Oakton Waterproof TDS Tester 11+

The Oakton TDSTestr 11 Series TDS testers have large, easy-to-read two-line displays that show units, measurement status, and a battery life indicator. The replaceable electrode allows for reuse of the same meter body over and over. The tester's temperature readout simultaneously displays in °C or °F. The full reading is displayed; there is no need to multiply the readout to obtain actual test values. The tester features an adjustable (0.4 to 1.0) TDS factor to provide better accuracy. Simple push-button calibration is more precise than trimpot adjustment - no screwdrivers needed.
