Easy-to-use, the Seven Go Duo pH/conductivity meter is essential for all analysis specialists, and is particularly adapted to the food industry. This dual-channel portable instrument measures simultaneously 2 parameters (pH and conductivity). Seven Go Duo pH/Conductivity meter is delivered in a field kit, including 2 electrodes (pH and conductivity), IP67 protection case, and a 2-meter cable for each electrode, calibration sachets for pH and conductivity, sample flasks, a clip for 2 electrodes, and the carrying case.
