Impact of COVID-19 on pH Sensors Market
The COVID-19 pandemic severely impacted the pH sensors market in 2020 and 2021. With lockdowns imposed worldwide, production activities were disrupted. This led to shortage in supply of critical components used in manufacturing pH sensors. Moreover, demand from end-use industries such as food processing, pharmaceutical declined significantly due to reduced operations. However, demand increased from the healthcare sector for monitoring pH levels in disinfectants and sanitizers used for prevention of virus spread. With rising cases, pH sensors were used in testing wastewater for traces of SARS-CoV-2 virus.

As lockdowns eased from late 2021, production and supply chain activities resumed gradually. Meanwhile, demand started reviving from food and beverage industry as food processing plants reopened with strict safety protocols. The pharmaceutical industry also boosted usage of pH sensors for research and development of COVID-19 vaccines and drugs. Going forward, the market is expected to grow at a steady pace. Automation in industries will drive integration of digital pH sensors for remote monitoring. Rising health consciousness post-pandemic is prompting use of pH sensors in consumer products to ensure safety. Continuous innovations to make sensors compact with improved accuracy will further support market expansion.
