/VIS
is therefore based on fun and intuition, creating an unrivaled user experience in the laboratory. On the technical side, the NANOCOLOR® UV
/VIS II impresses with clever mechanics and optics. The spectral bandwidth has been reduced below 2
nm, providing added measurement accuracy. The wavelength resolution goes down to 0.1 nm, adding another level of precision to scans and measurements in general. Internal stray light is kept to a minimum of below 0.05 %, thus achieving a particularly clear measurement signal.
Obviously, the NANOCOLOR® UV while measuring NANOCOLOR®
/VIS II features the well-known and proven bar-code technology to quickly measure our NANOCOLOR® standard tests or pre-programmed methods is easily done as well.
tube tests,
The entirely new scan menu allows you to not only scan in real time at different resolutions, but to perform in depth analyses of the scans. The customer can highlight peaks and valleys, add and subtract scans and generate high quality images with no additional software or complex programming.
As a unique aspect of all MACHEREY-NAGEL spectrophotometers the NANOCOLOR® UV /VIS II also features an integrated NTU measurement
function, however, it has been significantly enhanced in the new instrument. The sensitivity has been increased to astonishingly low levels of 0.1 NTU now, enabling turbidity measurements even for drinking water applications. Additionally, our ingenious
NTU-Check function brings additional safety to the user in the NANOCOLOR® UV with every tube test measurement.
/VIS II as well, featuring optional, instant NTU turbidity detection Another highlight that has been integrated into the instrument is its ability to measure color. The NANOCOLOR® UV /VIS II an extremely powerful analytical tool, which is unparalleled in the market. /VIS II features a built-in color
measurement mode, that allows users to run color applications such as CIE L*a*b*, Hazen, ADMI and others. All the added functions make the NANOCOLOR® UV
All in all, MACHEREY-NAGEL launches an instrument that sets new standards for an entire industry in terms of innovation and intuitive use. The instrument is infused with MACHEREY-NAGELs passion for quality, precision and accuracy, while adding a new level of simplicity to customers’ daily work.

De-Chlorination Analyser Measures Near Zero Levels of Chlorine for Repeatable Accuracy
For More Info, email: email:
Municipal water system and industrial process engineers in search of an analyser that accurately measures near zero levels of chlorine will want to learn more about the plug-n-play DC80 De-Chlorination Analyser from Electro-Chemical Devices (ECD), which utilises a zero-shift method to ensure stable and reliable chlorine measurement.

Conventional amperometric chlorine sensors are unstable when measuring near zero amounts of chlorine, which can lead to inaccurate and inconsistent readings. The DC80 De-Chlorination Analyser utilises a “zero-shift” methodology to provide accurate measurement and to protect total chlorine sensors from damage, which naturally occurs when the water samples measured contains near zero or zero levels of chlorine.
For example in wastewater treatment when monitoring for chlorine just before outfall, there can be no chlorine present and yet measurement is still necessary. If there is no chlorine present then the electrode becomes unstable and finally unresponsive. Therefore the very process of measuring de-chlorination becomes problematic. If all of the chlorine is removed then the sensor will provide an inaccurate reading after a few hours and fail after a few days still reporting zero chlorine
The DC80 De-Chlorination Analyser solves this problem: It is a total chlorine analyser that uses the “zero shift” strategy to monitor near zero amounts of total chlorine. Chlorine is metered into the sample shifting the zero from a near zero chlorine concentration to a measurable value. The analyser’s offset feature allows the metered value to be subtracted from the measurement.
The DC-80 De-Chlorination Analyser monitors chlorine in drinking water, wastewater, cooling water and other de-chlorination applications from 0.05 – 20 ppm. Its mounted system includes built-in flow control, which eliminates the need for complicated plug-and-play design installs quickly right out of the box. The DC80’s advanced panel pressure regulators and rotometers. Built-in automatic pH compensation for samples between 4 and 12 pH also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.
The analyser’s total chlorine sensor is a three electrode amperometric sensor with a gold cathode, silver halide anode and 304 stainless steel counter electrode. The counter electrode provides a stable base potential that minimises drift for superior accuracy. The total chlorine sensor has a micro- porous membrane that allows ions to diffuse in and out of the sensor.
The analyser’s pH sensor provides accurate compensation for samples between 4 and 12 pH, which eliminates the need for a sample conditioning system. The total chlorine sensor graphically displays both the total chlorine and pH levels for easy trend analysis.
The DC80 Analyser is available with either 110-240 VAC or 24 VDC power. The standard configuration features dual measurements, two 4-20 mA outputs and three alarm relays. The user friendly DC80 also is available with an auto clean option that includes a solenoid actuated spray cleaner using either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.

Endress+Hauser (USA) releases Liquiline To Go CYM290 and CYM291 portable handheld multiparameter monitors for use with analogue and digital sensors. Each device automatically detects when any Memosens sensor is connected and switches to the appropriate measured variable. By simply plugging a Memosens sensor into the monitor, a technician can measure conductivity, ORP, pH or oxygen. The battery- powered monitor also displays sensor type, serial number, zero point, slope and date of calibration for the sensor.
Liquiline To Go monitors permit a technician to enter a process area, connect the monitor into any Memosens sensor, read the measured value, transfer all data into the monitor, and calibrate the sensor. This can be especially useful when installing new sensors in the process, when conducting regular maintenance checks, or when performing calibrations in the measuring laboratory. Performing these operations with a Liquiline To Go monitor guarantees full data consistency because it allows the use of the same measuring technology in the laboratory and in the process.
pH, ORP, conductivity and oxygen sensors from Endress+Hauser with Memosens technology have integrated electronics that allow for saving calibration data, total hours of operation, and operating hours under extreme measuring conditions. Once the sensor has been connected to the Liquiline To Go monitor, this data is transferred automatically to the portable monitor and used to calculate the measured value. Because calibration data is stored in the sensor, the sensor can be calibrated and adjusted independently of the measuring point. Data transferred to the monitor can be downloaded into a maintenance management program for further analysis.
Memosens is an inductive, non-contact connection used to connect the sensor to the monitor for maximum process safety. The non- contact connection also eliminates moisture and corrosion issues, and even allows the monitor to be connected under water. The CYM291 monitor is IECEx and ATEX certified for use in hazardous areas up to Ex Zone 0, and both models have IP66/67 ingress protection with pressure compensation.
