Accurate Temperature Measurement With Cropico 3000 Series

The Cropico 3000 series features three units, all with one milli-Kelvin resolution for RTDs (Real Time Displays).

This advanced product series 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.

The 3000 series temperature indicators form part of wide range of Cropico precision measurement instrumentation available from the Seaward Group
