logo-pressure-gaugeDid you know that we can personalize our MILJOCO pressure gauges with your company logo and phone number? If you have a service division, a contracting division or both, pre-purchase your most commonly used ranges customized with your company logo and stock them on your shelf for use throughout the year. Why? So, they remember you and call you when they have service needs.

Great Brand Exposure + More Service Work.

Why do all of the work on a project, and simply “hope” that the customer calls you when he needs service work, rather than calling a competitor? With your logo and phone number on the pressure gauges, your company will be the first one your customer calls when additional work is needed.

How it works.

Here’s how you do it. For a one-time fee of $200.00, we will take your camera-ready artwork and create a master template. You must order at least 50 of each face that you need. When you run out and need to reorder, you pay only the price of the gauge itself!

You can’t beat it, it’s the best deal in town, and you’re advertising your own company instead of the gauge manufacturer. Call us at 800-355-7061 if you’d like more information, and don’t forget, MILJOCO is the only U.S.A. made pressure gauge!
