Netdoc (or anyone who wants a "Magnehelic" Gauge),
I ordered the 2310 (5-0-5 in-h20) which appears to be the standard for checking 2nd Stage cracking and exhalation pressure.
To see prices, you need an account number.
Here's the long way to get a "temporary" account number:
From the Dwyer Home Page:
Click on <View Catalog>
Click on <If You Wish Pricing>
Click on <Click Here to Enter On-line Catalog>
You are now on the Catalog Login Page. At the bottom of the page it says:
*Note: To Obtain a Temporary Account Number to view products with pricing,
call Dwyer at 1-800-872-9141 or
email us with your name and address.
The Easy Way is to click the email link I just provided, and ask for a temporary account number (include your name and address). I got the account number e-mailed to me in about 5 minutes (on a business day). I went back to the "Catalog Login Page", typed in my name and account number, went looking for the Magnehelic "5-0-5", added it to my shopping cart, and spent $61.50 plus S&H.
