Description
the Milwaukee MW105 MAX Waterproof pH/ORP/Temp Portable Meter – a rugged, high-performance tool engineered for precise measurements in demanding environments. This IP67-rated meter offers a wide pH range of -2.00 to 20.00, ORP up to ±2000.0 mV, and temperature from -20.0 to 120.0°C, with excellent accuracy (±0.02 pH, ±1 mV, ±0.5°C). It features up to 3-point automatic calibration using 7 standard buffers, automatic or manual temperature compensation, and a built-in amplified pH/temperature probe (MA906BR/1) for reliable results even in viscous samples
