Description

Save time, space and money with the Starter 3100M Bench Meter, which combines all your pH, ORP, conductivity, TDS, salinity, resistivity and temperature measurements - in one smart device. Ideal for a wide range of lab applications, the ST3100M is incredibly easy to use. Equipped with software to ensure the reliability of your readings, and RS232 connectivity to store and transfer data conveniently, the ST3100M is a great addition to your lab.

Auto temperature compensation, auto buffer recognition, six pH buffer groups, five conductivity standards and automatic/manual endpoints ensure accurate and stable measurement.

An adjustable electrode holder, a large backlit LCD for optimal viewing of results, and a Quick Guide with setup and navigation info combine to make ST3100M a truly user-friendly experience.

Documenting data is made efficient with a 99-item memory for pH and conductivity measurements. RS232 interface allows you to connect to an external device such as a printer to store or transfer data.
