Conductivity Solutions

Don’t worry if you drop the waterproof OAKTON^® TDSTestr in a tank or pond because it floats! These Testrs can also be certified to meet IP67 ratings for dustproof and waterproof ingress protection.

The Waterproof TDSTestrs show full scale readout on the display so there is no need to multiply the readout to obtain actual test values. TDSTestr 1 and 2 read directly in ppm or ppt for total dissolved solids; TDSTestr 3 and 4 read directly in µS or mS for conductivity.
