The digital precision multimeters of series 8000 - these are the newest high-precision multimeters of the firms Transmille, which enlarge the rule of reference instruments for the needs of metrological service.

• Model 8081 - accuracy 0,00004% (4ppm)
• Model 8071 - accuracy 0,00009% (9ppm)

Multimeters of 8000 series this:

Clear, bright and familiar mapping of the measurements & of the parameters of tuning, using a dual fluorescent display - ideal for the readout of results even at the point of the distances;
Unique indication of terminals - intuitive operation with the light-emitting diode indication of terminals for the correct connection during the use;
[Ergonomichnaya] keyboard - complete control over functions and ranges of instrument, accessible based on the keyboard from the 3rd groups of buttons, and by the possibility of joint use together with the digital regulator, for the greater flexibility of the user control of functions, ranges and the additional parameters of tuning;
30[A] entrance (model 8081) - makes it possible to measure the currents for the sake of force to 30[A], without the use of current shunts. This is the highest value of current entrance at the point of the given moment, of all accessible at present precision multimeters. (10 A entrance for model 8071).
Weak-current entrance for the function of electrometer. This entrance proposes “virtual” grounded zero input impedance and high testing voltage (200 c), and so the performance characteristics of electrometer, integrated beside the precision multimeter.

• Programmed terminal of the switchings
  The remote control besides entrances on the front/rear panel, directly based on the computer or the indicator face, for the switching between the standard and the believed instrument.
• Intellectual function of the relative measurements
  Unique operating conditions makes it possible known standard to connect down the terminals on the rear side, and the believed instrument to the frontal terminals for the comparative measurements. The precision multimeters of 8000 series during the measurements make it possible automatically to be switched between the standard and the believed instrument, mapping onto the display of value based on the believed instrument as relation to the introduced value of standard (function of comparator)
• Measurement of temperature (8081)
  Precision measurement of temperature with the use of resistance thermometers. 8081 include the extended regime of storage of the constants of model resistance thermometers.
• Measurement of pressure (8081)
  With the aid of the developed modules of the pressure Of transmille, connected down the built-in interface, the multimeters of 8000 series can measure the pressure with the output of results to display.
• Measurement of light currents (0,1 pA - 10 A)
  The lower range of measurement DC of current (10 on), makes it possible to conduct measurements with the permission 0,1 pA, using the specialized screened entrance BNC of the type. This entrance proposes “virtual” grounded zero input impedance, integrated before the precision multimeter and making it possible to work to it before the regime of electrometer.
• Measurement of high resistances (8081)
  8081 make it possible to conduct the measurements of resistance to 1 Tom, using the weak-current specialized screened entrance BNC of the type (it is necessary for measuring the low-noise/high values of resistance). High testing voltage (200 c) together with auxiliary pA for the sake of entrance, ensures the measuring system of the resistance of high efficiency, which uses performance characteristics of the electrometer, whose functions are integrated beside the precision multimeter.
