The PH100 is a waterproof ExStik® pH meter designed for fast and easy measurements. It features a flat surface electrode that measures a pH range of 0.00 to 14.00 with an accuracy of ±0.01pH, and it simultaneously displays temperature from -5 to 90°C (23 to 194°F). Key features include automatic temperature compensation, memory for 15 readings, a CAL alert for recalibration, and a RENEW indicator for electrode replacement. Its IP57-rated waterproof housing floats and protects the meter in wet environments, making it ideal for field or lab use across various sample types.
