At what temperature is this hydrometer calibrated?

This Hydrometer is accurate when the temperature of the liquid is 60 degrees F. / 15.5 C. It comes with a chart in the container to adjust for higher or lower liquid temperatures to allow for adjustment.

I don't calibrate the meter. It works right out of the box for humidity level. I do not use the ph meter or the light meter. May be you can stick in in vinegar and see if it reads about 3

Hello Heather. I don't recall but I think it is 10 degrees. I don't pay much attention to it because when I used a thermometer, it was way off anyway. Water would boil at the 190 deg setting which if I remember High School physics correctly, we'd have to be near the top of Mount Everest for that to be possible. I control the temperature by setting the temperature I want then adjusting the power setting down to maintain it where I want it. Maybe it's just the unit I bought, but the temperature setting is nearly useless.

To calibrate any thermometer, you need to compare at least three of its readings (in the middle and at the ends of thermometer's temperature range) to the related readings of a standard one (the other thermometer with better accuracy). If you do not have another (more accurate) thermometer, the other simple way is to heat water to its boiling point (100 degrees Celcius) and measure this water temperature by Gogogu. Compare readings - you will know approximately what would be the error of your thermometer.

You can't specify a temperature. I believe it is pre-programmed to somewhere in the upper 70's. Unfortunately, with my 7 gallon nano tank, it was not capable of maintaining an acceptable temperature. I ended up replacing this.

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.

Never had a problem when the temp. was below 30degs.Lost my last one while ducking hunting, temp was around 30, water temp was cold, ice on surface in areas. I did not dive in after it, ordered another one.

Whatever flow you can put into it, it will measure as long as the fluid has a specific gravity of 1.0 (H2O), maximum PSI is 150 and the temperature is 105 degrees fahrenheit maximum.

Temp fluctuation when the probe is submerged is 1-2 degrees. It doesn't have anything attached to circ fluid but the response of the probe to change is quick and unless you need less than 1 degree accuracy I would recommend this gizmo.

To calibrate, use distilled water. You set the device to zero and thats all. You should do this once every three / four months.

FROM HM DIGITAL: The TDS-EZ was calibrated at 25 degrees Celsius (77F), but more importantly, the TDS-EZ is one of HM Digital's most basic meters and does not have Automatic Temperature Compensation (ATC). Therefore, since it does not have ATC, you will see discrepancies when testing hotter or colder from the baseline of 25C/77F.If your water is typically around this temperature, it won't be much of a difference, but if +/-10 degrees or more from 25C/77F, it's a good idea to get a meter with ATC, such as HM Digital's TDS-3, TDS-4, AP-1, COM-80 or COM-100.

I've used my Comark from around 60 degrees to temperatures around 350-360 (hot grease for fish). I've never used it to test below zero.

between 2 & 4 mm a second at 34 degree F and a fluid viscosity of 1 part over 16 parts at sea level .oh, I do not know, I have it hooked to the 3/4 inch main to warn me when there is a water cut off, it works.

I would be wary of the accuracy, there are "dead spots". I ordered two of these and both of them had a "dead zone" of about 6 degrees (from 76°F-82°F) where it would show it was 76° until it suddenly spiked to 82°.

It won't make water higher than 120. So < 120 is a good attempt to answer your question. If you are pre heating with solar, you prob. are limited to around that temp.

Yes. I put the probe tip in ice water and got the reading down as low as 35° F. Just don't get the entire probe wet or it will short out.

I've been running it in a 65 gal marine talk with a 10 gal refugium. I placed in the sump area of the refugium. It worked fine for me in a building that is climate controlled around 74-75 degrees. I found mine to be miscalibrated around 2.5 degrees, though, so you may want to consider an alternate thermometer if you have sensitive stock.
