PRO 3-in-1 (pH, ORP, Temperature) Waterproof Testers with ATC

The Milwaukee pH58 MAX Waterproof 3-in-1 pH/ORP/Temp Tester delivers accurate, reliable measurement of pH, ORP, and temperature in a rugged, lightweight 3.5-ounce IP65-rated design. Accurate to ±0.05 pH and ±2 mV across an extended range of -2.00 to 16.00 pH and ±1000 mV, the pH58 is well suited for beer, food, wine, water treatment, pool management, education, and many other applications where ORP measurement alongside pH is needed. It features a gel-filled double junction replaceable MI58P electrode, two sets of pre-memorized calibration buffers, and a large dual-level LCD display with stability indicator and hold function for easy, accurate readings.

Features:

• Measures pH, ORP, and temperature; pH range -2.00 to 16.00; ORP range ±1000 mV; temperature range -5 to 60°C (23 to 140°F)
