Model 3002
Precision Digital Thermometer with Pt100 inputs with CVD and ITS90 Coefficients
Quality Data and Value
The Series 3000 is a digital thermometer of very high accuracy (0.01 °C) and very high resolution (0.001 °C) at an economical price. To ensure that the very best measurements are achieved, PRT probe characteristics may be entered and stored using either CVd or ITS90 coefficients. The measuring current may be reduced by 0.707 to determine self-heating of the probe and may also be reversed automatically to optimise any thermal emf errors.
Convenient and Suitable for All Applications
The Series 3000 comes with many options. 2 channel inputs which enable you to compare thermocouples directly against a standard PRT (platinum resistance thermometers). This is ideal for those wishing to calibrate thermocouples. It also lets you measure or calibrate any mix of probe types (Pt100/Thermocouple, RTD/RTD, Thermocouple / Thermocouple) and display A, B or A-B on a large LCD Graphics Panel (240x64 Dot, LED back light contrast control via keyboard). The Series 3000 is linearised for 13 thermocouples Pt25 and Pt100: the choice of which to display is yours.
Full Instrument Control
The Series 3000 can be incorporated into automated measuring systems thanks to the RS232/IEEE-488 optional interfaces.
Statistical Analysis
The Series 3000 provides a maths functions to enable the statistical analysis of stored or filtered values to be displayed (mean, max/min, peak values, standard deviations). You do not need a separate data logger. The display may also be set to display the rolling average value and standard deviation.

*Apply to readings above 600 C.
The above figures apply to values with the Reference Junction switched off.
Reference Junction uncertainty when used in automatic mode is better than 0.1 °C at +20 °C with a deviation of not more than 0.01 °C/ °C over the range 0 to 100 °C.
