Laboratory Equipment
Manufacturer & Exporter of a wide range of products which include Laboratory Equipment such as Demonstration Board and Standard Programmable resistor.
Demonstration Boards
Item Code: DB-1
The DB-1 demonstration board is an indispensable element of training courses regarding realization of electric measurements. It may be applied in schools, distribution centers of meters used in the power industry as well as in training centers.

The board may be used for the purpose of simulation of the following measurements:

  • Measurement of the short circuit loop impedance in the L-N circuit for the TT and TN networks
  • Measurement of the short circuit loop impedance in the L-PE circuit for the TT and TN networks
  • Measurement of the parameters of the RCD switch type AC
  • Insulation resistance measurement in the L-N circuit
  • Insulation resistance measurement in the L-PE circuit
  • Measurement of the earth resistance by means of the technical method
  • Earth resistance measurement using clamps
  • Earth resistance measurement by means of the two-clamp method
  • Earth resistance measurements by means of the impulse method
  • Earth resistance measurements using meters for short-circuit loop measurements
  • Resistivity measurements of three kinds of ground
  • Measurement of the resistance of equipotential bondings
  • Measurement of alternating voltage
The demonstration board makes it possible to cause irregularities in the installation under scrutiny. This is possible thanks to the panel switches.

Programmable Resistors
Item Code: SRP-50k0-5T0
Index : WMGBSRP50K05T0

The SRP-50k0-5T0 calibrator is a source of high resistance, used as a standard in calibration and tests of analogue and digital insulation resistance meters.

The setted resistance by the calibrator can be maintained for a long time under external direct voltage up to 5000V, provided that the current in the measuring circuit does not exceed 3mA.

The required resistance is set by the user using the calibrator's touch keypad or via an external PC application. The required value is set automatically thanks to the switching of a precise resistance matrix. The controlling processor calculates the required combination of resistors, ensuring adequate resistance precision.

Standard Programmable Resistors
Item Code: SRP-50k0-100G0
Index : WMGBSRP50k0-100G0

The SRP-50k0-100G0 calibrator is a source of high resistance, used as a standard in calibration and tests of analogue and digital insulation resistance meters.

The setted resistance by the calibrator can be maintained for a long time under external direct voltage up to 2500V, provided that the current in the measuring circuit does not exceed 1,5mA.

The required resistance is set by the user using the calibrator's touch keypad or via an external PC application. The required value is set automatically thanks to the switching of a precise resistance matrix. The controlling processor calculates the required combination of resistors, ensuring adequate resistance precision.
