  • Upgrades to design and function won't break the bank
  • Conductivity, TDS, and salinity in one meter
  • Expanded 4-digit dual-line display shows conductivity and temperature readings simultaneously
  • Additional key provides an easier, more intuitive interface
  • Improved cap functions as a sample cup and as a stabilizing base to stand the meter upright
  • IP67-rated housing is waterproof and floats
This new addition to the Oakton EcoTestr product line features updates to make measuring water quality easier and faster. The display is larger with a better viewing angle, has indicators for battery life, readiness, and calibration, and shows both the parameter and temperature readings at the same time.

To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being used—no more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup. It is also wider, providing a base to keep the meter upright for hands-free measurements.

The keypad now has a fourth key to simplify menu navigation while keeping convenient one-touch calibration. The new housing is compatible with lanyards to prevent losing or dropping, but is still waterproof and floats just in case.

  • Q:

    Does this come with any test water to calibrate it? Thanks

      This item will not come with any conductivity solution to calibrate with. That would need to be purchased separately. The most commonly bought is 1413 us which is item number 35653-11. It is best practice to purchase the calibration solution closest to what your closest expected measurement value would be.

Easy to use

Comments about Oakton EcoTestr CTS Pocket Conductivity, Salinity, and TDS Meter:

This item is very easy to use. The only issue we saw is that the unit arrived with the batteries in backwards and at first we thought it did not work until we opened and checked batteries. Once they were reinstalled properly we liked the ease of functionality.
