Ohaus Starter 300 Series Portable Water Analysis Meters

These Starter 300 Series Portable Water Analysis Meters can be operated in the lab with the support of a built-in stand, or in the field. They fit comfortably in the palm of your hand and have an easy-to-use, well-organized LCD screen with one-touch recall of calibration data and stored information. They are also equipped with IP54 protection which shields the meter from damage by water and dust particles. 

Choose from pH, Conductivity, or Dissolved Oxygen (DO) Meter-

Starter 300 pH Meter- Features automatic and manual temperature compensation to ensure accurate readings while a 30 measurement library stores for future reference. The auto buffer recognition stores calibration data and help to avoid errors during the calibration process. 

Starter 300C Conductivity Meter- The 30 item library allows users to store measurement data, and stored information and calibration data can be easily recalled with one touch.  The auto temperature compensation with adjustable temperature co-efficient for accurate measurements and 4-pole and 2-pole conductivity probes which offer a large conductivity range that safeguards them from effects of polarization and pollution. 

Started 300 D Dissolved Oxygen Meter- Features automatic or manual endpoints which allow the user to easily recall the last calibration data and stored information with one quick touch.  The galvanic electrode can be used immediately after being powdered on without the wait time typically associated with other DO meters.

All meters include IP54 Sets; Electrode Clip; Wrist Strap; and 4AAA Batteries.
