JRM has a good name in the market in manufacturing all types of thermometers ranging from Thermal power industry thermometers, steel industry thermometers, High precision thermometers, metal encased thermometer, Liquid in glass thermometers, electric contact thermometers. They also have reputed name as the largest laboratory thermometer exporters
Thermometer / Thermocouple Calibration:-
The definition of calibration is the comparison of two instruments, one of which is the instrument-under-test and the other is the reference. Calibration may or may not necessarily involve adjustment of the temperature measuring instruments-under-test.
Therefore, calibration does not always involve adjustment. If your instrument can be adjusted, then by all means, do so. If not, you should be aware of (and record) the instrument's deviation from the reference and use this information to compensate for the deviation.
We once had a temperature indicator that couldn't be adjusted. When we calibrate it, we find out how much it deviated from our reference. For example, if it reads 35°C vs our reference of 37°C, we put a sign near the instrument that instructs the user to add 2°C to the display to get the correct temperature. Of course, I got rid of that instrument as soon as possible .
So, my advice is for you to calibrate the thermocouple and the transmitter/controller/indicator as a unit, just as several posters suggested .
Thermocouple calibration is useful if you need better accuracy than +/-1°C, doing so may give you +/-0.1°C accuracy.
Key Features of JRM Thermometers:-
Glass Stems & Bulbs –
All the Thermometers are made from the highest quality of Glass Capillary that is free from stone, strise and irregular bores.
Permanent Accuracy-
All the Thermometers are skillfully annealed & artificially aged before graduation to ensure permanent accuracy.
Safety Chamber—
All the Thermometers are provided with safety chambers for precaution against breakage in the case of over heating and to facilitate rejoining of mercury column in case of separation in transit or in use.
Fillings—
All the Thermometers are either filled with Triple Distilled Mercury, Red/Blue Coloured Thermometric Liquid or the new Bio-Degradable & Non-Toxic Liquid.
Pressure Filling—
The Thermometers are pressurised with Nitrogen gas above the column wherever necessary.
Graduations—
Thin clearly cut and deeply etched graduations and distinctive figures accurately placed are done by the most up to date Calibrating and Graduating Machines.
Calibration—
All the Thermometers are calibrated against Standard Platinum Resistance Thermometer having least count of 0.001C and various other High Precision Thermometers. These standard thermometers are periodically tested and calibrated by National Physical Laboratory, New- Delhi. Calibration is carried out in special baths, which are scientifically designed, electrically heated & thermostatically controlled.
Accuracy --
All the Thermometers are guaranteed to be accurate within the tolerances required when they leave our works & when tested under correct conditions
Lastly we would like to conclude, that JRM thermometer, the largest Industrial thermometer manufacturers and also finest and most prestigious laboratory thermometers manufacturers of
