Myron L Ultrapen PT5 Dissolved Oxygen (DO) & Temperature Pen sodium meter The sensitivity dial helps tuneThe Myron L Ultrapen PT5 measures dissolved oxygen and temperature in a pocket sized, waterproof pen. It uses an optical (luminescent) DO sensing approach that needs no membranes to replace and no electrolyte to refill, so there is far less to maintain than on a traditional Clark cell DO meter and no stirring dependency to bias a reading. Application Suited to groundwater and surface water sampling, low flow purge monitoring, aquaculture and fish
