pHASE pH Electrodes provide accurate and stable pH measurement changes in dynamic process environments under wide ranging variable temperature conditions. The research-grade product is ideal for quality control and R&D use in a variety of applications. The product is available in two designs to best suit user needs: a user-friendly sealed design and the Rapid-Renew refillable design. The product is offered with either epoxy or glass body. The unit is a combination type with built-in double junction references, preventing the silver ions from contacting product samples. The products are stable to 0.01 pH within 30 seconds when exposed to a temperature change of 35-75Â°C. They are accurate to 0.04 pH at a temperature range of 0-100Â°C. The units offer 0.005 pH or less drift per 24 hours.
