO is the German maker of temperature sensors, process controllers, pressure transmitters and liquid analysis instruments. Moritz Kurt Juchheim founded it in Fulda in 1948 as M. K. Juchheim KG, making glass thermometers with six employees. The name JUMO comes from the founder's name. It is still a family company headquartered in Fulda, and the parent company has been called JUMO GmbH & Co. KG since 2003.

Seven Star LLC is an independent supplier in Muscat. We list JUMO RTD and thermocouple probes, thermowells, transmitters, controllers, recorders and water analysis instruments, and supply them to process plants, OEMs, HVAC contractors and water utilities in Oman and the GCC by type number.

Choosing a temperature sensor starts with the range and accuracy. A Pt100 RTD is accurate and stable from about -200 to 600 °C and is the usual choice in process plants. A thermocouple (type K or J, for example) covers much higher temperatures and responds faster but is less accurate. The wiring also matters: a 3-wire or 4-wire Pt100 connection cancels the resistance of the cable, while a 2-wire connection adds an error that grows with cable length. That is why a head-mounted transmitter is often fitted close to the sensor.

Where JUMO products are used

In Oman and the GCC, JUMO sensors and controllers are used in oil and gas and chemical plants, food and beverage production, plastics and metal heat treatment, HVAC and district cooling, water and wastewater treatment, swimming pools and marine applications.
