How does your choice in manufacturers’ reps affect your bottom line?

When you start with the right process instrumentation, you get hardware that lasts for many years, enabling operational efficiency and low replacement costs.

Control Plus understands this, which is why we only sell the best – and we make sure our customers know exactly how to use it. For 25 years, we’ve helped engineers and plant managers squeeze every ounce of productivity out of their flow, level, pressure, and temperature instrumentation, making their job easier, saving them money, and – perhaps most important – delivering peace of mind.
