Review on PIC PRO 201L 254P Industrial Stainless Internals by Leslie Matlak

Not a bad meter for the price. I'd love to see someone one day develop a glycerin-filled pressure gauge where the bubble doesn't interfere with the reading on the dial. Why? Why does the bubble have to be right in the middle of the pressure range I need? Yes, yes, I know there has to be some air for the gauge to work properly. However, I added some glycerine to reduce the bubble a bit. It still works accurately, but now it just covers the scale a little. Would it be so difficult to embed a tiny bubble reservoir to keep the sensor surface clean?
