Mettler Toledo has added a new range of multi-parameter portable meters for measuring pH, conductivity, dissolved oxygen and ion concentration. All three instruments are based on the rugged SevenGo design platform and are watertight according to IP67. This means they can withstand dusty, dirty or wet environments. The instruments include the SevenGo Duo SG23, a routine dual-channel pH/conductivity meter; the SevenGo Duo pro SG78, a professional meter for pH/ion/conductivity; and the SevenGo Duo pro SG68, a professional meter for pH/ion/dissolved oxygen.
