Page 5: Section 1 Product Overview
Section 1 Product overview The Intellical PHC281 series pH probes are digital, combination electrodes that measure the pH of water samples. The probes are refillable and have a built-in temperature sensor. The probes have good performance in low ionic strength (LIS) samples (e.g., deionized, reverse osmosis, distilled) and other clean waters (specific conductance less than 100 µS/cm to ultrapure). -
