the advantage is the thermometer records a daily maximum and minimum temperature for reference. the disadvantage is the thermometer must be reset each day.
to allow a reference to accurately answer persoal questions about you
0 to 100 i think
for temperatures, zero is an arbitrary reference point, depending on which scale is used. for celsius, zero is assigned the the temperature at which water freezes. so temperatures which are colder than this temperature will be negative values, and temperatures warmer will be positive values. fahrenheit uses a different reference point for zero, but similar principles apply.
celsius is in reference to temperature.
this is the freezing point of water, 0 oc.

if you have 2 then you are right. the freezing point of water and the boiling point of water are the 2 fixed points.
a thermistor is a temperature sensitive resistor - to measure temperature you must measure its resistance and convert that resistance to equivalent temperaturea thermocouple is a temperature sensitive voltage source(i.e. battery) - to measure temperature you must measure the voltage across it and a reference thermocouple at a known constant temperature connected in series with it and convert that voltage to equivalent temperaturenote: thermistors do not require reference thermistors, thermocouples do require reference thermocouples at a known constant temperature. thermocouples are more linear than thermistors, making them easier to read accurately. thermocouples are available that are far more sensitive to small changes in temperature than thermistors.
it needs to be calibrated against a blank solution so that measurements after it can use the blank solution's absorbance as a zero reference.
the standard temperature scales celsius and fahrenheit have reference points at the freezing and boiling points of water. the kelvin scale has a reference point of absolute zero.
the point at which water freezes and the point at which water boils.
the primary reference electrode is the hydrogen electrode, which is rather fiddly to work with. secondary references are chosen for their stability and their reliable potentials so others can be calibrated against them.
-459.67 f which is absolute zero and that is the temperature at which all molecular activity stops.
you need to know the temperature of the reference junction and the voltage difference between the reference and sensing junctions. first, you convert the reference temperature to a voltage using the reverse equation or table for your thermocouple type. then you sum that voltage with the measured voltage. finally, you convert the summed voltage back to a temperature using the equation or table for the thermocouple type you are using. if the reference junction is at zero degrees c, you can skip the reference summing part. before computer processing was easy and cheap, the reference junction was often kept in an ice water bath for that reason.
when an author quotes another author, it is typically considered as using a "source" or a "reference." when you don't cite your source/reference accurately or not at all, it's called "plagiarism."
"since the emf generated by thermocouple circuits is a function of the difference in temperatures between the measuring junction and the reference junction, it is important that the reference junction be maintained at a constant, known temperature. this can be accomplished by (1) a temperature controlled oven, (2) an ice bath, or (3) an electrical means of simulating a known temperature."reference quote from national plastic heater (http://www.nphheaters.com/technical/thermo_letter.htm)
it is an slandered temperature that has been taken as reference. no system has this temperature some exception are there for perpection systems.
they calibrate instruments using known reference points. for example a thermometer is calibrated against a known reference point such as the freezing point of water 0 degrees centigrade or 32 degrees fahrenheit. assuming you are at sea level and the water has no contaminants which will cause a shift in freezing point. conversely the boiling point of water is 100 degrees centigrade at 212 fahrenheit. again ,pure water and at sea level because atmospheric pressure affects the boiling point.
0 and 100. they are used for the use of temp. the higher the number, the colder the substance/object is.
it certainly is necessary. sometimes it may be implied - for example, in practice, quite often planet earth is used as a frame of reference. but whether it is implied, or explicitly stated, you always need a frame of reference to describe motion, or position.
the patient is awake and talking and knows there surroundings. patient knows who they are, where they are and can reference time accurately
