Product Overview
E+H Liquisys CPM223 Industrial Panel-Mount pH/ORP Transmitter
CPM223-MR0005
The CPM223-MR0005 is a high-performance panel-mounted pH/ORP transmitter designed for continuous liquid analysis and precise dosing control in demanding industrial water treatment and chemical processes, supporting both traditional analog and digital smart sensors with 230V AC power supply, real-time sensor diagnostics, and active 4-20mA signal transmission.
The CPM223-MR0005 pH/ORP Transmitter is an industry-standard panel-mounted liquid analysis controller engineered for continuous, high-precision monitoring of pH and oxidation-reduction potential in complex process environments. Built into a compact 96×96 mm polycarbonate housing with IP54 front protection, this versatile instrument provides robust measurement stability across municipal water treatment, chemical manufacturing, power generation, and industrial effluent monitoring systems. It seamlessly interfaces with both conventional analog electrodes and modern digital Memosens sensors, offering continuous self-diagnostic capabilities through integrated Sensor and Process Check Systems that automatically detect glass breakage, electrode fouling, or signal loss to eliminate process downtime. Featuring an intuitive backlit LCD interface with simple two-point buffer calibration, active 4-20mA analog output, and configurable alarm relay contacts, the CPM223-MR0005 delivers end-to-end operational safety, effortless automation integration, and long-term maintenance cost reductions for global plant operators and system integrators.
FAQ
Q1: Is the CPM223-MR0005 compatible with pre-calibrated digital Memosens sensors?
Yes. The CPM223-MR0005 fully supports digital Memosens pH/ORP sensors. Pre-calibrated sensors can be calibrated in the laboratory and connected in the field using plug-and-play functionality without field re-calibration.
Q2: What panel cutout size is required for mounting?
The device fits standard 92 x 92 mm panel cutouts with an overall front bezel dimension of 96 x 96 mm (1/4 DIN panel cutout standard).
Q3: Can you supply complete sensor packages (electrodes, flow cells, and cables) together with the transmitter?
Yes. As an automated instrumentation manufacturer, we provide complete liquid analysis packages, including compatible pH/ORP glass/digital electrodes, immersion/flow housings, temperature compensation probes, and signal cables.
Q4: Do you offer OEM / ODM customization, white-labeling, or volume discounts for distributors?
Absolutely. We support custom branding, private labeling, specific enclosure color options, and bulk pricing for OEM partners and global distributors. Contact our sales engineering team for detailed quotations and technical specifications.
