Tester Combo 4

Tester Combo 4: All-in-One EC, TDS, pH and Temperature Tester

The tester can perform four independent measurements: electrical conductivity (EC), total dissolved solids (TDS), pH, and temperature. TDS coefficients are adjustable. It features a large, two-line display, a waterproof housing (it floats on water), and automatic temperature compensation. It has a stabilization indicator to ensure accurate readings and a HOLD function to freeze the displayed result on the screen.

Ranges: EC: 0...3999 µS/cm; TDS: 0...2000 mg/L (ppm); pH: 0.0...14.0; temperature: 0.0...60.0 °C.

No recalibration is required for every use (automatic calibration via buttons). The temperature probe is integrated and enables temperature measurement and temperature compensation. The electrode (probe) is replaceable - replacement with a new one is simple and quick.

Battery powered (4 x 1.5 V ≈ 100 hours of continuous operation); auto-off after 8 minutes of inactivity; battery charge indicator displayed.
