Will it measure readings below sea level, like in Death Valley?

if you zero it in death valley and then bring it up that it will show proper reading

It measures ground level zero wherever you press the lauch button, example,if you press the launch button on the ground it will calculate that as zero, if you press the launch button 3 feet off the ground it will calculate that as zero,i tried this, with a confirmed hight of 125 feet it was accurate at ground level and off 3 feet when launched at waist level,so I would say yes it should work fine

It does negative values. When you turn it on, it zeroesI've done that when at 1200', so it reads -1150 when I get home.So I assume it will.

I'm at 11 to 14 feet above sea level and it reads 0 until you hook it up and turn on the water. My municipality delivers our water rated to 60#psi related by the meter and two different households had readings of 60 and 62. If you live in the mountains and have a water supply rated to let's say 80#s then it would read out 80#s on this gauge as all things are relative.

I would ask if you are at high elevation, as per the canning books by Ball describe. I am at sea level but can get my gauge to go up and down as I need.

Will not detect well or at all in wet saltwater sand or in saltwater, as it is too conductive. Highly mineralized ground or "black sand" as they call it may also give it fits as it does most metal detectors. You can't ground balance the unit properly to stop it from chirping away or "falsing" under these conditions. See my recent review. Hope this helps.....

Yes.It is as sensitive as you want it to be.You can adjust the sensitivity so it detects very small and very distant earthquakes before the major shaking hits your house.It was so sensitive that when I was in Los Angeles I had to turn it way down.

Yes it can. Easily. There is a Celsius/Fahrenheit button to toggle between the two readings.

It did for us. We have used it to check soil temps for transplanting and direct seeding vegetables. I don't remember how far down we checked, but it was enough that the thermometer didn't fall over; so probably more than 1 -3 inches.

I agree with David, invest in a better tach for your application unless you're always close to shore. This (and similar items) is NOT a high quality precision product. It's a cheap solution to track non-critical service revs. Besides, I would highly doubt the readout would be bright enough on the water based on mine.

I do not think .. I'm used to measure distances only. I did not find anything in the device for the rise.

I really am not sure, if what you want to measure is very low pressure than I think it would work. This unit measures in water column and is very sensitive.

It should be pretty accurate with a shallow amount of oil. If the amount of oil is deep enough for a standard thermometer, use it to compare against the laser measurement.

I can only state that it gives very accurate readings right where you are holding it. For down range - I would think at least the wind could vary.

What the manual is saying if you calibrate this scale at say 100 ft above sea level and than use the scale at 10,000 ft above sea level you will need to recalibrate the scale.

No. It is definitely off by a hundred feet or 200 with each reading. My coworker and I are both fire fighter who bought the watch for elevation while doing weather on fires and from our GPS readings the elevation is approx. 100-200 ft off each time.

Yes, but be aware that it only measures temperature when you ask it to (from the app). It doesn't monitor conditions continuously.

Probably...the difficulty is going to be getting the sensor to be able to read something that is not static....but, will give you a general idea of the temperature, I think.

No. It only measures surface temps.On a side note, my unit broke within an hour of delivery. I would not recommend this product.
