• Multi-parameter probe for measuring pH, conductivity, TDS, and temperature in water testing applications
• Replacement probe for the Milwaukee Mi805 and Mi806 meters (both sold separately)
• Comes with a built-in amplifier to help prevent electrical interference
• PVC body for corrosion resistance

The Milwaukee MA851D/1 probe is a multi-parameter probe for measuring pH, conductivity, total dissolved solids (TDS), and temperature for automatic temperature compensation (ATC) in water testing applications. This is a replacement probe for the Milwaukee Mi805 and Mi806 meters (both sold separately). It contains a single-junction silver/silver chloride (Ag/AgCl) reference electrode that is sealed and filled with an electrolyte solution gel for minimal maintenance in general applications, and it comes with a built-in amplifier to help prevent electrical interference. It has a PVC body that resists corrosion, is 20mm in diameter and 110mm long, and has 1m cable with 7-pin Deutsches Institut für Normung (DIN)-compliant connector for attaching to the meters.
