THE PRECISION COMPUTER COMPARATOR OF IMPEDANCES

The last word in the field of impedance measuring, the most unique system is intended for precision reproduction of units of characteristics of complex resistance, transfer of the values of units in a measurement range, and also for measurement of capacity C, inductance L, active resistance R, a tangent of angle of losses tg δ, a tangent of a phase corner tg φ, time constant τ during the process of metrological works on certification and checking of measures of characteristics of complex resistance, and also for exact measurement of these characteristics. The comparison error on R, L, C is less than 1x10^-7. The instrument has small dimensions and weight.

RLC-METER PRECISION ÌÍÑ1100

It is intended for automatic definition of parameters of an impedance (capacity C, inductance L, active resistance R, mutual inductance M, a tangent of angle of losses tg δ and a tangent of angle of phase shift tg φ (quality factor Q_C and Q_L)) on any of two-element equivalent circuits, and also percentage deviations with representation of results of measurements in a digital form. RLÑ-meter can be used for performance of metrological works, at the checking of electro and radio engineering products, in scientific researches, at measurements of not electric quantities with use of any type sensors.

RLÑ-meter provides: an automatic choice of character of reactance of object of measurements on the criterion "the prevailing parameter"; the account of initial parameters; averaging of results of measurements; elimination of influence of network interferences (on the separate stipulated frequencies); measurement with adjustment of value of ac voltage submitted on object of measurement; two modes of measurements: single - for measurement of unknown quantities; following - for continuous measurement of changing in time quantities; four-pair connection of object of measurement.

AUTOMATIC PRECISION òåRMOMETER ÑÀ320

This multichannel high-precision system is intended for measurement of following physical parameters in metrology: temperatures, humidity, pressure, deformation, small displacements, a magnetic induction, dc voltage. The system can work with two channels in an independent mode and over 512 channels in an operating mode from the personal computer. Thus, any type of the sensor (with output  parameter resistance, transfer coefficient or voltage) can be connect to each channel. The relative error of measurement is 2õ10^-5 for transfer coefficient or voltage or 5õ10^-5 for resistance. The instrument has small dimensions and weight (0,5 kg). Due to excellent characteristics the device is already successfully used in many metrological centers of Ukraine and CIS countries.
