Our companyABOUT COLONIAL INSTRUMENTS

Colonial Instruments, Inc. is a stocking wholesale distributor of pressure, temperature, level and flow instruments. We represent most of the major manufactures in the industry and can meet all of your needs for any brand.

What separates us from others in our industry is our service oriented approach and value added services. Often times we see our competition providing quotations with vague descriptions like “Gauge, 100psi, 4.5 1/4 NPT”.  We eliminate the need for guess work, by providing extremely detailed product descriptions on our quotes, so you can be clear what you’re getting. Furthermore, we regularly provide custom product assembly sketches and full submittal packages for our customers, cutting down on the amount of work they need to do, and giving them a visual representation of the final product.

We pride ourselves on providing you with outstanding service and strive to exceed your expectations. Like our motto says… We Go The Extra Mile, It’s Never Crowded!..
