Manta+20
The Manta+20 comes standard with temperature, pH, conductivity, and dissolved oxygen sensors, and optional ORP and depth sensors.  The M+20’s optical DO sensor features a long-life (5+ years) replaceable cap, and the pH sensor includes a refillable pH reference.  Eliminating expensive consumables ensures low cost of ownership over the life of the probe. Connect the MantaPlus 20 to any of our field display options for sampling in the field, or add a battery pack for autonomous deployments.  Connect to a telemetry station for viewing real time data in the cloud.
