Titration Analyzer Measures Alkalinity Automatically

The IoT web-enabled CA900 Titration Analyzer from Electro-Chemical Devices (ECD) allegedly automates the process of routine alkalinity measurement with a simple, accurate, and cost-effective approach. The unit is said to install and start up easily in less than 15 minutes. All that is necessary are simple connections of the sample, waste and reagent lines and then powering up the factory pre-calibrated analyzer. Wall mounting hardware comes standard with each analyzer, but an optional bench top stand with reagent holder also is available.


Four different ECD factory pre-set alkalinity calibration ranges are available: 0 to 50 ppm, 50 to 200 ppm, 200-1000 ppm, and 0 to>1000 ppm. Users order the desired calibration range, and the analyzer comes ready to go right out of the box. The analyzer’s full-featured design also comes with four 4-20 analog outputs, an Ethernet digital output, and four user-configurable alarm relays. Other features include a user-friendly menu structure and touchscreen interface. The analyzer also can be web-enabled as an internet of things (IoT) tool for remote monitoring and interfacing with personal handheld devices such as controllers, mobile phones, tablets, laptops and computers.


Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.


The CA900 Titration Analyzer typically performs a single alkalinity measurement per analysis cycle.  Its standard program sequence consists of a cleaning cycle, sample acquisition, monitoring of pH, the addition of the titrant fluid, mixing the fluid, calculation of results and data storage.  The desired frequency of analysis between cycles can be easily modified to the requirements of the user’s process.
