TOP TDS WATER TESTER 2026

A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality

TDS Meter: The TDS meter digital water tester is equipped with a premium titanium alloy probe that can quickly and accurately test the total dissolved solids (TDS) of water. With the water quality tester, you can quickly test the TDS value to help you understand the turbidity of your household water and maintain the health of your drinking water.

Measures electrical conductivity (EC), total dissolved solids (TDS). Exellent for nutrient testing – Four scales: EC: µS, mS; TDS: ppm, ppt – Automatic Temperature Compensation (ATC)

APERA’s unique BPB (Brush-resistant Platinum Black) probe ensures high accuracy and consistency in a wide-range conductivity measurement

Lightweight pocket-size water quality tester with vinyl case for easy travel storage. Auto reading, hold & auto shut off function. Provides the most accurate general water quality testing for most Drinking water

Accuracy: ±1% F.S, ±0.5˚C; Range: 0-10,000 ppm (10 ppt) EASY Auto Calibration with auto buffer recognition; 0 to 50˚C Auto. Temp. Large LCD with dual display of temp./ppt, and reminders of completed calibrations and stable readings

APERA’s unique Replaceable Platinum Black sensor ensures high accuracy and consistency in a wide-range conductivity measurement. EASY Auto. Calibration with auto buffer recognition; Auto Temp. Compensation (ATC) ensures accuracy in variant temperatures (0-50. 0˚C)

Measures electrical conductivity (EC), total dissolved solids (TDS), and temperature. Four scales: µS, mS, ppm, ppt (mS and ppt are new). Three different nonlinear ECtoTDS conversion factors (KCl, 442TM, NaCl).Waterproof housing (IP67 rating)
