Calibration software for pH, oxygen, conductivity and chlorine sensors Endress+Hauser introduces Memobase Plus calibration software for pH, oxygen, conductivity and chlorine sensors. The software turns a PC into a calibration laboratory, providing complete traceability of test solutions, sensors, calibrations and measurements. Calibration reports are generated automatically as a PDF document or a CSV file that can be exported to Excel or similar software for further processing. An audit trail, user administration settings and passwords ensure security. The software is FDA 21 CFR Part 11 compliant. The product is capable of managing four different sensor types simultaneously: pH (glass and ISFET); dissolved oxygen; ORP, conductive and inductive conductivity; and chlorine. The software provides guided, step-by-step instructions for the correct calibration procedure required by each sensor. A Live-Graph function provides visual control during the calibration, enabling appraisal of sensor condition. It also provides full traceability of all testing equipment and reference solutions. ‘As found, as left’ measurements can be performed to assess measurement uncertainty before calibration. Memobase Plus constantly monitors Memosens sensors and keeps logs to document the entire sensor life cycle. It maintains time stamps for adjustment and deactivation with explanations, an operating hours counter to help analyse sensor condition and a calibration timer to help schedule calibrations. Operators can view a numerical and graphical display of primary and secondary measured values with a zoom function and a time bar. Reports include all the information required for sensor calibration, maintenance and audit trails. Reports are subdivided into Measure, Calibrate, Sensors and Reference Solution categories for fast retrieval of specific data. A sorting and filter function helps users find data more quickly.

Multiparameter portable meters Hanna Instruments has announced the release of several waterproof multiparameter portable meters. The meters have up to six sensors for measuring pH, ORP, EC, DO, temperature and barometric pressure, in addition to seven interpreted parameters including TDS, seawater salinity and pH in mV. The meters are tough, compact and lightweight, yet provide the ability to measure critical water parameters with laboratory-grade accuracy. The pH, ORP, EC and DO sensors are field replaceable and mount into a single digital probe that is around 5 cm in diameter. The sensors are protected by an ABS plastic cage that is weighted with a stainless steel ring, allowing for the probe to achieve a maximum depth of 20 m in water. The HI98194 (pH/ORP/EC/ DO/temperature/barometric pressure), HI98195 (pH/ORP/ EC/temperature) and HI98196
