King Instrument Company Operations Update

Dear Customers and Business Partners,

We are fully operational and do not anticipate any disruption to our capacity to deliver products. However, like everyone else, we are experiencing supply chain issues that may affect lead times of certain flowmeter models. 

Our top priority remains the health and safety of our employees, customers, vendors and all their families. We continue to follow the guidelines of the U.S. Department of Homeland Security for essential critical infrastructure workforce We thank you for your patience at this time and know that we will all get through this together.
