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.
