This kit includes:

  • The waterproof meter,
  • 3 calibration standards,
  • 3 pH buffer pouches
  • Rinse solution,
  • 3 cups,
  • Batteries
  • Hard carrying case.

Included is everything you need to use this meter effectively and accurately.

This 5 in 1 multi range sensor easily measures the electrical conductivity, the pH, the total dissolved solids (TDS), the salinity and the temperature all in one easy to use meter. This meter is excellent because it saves you money and gives you precise digital readings. This meter is auto ranging with 8 selectable units including µS/cm, mS/cm, ppm, ppt, mg/L, and g/L. The rugged flat surface pH electrode gives you an accurate and repeatable reading every time.

Features an adjustable conductivity to TDS ratio factor from 0.4 to 1.0 which conveniently calculates the TDS value. Displays an analog bar graph so you can follow measurement trends. Also holds your data and has an auto power off and low battery indicator. The display simultaneously shows conductivity or TDS plus the temperature.

The internal memory stores up to 25 labeled readings for easy recall and to limit the need for retesting. This also has a handy self calibration feature upon power up. This waterproof meter means you can use it in the field without worrying about damp or wet conditions. Also comes with conductivity cell, sensor cap, sample cup with cap, four 3V CR2032 button batteries and 48" neck strap.
