Endress+Hauser Memosens liquid analytical sensors

Endress+Hauser has launched five laboratory sensors compatible with its Liquiline CML18 handheld laboratory analysis device. The Memosens CPL53E, CPL57E, CPL59E, COL37E and CLL47E liquid analytical sensors support data and quality management in the verification processes of online measurements, providing immediate and tamper-proof calibration history traceability with easy data transfer using Bluetooth technology.

Using the bayonet connector, the handheld CML18 and Memosens sensors work out of the box with support switching output parameters — such as pH, dissolved oxygen and conductivity — at the measuring point. Users can begin making measurements without initial calibration because the instruments are pre-calibrated at the factory. The sensors are suitable for laboratory measurement and random process grab sampling.

The CPL53E glass pH sensor is built for all-around use in the lab, covering everything from lab sampling to random process grab sampling. It has a measurement range of pH 0 to 14, a process temperature range of -5 to 100°C and an application range of 0 to 80°C.

The CPL57E pH sensor is designed for low-conductivity water applications. The glass sensor provides long-term stability because of additional salt storage, providing high measurement accuracy in pure water from pH 0 to 14, a process temperature range of -5 to 100°C and an application range of 0 to 80°C. Like the CPL53E, it is virtually maintenance-free.

The CPL59E pH sensor is built to withstand harsh conditions in chemically aggressive fluids, specifically within the measurement range of pH 0 to 14, with a process temperature range of 0 to 135°C and application range of 0 to 100°C. With an ion trap, the instrument provides high stability to oxidising agents, protecting the sensor from drift.

The digital COL37E dissolved oxygen sensor enhances oxygen measurement with a fast response time. With a measurement range of 0 to 200 %sat and process temperature range of -5 to 60°C, the sensor is primed for use in checking oxygen values in aeration tanks, fish farms and surface water.

The CLL47E is a four-electrode conductivity sensor for random sampling and measurements in the lab with a measurement range of 5 μS/cm to 200 mS/cm and a process temperature range of 0 to 100°C. Four platinum electrodes allow for coverage over a large variety of samples. The sensor is designed to provide high precision at measuring point in drinking water, cooling water, wastewater and process media.
