The Miller 400A is perfect you, whether you need to measure soil resistivity or the resistance-to-earth of an electrode, such as ground rod or an anode.

Features
  • Rugged, lightweight case - safe to use on wet ground
  • Weatherproof, even with lid removed - IP67 rating for dust and water intrusion
  • Convenient case lid removal for ease of movement, with test leads attached, to new measurement locations
  • Resistance measurements are unaffected by any stray interference signals that may be present in the earth during readings, due to the use of narrow band-pass filters centered at 97Hz (the unit’s operating frequency)
  • Runs on a set of C-cell alkaline batteries...no need to periodically recharge the unit or to plug it into a power source
Specifications
  • Resistance measurement range from 0.01Ω to 1.1MΩ
  • Storage temperature range (with batteries installed): -30°C to 50°C (-22°F to 122°F)
  • Operating temperature range: 0°C to 54°C (32°F to 129°F)
  • Dimensions: 12" W x 10" L x 5" H (31cm x 25cm x 12.5cm)
  • Weight: 7 lbs (3.175kg)
