A manometer icon
For medic sites, it won't be a good solution.
Yeah, which I why I said it may not get the point across.
If you could get an example that would be great. :+1:
I feel this might be too niche for this icon pack. We cannot add every measurement device.
For reference, this is a manometer
The manometer comes in all styles and shapes, for example.
A hand held manometer is very similar to other devices that measure something. So you could just have a generic "hand held device for measuring x" icon. This would cover things like measuring decibels, frequency, temperature, light, voltage, current, resistance, etc. For example: https://www.jaycar.us/multifunction-environment-meter-with-dmm/p/QM1594.
This would be good because a gauge icon does not convey performing a measurement via a hand held device. To use it in such a context would be confusing imho.
Maybe something along the lines of the following (48px):

Maybe with rounded edges would be more appropriate, but I find any angled lines are always difficult to get pixel perfect at 48 and under.

I'm currently on mobile, but why not just a rounded black vertical rectangle, a 2px white line across the top, and a white circle with a line signifying the dial at the bottom? We could name it gauge-variant.
Oh, scratch that, what about gauge-handheld and gauge-vertical?
So something like the following?

Looks a tad like an iPod to my mind, but maybe that's just cause I'm old ;-)
Oh and someone told me that it looks like a radio (speaker at base and gauge at the top for selecting the station, this is from someone a tad younger than me, but also old, so used to radios).
Hmm. Wasn't sure what you meant, so created a few:

Filled with rounded screen

Filled with lines to represent screen

Filled with cutout screen
Actually, not at all. Those look much more like Windows 10 icons than Material Design, and don't follow the MD specifications. Here's my rendition:


Also yeah looks like a radio
I like your approach, but not sure about the analogue indicator. Maybe remove the indicator and it will look good. The widths look a tad odd to my eyes, but maybe it's the square corners inside he rounded corners creating that effect. Need to get someone to look at it without context, as it still looks a tad like a transistor radio (I don't think there is any way to resolve that).
Did a new variant, very similar to yours. Main diff is the inside curve on the "lcd screen" part and I've simplified the dial.
