Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision. They are made of metal or glass and strengthened through processes such as thermal tempering or annealing. Several types of laboratory thermometers are commonly available. Liquid-in-glass thermometers are made of sealed glass and contain a fluid, usually mercury or red alcohol, whose volume changes relative to its temperature. Bimetallic strip thermometers include two different metals that are bonded together and expand at different rates as they warm up. Often, long bimetallic strips are wound into a coil and used with a dial. Electronic devices such as thermistors measure changes in electrical resistance and convert them to changes in temperature. Infrared thermometers are non-contact devices that convert infrared (IR) energy to an electrical signal that can be displayed in units of temperature. Other specialized or proprietary products are also available.

Jrm Laboratory thermometer manufacturers india measure temperatures in degrees Fahrenheit (F) or degrees Celsius (C). Graduated scalar divisions or test points determine the accuracy with which users can read each type of device. Typically, display numbers are etched or printed on the thermometers housing. With some devices, permanent pigmentation of graduations is used to improve readability. Features such as clip-on magnifiers help users read numbers on more detailed scales. Some laboratory thermometers can be fully immersed in the media being measured. Others can withstand only partial immersion. Devices encapsulated with polytetrafluoroethylene (PTFE) are suitable for monitoring acids or other hazardous materials. Teflon, a registered trademark of DuPont, is a common, proprietary form of PTFE. Laboratory thermometers with a protective metal sheath and no-roll cap are commonly available.

Organizations such as the National Institute of Standards and Technology (NIST) and the American Society of Testing and Materials (ASTM) calibrate laboratory thermometers and provide traceability. NIST provides calibration services for a variety of laboratory thermometers that cover a temperature range from -196 C to 550 C (-321 F to 1022 F). Submitted devices must pass a preliminary examination for fineness and uniformity of graduation as well as freedom from moisture, gas bubbles, and cracks. The thermometers to be calibrated are placed in a constant temperature bath along with an NIST-calibrated standard platinum resistance thermometer that is traceable to the International Temperature Scale of 1990 . Special tests may also be conducted on industrial-grade platinum resistance thermometers, digital thermometers, and thermistors. ASTM-certified laboratory thermometers must also pass rigorous testing requirements.

Different types of thermometer manufactured by JRM Thermometers

A thermometer is simply a device to measure. Thermometer has two important factors, in which it sense the temperature the temperature of the element with a mercury bulb. And another one is thermometer changes this physical change into value which we see in a digital display.

Jrm thermometers manufactures custom made process control instruments like Programmable Process Indicators and Controllers, Programmable Sequential Timers, Loop Powered Indicators, Large Sized Digital Indicators, Square Root Extractors, Flow Totalizers, Scrolling Displays, Data Loggers, Process Scanners. e also deal in to Tailor made Electronic Instrumentation. Depending of the process requirements, requirements of user’s changes and those becomes specific, in certain cases. We design and develop the Instruments as per the client’s requirements. Those are mainly in to demand at Building Automation Systems, Dosing Systems, Batching Systems, Smoke Analysis etc. We also have a base in System Automations.

Thermometers not always makes perfect reading, it all depends on the accuracy, precision and reproducibility. Jrm thermometers match all the qualities as the best thermometer manufacturers of India. Some electronic thermometers or clinical thermometers can measure upto 0.1°C as these thermometers are calibrated to fixed point. If all the thermometers are calibrated from 0 and 100°C it becomes accurate in the sense that it will give the right temperature reading.

For many purposes reproducibility is important. That is, does the same thermometer give the same reading for the same temperature (or do replacement or multiple thermometers give the same reading)? Reproducible temperature measurement means that comparisons are valid in scientific experiments and industrial processes are consistent. Thus if the same type of thermometer is calibrated in the same way its readings will be valid even if it is slightly inaccurate compared to the absolute scale.

An example of a reference thermometer used to check others to industrial standards would be a platinum resistance thermometer with a digital display to 0.1°C (its precision) which has been calibrated at 5 points against national standards (-18, 0, 40, 70, 100°C) and which is certified to an accuracy of ±0.2°C.

There are a number of uses for thermometers. Thermometers have been built which utilize a range of physical effects to measure temperature. Temperature sensors are used in a wide variety of scientific and engineering applications, especially measurement systems. Temperature systems are primarily either electrical or mechanical, occasionally inseparable from the system which they control (as in the case of a mercury-in-glass thermometer). Alcohol thermometers, infrared thermometers, mercury-in-glass thermometers, recording thermometers, thermistors, and Six's thermometers are used outside in areas which are well-exposed to the elements at various levels of the Earth's atmosphere and within the Earth's oceans is necessary within the fields of meteorology and climatology. Airplanes use thermometers and hygrometers to determine if atmospheric icing conditions exist along their flight path, and these measurements are used to initialize weather forecast models. Jrm thermometers have been the largest thermometer exporters of all time.

Jrm Thermometer manufactures many types of Industrial thermometers like wall thermometer, soil thermometer, electric contact thermometer etc. This makes the Jrm thermometers the largest Industrial thermometer manufacturers.
