DO 6+ Meter

High accuracy combined with economical pricing

  Low-maintenance, galvanic probe requires no warm-up time
  Includes protective rubber boot which also functions as a benchtop stand

These meters provide a great value. The ranges work to test water quality in wastewater, surface water, ground water, or drinking water. A clear LCD display shows results in ppm or mg/L with enunciators to aid in use and troubleshooting. Six simple buttons allow for freezing readings, toggling between display units and temperature results, setup, calibration, and automatic barometric and salinity compensation after manual parameter inputs. Additional benefits of the simple design allow you to view electrode slope, zero offset, and millivolt values for electrode diagnostics.
