pH Sensor for Water

The SE 515 is the ideal pH sensor for water and wastewater treatment applications. The Memosens sensor is designed to withstand plugging media, low temperatures, and be reliable in low-ionic media. Additionally, an integrated NTC 30K temperature element assures that all pH measurements are accurately compensated for the process media temperature. The sensor’s gel electrolyte does not require refilling, making this a low-cost and low-maintenance pH sensor for water and wastewater applications. The SE 515 is suitable for use with any Memosens transmitter. However, when paired with the MemoRail transmitter, it provides for one of the lowest-priced digital pH measurement loops on the market.

ISFET pH Sensor

Our ISFET pH sensor is break-resistant and utilizes Memosens digital technology. The glass-free sensor is ideal for pharma, biopharma, cosmetics, food & beverage applications with CIP/SIP cycles. Additionally, the integrated NTC 30K temperature element accurately compensates for the process temperature. The acrylamide-free reference gel does not require refilling, so the sensor is a low-maintenance pH sensor for hygienic and sterile applications. Additionally, this ISFET pH sensor is suitable to use with any Memosens transmitter.

Transmitters & Automated Systems - Transmitters & Analyzers

DIN Rail-Mounted, Multi-parameter Memosens Transmitter

MemoRail is a compact, digital transmitter for the measurement of pH, ORP, conductivity, oxygen, and temperature when connected to Memosens® sensors. Two analog active/passive 4 … 20 mA outputs supply the measurement values to a process control system. MemoRail is a low-cost, space-saving, alternative to traditional liquid analyzers – 17.5 mm wide.

DIN Rail-Mounted Memosens Transmitter with Modbus RTU

MemoRail Modbus is a compact, digital transmitter available with up to 2 sensor inputs. It operates with the SE 740 optical oxygen sensor and Memosens sensors for pH, ORP, conductivity, oxygen, and temperature. Furthermore, up to 32 Modbus RTU devices can operate in parallel. Device address, link parameters, and data rate are selectable. MemoRail Modbus is a low-cost, space-saving alternative to traditional liquid analyzers.

4-Wire Analog Transmitter

The Stratos Eco analyzer is a basic device for analog pH, ORP, conductivity, or dissolved oxygen sensors in almost any standard industrial application. The intuitive menu navigation and large terminal compartment inside the pre-assembled cabinet make the Stratos Eco simple to implement in any plant or process.
