This Atlas Scientific Lab Grade pH probe is our highest accuracy pH probe. The internal double junction lets you read the pH of protein-rich solutions without damaging the probe. The green Vanadium III tip is a hydrogen amplifier, reducing noise and increasing reading stability. A Tyvek™ junction connects the pH probe to the outside world. Because Tyvek™ resists water flow, the internal electrolyte is held in the probe longer, leading to less frequent recalibrations.
