Dwyer Instruments almost always has gauges and meters that we need in stock. The quality is reliably high. The technical support is always excellent.

Hi Matthew, and thank you for your kind words! I'll pass your review along to our technical support team as well. They work hard to give high quality support for all of our customers.
If your company wants to deals only with the Walmarts of industrial supplies then one day one of those Walmarts are going to go out of business for one reason or another--then you'll be looking for the small distributors that were loyal to you for years wondering how you are going to distribute your products. Not intereested in being a distributor for other distributors --NO THANK YOU !!!

Hi Edward! Thank you for your review and your long standing business relationship with Dwyer. While we do not disclose our discount structure, we do require an amount of qualifying purchases in order to participate in the program. We suggest reaching out to a distributor of Dwyer products for assistance.
Provide quality equipment. Typically always on time. What else can you ask for?

Hi Pat, thank you for your review!
Product is great, although I had a long look finding your A6 pressure switches...I'll be using this as a retrofit automotive fuel injection low pressure warning light pilot. For me the payment part was really clunky, so much so that I thought about just quitting after three tries at the credit card tab.

Hi John, thank you for your review!
Dwyer did not automatically provide an updated invoice, including shipping charges, for my on-line credit card purchase. Subsequently, I had to contact Dwyer by phone to have them email me an updated invoice, which is needed for my monthly accrual process. 16-Apr-21; Dwyer Customer Service called and explained that they are upgrading and modifying their web page and the issue of sending out updated invoices will be addressed in the near future. Thank you.

The web page doesn't allow you to view the product specifications even though there are tabs to select for more information. You must go to the digital catalog to get more information.
