Jar Testers

(Showing 3 of 3)

Jar testing shows how a water sample responds to coagulants and flocculants before you commit to a full-scale treatment program. Thermal Scientific carries the Phipps & Bird PB-950 portable programmable jar tester, built for use in the lab or at the site, and our team can help you set up a testing workflow. Water treatment teams, including those handling produced water and flowback, rely on jar testing to dial in dosage.

Pair your jar tester with multi-parameter meters and environmental and regulatory testing equipment, explore field equipment, or visit the Phipps & Bird supplier page.
