The edge family are tablet-style meters that can be used as a benchtop, wall-mount, or portable meter. The edge meters offer many advanced features including automatic calibration and automatic temperature compensation of readings. All edge meters have a Good Laboratory Practice (GLP) mode to review calibration information include the data and time of the last calibration. The edge meters can log data and transfer data through either a USB port for a flash drive or a micro-USB port when connected to a computer.
For pH measurement, the edge meters offer CAL Check. The CAL Check feature identifies potential problems during the calibration process, such as clean the electrode, check the buffer for contamination, and the overall “health” condition of the electrode. For pH the edge meters are available as a dedicated and Bluetooth version for pH only and a multiparameter version that can accept either a EC or DO probe.
For EC measurement, the edge meters offer automatic temperature compensation and range selection. The edge meters are also able to measure TDS and salinity. The edge user can set the EC to TDS conversion factor, temperature coefficient, and type of salinity to be measured. For EC, the edge meters are available in a dedicated version for EC/TDS only or a multiparameter version that can accept either a pH or DO probe.
For DO measurement, the edge meters offer automatic temperature compensation and manual selection for altitude and salinity compensation. For dissolved oxygen, the edge meters are available as a dedicated version for measuring only DO or a multiparameter version that can accept either a pH or EC probe.
