Water / Wastewater 21 New TOC analysers for monitoring low-TOC values precisely and reliably
Endress+Hauser have augmented its liquid analysis portfolio in the life sciences, power & energy, semiconductor manufacturing, personal care, and disinfectant production sectors with the CA78 and CA79 online TOC analysers, ensuring high water quality and safe operating conditions.
Total organic carbon (TOC) is an important quality parameter in the various manufacturing and process environments that depend on ultrapure water. When TOC content is too high, it can adversely impact the performance of water treatment systems, compromise high-precision machinery, or contaminate batches. The CA78 and CA79 online TOC analysers provide continuous and precise monitoring to ensure stable operations, regulatory compliance, and high-quality products. These TOC analysers utilize proven UV-oxidation and differential conductivity measurement, the most-established method for reliable TOC trace analysis in ultrapure water. The fast response time (t90) of 50 seconds enables quick control system and personnel reaction in the event of water quality deterioration, reducing contamination, product loss, and costs.
The analysers’ user-friendly modular design and easy accessibility to components simplify maintenance and minimize operating costs. Additionally, Endress+Hauser’s worldwide service network provides end users with complete measuring point management throughout plant lifecycles, including installation qualifi cation and operational qualifi cation. The CA78 TOC analyser supports safe operations in many applications, such as protecting turbines and other expensive power plant equipment, manufacturing semiconductors and additional microelectronics, ensuring product quality in the personal care industry and assuring the effi cacy of disinfectants.
The CA78 is confi gurable to meet various requirements in the power and semiconductor industries. For example, the standard version is the right choice for measuring ultrapure water in semiconductor production, providing high-precision measurement in water with conductivity values up to 2 µS/cm. Meanwhile, the instrument option for measurement in water with conductivity values closer to 10 µS/cm is perfectly suited for deionized water in power plants. When multiple TOC measuring points are required, the 3-channel confi guration allows for multiple streams to be run through one analyser, which reduces capital expenditures.
With the introduction of the CA78 and CA79 analysers for low-TOC measurement ranges, Endress+Hauser is rounding out its liquid analysis solutions for critical parameter measurement.
The CA78 supplements Memosens CLS15E contacting conductivity sensors, Liquiline System CA80SI silica analysers, CA76NA sodium analysers, and SWAS panels for reliable, low-maintenance solutions in a variety of sectors. The CA79 complements the Memosens CPS61E pH sensor, Memosens COS81E oxygen sensor, and Memosens CLS82E conductivity sensor for critical parameter measurement in pharmaceutical production environments.
These analysers each store critical process, calibration, and sensor data locally, with transmission to a central process control and documentation hub, which is especially important in highly regulated industries. This plethora of high-precision instruments provides end users with a complete portfolio of sensors, photometers, and TOC analysers, and now all of these measurements can be monitored and managed at a single source.

Award winning pH sensors impress at WWEM exhibition
Following a very successful WWEM, award winning ANB Sensors (Top Ocean Tech Service Provider 2022) unique and ground-breaking calibration-free pH sensors are now available for the water
industry. While the industry standard glass electrode is the most widely used pH sensor it has a basic operational fl aw, it requires human calibration to account for signal drift during deployment. The wastewater and environmental monitoring industries require a smarter, more cost effective, reliable and robust solution that can operate autonomously with minimal maintenance.
ANB Sensors are redefi ning pH sensing through their low cost, smart, self-calibrating pH Sensor for use across all platforms. This can be easily networked to IoT devices and has running costs that are 70% lower than current sensors.
The calibration-free pH Sensors are available from depths of 5m to 1250m. Please visit www.

A Cost-Eff ective Solution for Water
Quality Requirements Myron L®
Company’s 900 Series multi-parameter water quality monitor/controller is easy to install, easy to use, and does the job of seven separate instruments single-handedly.
Precisely monitor and control an array of critical water and wastewater parameters with the legendary accuracy and reliability the Myron L Company has come to be known for. The 900 Series Monitor/Controller features a simple-to-use LCD touchscreen Graphical User Interface along with pluggable terminal blocks for quick and easy equipment installation and confi guration.
Get a comprehensive real-time picture of solution status with continuous readings from up to seven different inputs: 2 Conductivity/Resistivity/TDS/Salinity; 1 pre-amplifi ed pH/ORP; 1 BNC pH/ORP; 1 fl exible 0-20/4-20 mA; 1 RTD Temperature; and 1 Flow/Pulse. % Rejection is also available as a derived value. For maximum accuracy, Conductivity/TDS measurements feature the ability to select from one of three preprogrammed solution modes, KCl, NaCl, or Myron L’s own 442 Natural Water™ Standard, or to program a “User” solution mode based on a known solution. Temperature compensation is automatic to 25°C but can be disabled by the user as required. The pH/ORP input channel works with Myron L pre-amplifi ed pH and ORP sensors which contain precision circuitry that increases accuracy and permits application of the sensors over greater distances. The 0-20/4-20 mA input allows user-defi ned 0 to full scale values and units of measure for a wide variety of sensor types. Electronic or wet calibrations are easy to perform.
Automatically trigger control equipment and audible signals and continuously report and record solution data with fl exible outputs. The 900 features up to 3 relays; 2 remote alarms; 1 0-20/4-20 mA signal; 1 0-5/0-10 VDC signal; and 1 RS-485 ASCII serial signal. Relays output to any user-supplied control equipment requiring up to 250V each and can trigger on any input parameter. The 0-20/4-20 mA output can transmit a signal for any input parameter. 0-5/0-10 VDC can be scaled to optimize resolution and can output to a recorder, PLC, SCADA system, etc. 0-1 VDC is possible with optional resistor.
Myron L also backs these instruments up with expert dedicated technical support that assures installation and operation success. More information online:
