美国采购需求：压力计

I'm reaching out to inquire about your pressure gauges. I'm specifically looking for gauges that can adjust from 0 to 5500 psi and feature an automatic shut-off function. It's important for us to know if these gauges allow for precise adjustments for specific psi readings, as we need flexibility for different applications. Additionally, I'd like to confirm whether these gauges have both low and high psi settings. Having clear options for different pressure ranges will be essential for our operations. Please provide any details you can on these features, as well as availability and pricing. Looking forward to your prompt response!
