Cropico 3000 is the most comprehensive in a family of three precision digital thermometers. It features 1 millikelvin resolution for RTDs, with a range of standard features and a list of "mix-and-match" options which will provide a very high degree of flexibility.

The unit can be used by Quality Assurance departments throughout the process industries for calibrating temperature probes, particularly in ISO-9000 applications, it is also suitable for wide-ranging applications where high accuracy temperature measurements are 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 analog output, via a BNC socket, is another option. The 3000 series include a built-in data logger which can store up to 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 offers ease of use, password protected digital calibration and a large clear backlit LCD graphics panel ensure the 3000 is easy to use.

The 3000 has the ability to take reverse measurements, switching polarity then computing the average to eliminate source errors, this reduces thermal E.M.F. a capability lacking in most other resistance thermometers. Oftentimes 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.
