Device PEP-02
Price by request

The compact portable electrical measuring device PEP-02 is designed to measure AC and DC voltage, current, electrical resistance, capacitance and inductance in intrinsically safe electrical circuits. The device has explosion protection marking PO Ex ia I Ma X and can be used in underground workings of coal mines, hazardous for gas (methane) and coal dust, at ambient temperatures from -15 to +50 ° С. Certificate No. TC RU C-RU.МГ07.В.00188 

The device can be used to measure electrical parameters of intrinsically safe circuits with parameters Ui: 100 V; Li: 7 A; Ci: 1μF; Li: 0mH.

Main functions:

  • Large display with white backlight; 
  • Data hold mode; 
  • Low voltage measurement - 400mV; 
  • Frequency measurement - up to 100 kHz; 
  • Capacitance measurement - up to 100μF; 
  • Temperature measurement function. 

To buy the PEP-02 Device, you need to contact the managers.
