Founded in 1914, and now part of Clark-Reliance Corporation, Jacoby-Tarbox manufacturers sight flow indicators and sight windows to verify process conditions throughout piping, vessels and other equipment. All Jacoby-Tarbox sight flow indicators and sight windows with flat glass can be supplied with dual windows (for FM-approved assemblies) or with fused glass and metal UniGlas windows. Jacoby-Tarbox also produces a line of tank lights and sight flow indicator lights to improve visibility in dark processes or locations. Jacoby-Tarbox eductors and tank liquid agitators help customers improve the reliability of their in-tank mixing processes for product consistency and process uptime.
