Potential Drift Compensation Technology of pH Online Monitoring in Deep Aquifer
Journal Title: 河南科技大学学报（自然科学版） - Year 2018, Vol 39, Issue 6
Abstract
The long-time and online monitoring of p H was restricted by potential drift. The influence factors of potential drift were discussed in p H long-time and online monitoring, and the critical factors was confirmed.Based on the instrument zero drift intelligent compensation technology and p H electrode potential drift compensation technology, the p H in situ and on-line monitoring instrument of deep aquifer was developed. The measurement accuracy is in ± 0. 2 pH through indoor and outdoor application testing.
