Does the temperature of the fluid effect the reading on the scale?

Not really. The calibration fluid (distilled water) and the test sample are supposed to be at the same temperature. For all practical purposes they will both be at the temperature of the refractometer since they are such small samples.

No, the temp would not change the scale as it measures the transparency of the fluid. Do it cold for convenience.

No it doesn't, but it has a tare weight feature where you can place an empty container on the scale and it resets to 0.0. Then as you add ingredients to the container, the scale only reads the weight of the ingredients.

The short answer is "yes." You simply put the measuring container (plate, cup, jar, whatever) on the scale and press the On/Off button. It immediately zeros the scale. You can then add the item to be weighed to the measuring container and the readout will display the weight of that item without having to subtract the weight of the container. Easy peasy! Apparently not everyone is aware of the tare function of this device -- hence some of the confusing answers.

Unfortunately - no. It is so accurate because it is so sensitive. You need to find a flat place to keep it permanently - although it can be reset whenever you move it. It seems like a drag, but the other wonderful aspects of this scale far outweigh this one inconvenience.

No, because it's range is from -40 to +302 degrees. I have checked it in ice water and boiling water and it is very accurate.

From my experience this is not a fixed value. If you set the flow switch at 0.5 GPM and the temperature at max, when you are flowing at a rate just above the 0.5 GPM you can a 90 Deg. F rise per the book. If you increase the flow rate above 0.5 Deg. F the temperature rise will decrease below 90 Deg. F. I have discovered that if I am using only the hot water and decrease the flow rate the temperature goes up. Note: 1 BUT will raise 1 pound of water 1 Deg. F; 1 gal = 8.34 pounds of water. Good luck with your unit, so times getting the proper balance between hot and cold water is a challenge.

Yes. For example, I put the plate on the scale then zero it out. If I remove the plate, the scale displays a negative number. I then repeat the process with each item I add--zero the current reading then add the next item. I hope this helps.

No, it reads the surface temperature of whatever object you point it at. You can't "point it" at clear air -- it will read the temperature of the surface across the room.

With regards to the question of measuring surface temperature of a pool or lake, and ice or boiling water, I have attempted some of those tasks with some success. Please note that the "emissivity" affects the accuracy of the reading. When trying to measure the temperature of boiling water, in a pot or saucepan, I got readings in the 95 - 100 degress C range. The steam that rises from the water affects the accuracy of the reading also, so a few attempts may be required. I have measured the temperature of a number of frozen objects in the home freezer, and I got reasonable values; values were about -15 to -20 degrees C, which is about what one expects. The depth of the liquid appears the affect the accuracy of the reading. The deeper the liquid, then the reading is more accurate. Measurement of oil temperature in an large open fat fryer gave me readings of about 170 - 180 degrees C, which compares well with other instrument results. The the instrument manual indicates the importance of the emissivity values of the object of which the temperature is to be measure, I have found that generally the instrument gave reasonable results "out of the box" without any emissivity value adjustments for a variety of surfaces. It is an excellent product for the price. Kind Regards, Dan D. 30-May-2015

I bought this as a gift and did plenty of research into the same question and the answer I found was yes, this prob should, according to the manufacturer, read two different temperatures at once.

I can not answer that but what I did was take it to the nurse where I work and compared their readings to mine using their equipment vs mine. The results were very close. The nurse was happy with the comparison. She said it is not an exact science.

most likely you'll get the glass surface temperature if the beamis focused on the glass surface. you'll need to sight down directly on the liquid to get a better sense of its temperature (and it'll be a near surface measurement, not of the bulk average.)

My understanding is that it takes the temperature at the surface of whatever it is you point it at. I use it to test the temp of my coffee in the morning so I don't burn my mouth (140 degrees or lower). You can even temp the pool! It works great!

Absolutely. There is a target temp that is set by the user and an actual temp. Very rarely does it fluctuate within .2 deg either way. Yes two tenths of a degree. Very accurate device.

I'm sorry, I have not experienced this. I have tried the scale on carpet and tile and I get the same reading. Have you tried moving the scale to different spots on the linoleum or hardwood floor and see if you get different readings? Myself, I would use the lowest reading and feel better about myself.

No..the scale is not a mathematical calculator..it will only show how much you put or take, but not the difference between amounts.
