ORTABLE HIGH ACCURACY TEMPERATURE INDICATOR WITH FULL INSTRUMENT CONTROLS, PT25, PT100 AND 13 THERMOCOUPLE TYPES

Cropico has produced a family of precision digital thermometers, the series 3000. Three units, all with 1 Millikelvin resolution for RTDs, are offered with a range of standard features and a list of "mix-and-match" options which will provide a very high degree of flexibility.

The units can be used by Quality Assurance departments throughout the process industries for calibrating temperature probes, particularly in ISO-9000 applications, and they also have wide-ranging use where high accuracy temperature measurement is essential and where values have to be stored for data processing.

Two-channel input provides A, B or A-B measurement on an LCD display, and front panel keys are provided for the most commonly used functions. Pull-down menus provide further functions, such as the selection of thermocouples. Probe characteristics can be stored for optimum accuracy, and the measuring current can be reduced by half power to check the probe's self heating.

Other features include mains or rechargeable battery operation, with built-in charger, and two interface options - RS232 and IEEE-488 - by plug-in cards. An analogue output, via a BNC socket, is another option.

The 3000 series include an inbuilt data logger which can store upto 4000 date and time stamped readings. Recall the data from the front panel or send to a PC via either RS232 or IEEE both of which are options.

The 3000 series offer ease of use. Password protected digital calibration and a large clear backlit LCD graphics panel ensure the 3000 series are easy for all levels to use.

The 3000 series have the ability to take reverse measurements switching the polarity then computing the average to eliminate the error source. This reduces the thermal E.M.F. which most resistance thermometers suffer from. The thermal E.M.F error can be greater than the quoted accuracy of an instrument. If you need small measurement uncertainy for high temperature PRT work, you need this feature.

Automatic Internal- Automatically references measurement to temperature of 20°C or other user defined temperature.User coefficients may be used
Automatic External- External Pt100 sensor temperature manual value can also be used

Hi / Low Limits

Limit values can be set over entire measurement range

Interfaces

Interface cards are available as option, only one card may be fitted. RS232: To specification ANSI/EIA/TIA/-232-E-1991 IEEE-488: Conforms to ANSI-IEEE Std 488, 1-1987 and performs the following functions: SH1, AH1,T5,TEO, L3, LEO, SR1, RL1, PPO, DT1, CO, E2. Interface may be set to ‘talk only’ mode to permit stand alone printer output
Scanner Option: 2 additional input cards may be fitted, each card has 4 measurement channels. Measurement and scan sequences may be configured from the front panel. Full accuracy is maintained

Thermocouples

The above readings 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. RTD types linearised to ITS-90 conforms to EN 60751. Thermocouples are not available on 3002 model

Scanner Options

The 3000 series scanner option provides for multi inputs of either thermocouples or Pt100 sensors. Two channel cards may be fitted each with four input channels, which may be either thermocouples or Pt100. The flexibility of the system is such that scanner cards can be interchanged giving 10 channels for Pt100, 10 channels for thermocouples, or 4 channels thermocouples plus 4 channels Pt100 plus the two front panel inputs, which may be either Pt100 or thermocouples. No other instrument in this price range gives the versatility and accuracy of measurement to match the 3000.
