Handheld Monitors for Measuring pH, ORP, Conductivity and Oxygen in Hazardous Areas

Endress+Hauser (USA) releases Liquiline To Go CYM290 and CYM291 portable handheld multiparameter monitors for use with analogue and digital sensors. Each device automatically detects when any Memosens sensor is connected and switches to the appropriate measured variable. By simply plugging a Memosens sensor into the monitor, a technician can measure conductivity, ORP, pH or oxygen. The battery-powered monitor also displays sensor type, serial number, zero point, slope and date of calibration for the sensor.

Liquiline To Go monitors permit a technician to enter a process area, connect the monitor into any Memosens sensor, read the measured value, transfer all data into the monitor, and calibrate the sensor. This can be especially useful when installing new sensors in the process, when conducting regular maintenance checks, or when performing calibrations in the measuring laboratory. Performing these operations with a Liquiline To Go monitor guarantees full data consistency because it allows the use of the same measuring technology in the laboratory and in the process.

pH, ORP, conductivity and oxygen sensors from Endress+Hauser with Memosens technology have integrated electronics that allow for saving calibration data, total hours of operation, and operating hours under extreme measuring conditions. Once the sensor has been connected to the Liquiline To Go monitor, this data is transferred automatically to the portable monitor and used to calculate the measured value. Because calibration data is stored in the sensor, the sensor can be calibrated and adjusted independently of the measuring point. Data transferred to the monitor can be downloaded into a maintenance management program for further analysis.

Memosens is an inductive, non-contact connection used to connect the sensor to the monitor for maximum process safety. The non-contact connection also eliminates moisture and corrosion issues, and even allows the monitor to be connected under water. The CYM291 monitor is IECEx and ATEX certified for use in hazardous areas up to Ex Zone 0, and both models have IP66/67 ingress protection with pressure compensation.
