Different types of Thermometers manufactured by JRM thermometers India

Thermometers can be divided into two separate groups depending on the physical basis of thermodynamic laws and quantities. But in the case of primary thermometers the temperature can be measured without any unknown quantities. These types of thermometers work based on state of gas, velocity of sound in gas.

Secondary thermometers are used because these are very convenient to use but these types of thermometers are much more sensitive than the primary ones. These thgermometers have to be calibrated against the primary thermometers to a certain temperature level or at fixed points of temperature. JRM are the largest Laboratory Thermometer Manufacturers of india.

Thermometers can be calibrated either by comparing them with other calibrated thermometers or by checking them against known fixed points on the temperature scale. The best known of these fixed points are the melting and boiling points of pure water. (Note that the boiling point of water varies with pressure, so this must be controlled.)

The traditional method of putting a scale on a liquid-in-glass or liquid-in-metal thermometer was in three stages:

Immerse the sensing portion in a stirred mixture of pure ice and water at 1 Standard atmosphere (101.325 kPa ; 760.0 mmHg) and mark the point indicated when it had come to thermal equilibrium.

Immerse the sensing portion in a steam bath at 1 Standard atmosphere (101.325 kPa ; 760.0 mmHg) and again mark the point indicated.

Divide the distance between these marks into equal portions according to the temperature scale being used.

These types of laboratory thermometers are manufactured by JRm thermometers and they are the largest laboratory thermometer exporters of india.

Bio-degradable Thermometer:

India’s First Mercury Free Thermometers Environmentally safe non toxic, Biodegradable Liquid. Accurate, Precise, Repeatable was manufactured by JRM thermometers. They are india’s first Bio-degradable thermometer manufacturers.

With SafeTherm we are working towards reducing the usage of mercury in scientific laboratories, classrooms, industries and in our society. Our aim is to provide alternative to mercury containing thermometers with environmentally safe, non-toxic, non-hazardous and biodegradable liquid filled thermometers.

SafeTherm thermometers are available in all typical range from – 20 °C up to 250 °C.

Minus Range Thremometer:

Minus Range Thermometer are liquid in glass thermometer with coloured spirit filled thermometers. The range of minus range thermometer is -50 - 100°C. This thermometer has a total length of 300 mm and the immersion length of minus range thermometer is 75 mm.

Metal Encased Glass Thermometers:

Metal Encased glass thermometers comes with yellow black or white one with liquid filled coloured spirit. Metal encased glass thermometers comes in a maximum range of 0- 600°C. And are available in sizes of 4//6/8 inches. And are mostly used in Ships, Diesel Engines, Pipe Lines, Tanks etc.

Thermometer - A temperature measuring instrument

Thermometer usually measuring tool to measure the hotness or coldness of a substance in a definite scale. The temperature can be read when the substance is brought into contact with the thermometer. This temperature measuring instrument use some change in material to indicate temperature. There are some effects to apply to these temperature measuring instrument , like change in physical properties and altered physical dimensions. One of the notable change that is noticed in these temperature measuring instrument is the change in the length of the material in form of expansion and contraction.

The most important element of a thermometer is the temperature sensor, i.e the bulb of the mercury thermometer.

.Usage of thermometer

There are number of usages for thermometers. Thermometer usually use different physical; effects to measure temperature of a particular substance. These type of temperature are used in engineering and scientific applications. Temperature controls are in separable in case of liquid in glass thermometers as these are either electrical or mechanical. Liquid-in-Glass Thermometer Manufacturers in India are best manufactured by JRM Thermometers. In the Earth’s atomosphere specially in the fields of meteorology and climatology glass thermometers, alcohol thermometers and infrared thermometers are well exposed in the atmosphere for different industrial needs. Indusrial thermometer exporters like JRM Thermometers make it possible with their utmost precision and accuracy level. Even airplanes use thermometers and hygrometers to measure if there is atmosphere icing along the flight path. Even thermometers are also used to predict weather forecasts. And in climate control systems like air –conditioners, freezers, refrigerators and water heaters thermistors are used.

Thermistors and infrared thermometers are also used during cooking meat , to now the mat is properly cooked or not, if the temperature remains constant for more than four hours or more between 5 °C and 57 °C , then the bacteria can multiply and can ruin the food. Thermometers are in candy manufacturing also. Mediacl Thermometer such as Liquid-in-Glass Thermometer, glass thermometer , pill thermometers and liquid crystal thermometers are used in health care sectors to measure fever. Liquid –in glass thermometers are also used to measure the temperature of fish water tanks , and JRM thermometers are the finest Glass Thermometer Manufacturers India and Liquid-in-Glass Thermometer Manufacturers India.

JRM thermometers the most trusted name in the market are the manufacturers of Industrial, laboratory, Glass Thermometer and also they are the largest exporters of thermometers from India.
