PROMAX PE-331
Earth Resistance Meter,
Discontinued

• Earth Voltage: 0 - 200 V AC, 40 ~ 500 Hz
• Earth Resistance: 0 - 20 W (res. 0.01 Ω), 0 - 200 W
  (res. 0.1 Ω), 0 - 2 kW (res. 1 Ω)
• Current: 2 mA
• Battery: 6 x 1.5 V

PROMAX PE-331's measurement current of 2 mA allows to take resistance ground tests without tripping the circuit breakers from circuit to verify. Among its functions we should point out: reading memory indication, overmargin indication, open circuit indication and auto power off.
