Cropico 3000 Temperature Measurement

Cropico Temperature Measurement Devices

A range of portable, high-accuracy digital temperature indicators which offer improved standards of measurement flexibility is now available from Cropico, the specialist supplier of precision measurement equipment.

The 3000 series features three units, all with one milli-Kelvin resolution for RTDs (Real Time Displays). Product has been designed for precision temperature measurement in a wide range of electronics, industrial, scientific and environmental monitoring applications, and comes with a choice of inputs for platinum resistance thermometers and all popular thermocouple types.

The 3000 has inputs for Pt25 and Pt100 platinum resistance thermometers and thermocouple. The 3001 offers the same flexibility as the 3000 but does not include the PT25 input option, while the 3002 is designed for use with Pt 100 platinum resistance thermometers only. Dual channel input allows the comparison and cross calibration of probes and sensor types and a variety of linearisation standards can be selected including user coefficients. Special features include the ability to eliminate thermal EMF and self heating errors along with the provision to store the calibration data of up to 20 PRT probes. An internal data memory facility can store up to 4,000 temperature readings for display or direct transmission to a PC or printer.

Statistical analysis of stored data can also be undertaken to provide mean, max, min, peak and standard deviation information. Fully portable with built-in rechargeable batteries providing some 14hr operating time and enclosed in a rugged aluminium case, the 3000 temperature measurement instrument has an accuracy of 0.01°C and resolution of 0.001°C, with SPRT (ITS-90) conversion as standard. The unit can also be supplied with an optional 19” rack mounting kit to allow the unit to be fitted into any standard enclosure for full system integration. To help with this, the unit has options of RS232 or IEEE for communications. An optional scanner can also expand the instrument to have up to 10 input channels for multi point temperature measurements. The scanner option allows the user to mix different types of scanner cards, to give the 10 input channels.

The user can have 4 PT inputs and 4 TC inputs, with the capability to incorporate all common thermocouples from B through to T.

International Practical Temperature Scale

In 1990 the international practical temperature scale was revised with a very small shift in the definition of the scale reference point from the freezing point of water, as used in the previous 1968 scale, to the triple point of water.

A digital thermometer is an essential tool for measuring temperature.

The triple point of water is the single combination of pressure and temperature at which pure water, pure ice, and pure water vapour can coexist in a stable equilibrium. This occurs at exactly 273.1598 K (0.0098 °C) and a pressure of 611.73 Pascals (ca. 6.1173 millibars,
0.0060373057 atm ) a difference of 0.01°C in the 1990 scale ITS90.

With the introduction of the ITS90 scales the previously called Degrees Kelvin” became Kelvin. The ITS90 scale has been adopted
internationally and supersedes the previous International Practical Temperature Scale of 1968.

Temperature Scales Comparison

There are three temperature scales in use today.

These are used for
