What our customers say...

Thanks for the suggestion. I finally retired my worn out U tube manometer. What a difference! This meter is my new best friend. The built in magnet is a great idea. I stick it to the cabinet and make my adjustments. Ne need to hold the meter with the extra hand I don't have to spare. I just ordered the EM201 so I can have the additional port.
