Overview

The Monroe 257D is a portable, battery-operated fieldmeter for performing static surveys or for use as a diagnostic tool when troubleshooting problems caused by static build-up. The instrument offers a chopper-stabilized measurement technique that is drift-free, even in ionized environments. An AC adapter is provided to recharge the batteries and to operate the Monroe 257D during longer-term tests.

Benefits

  • Use the remote probe for easy monitoring of hard-to-reach locations (up to 1000 ft)
  • Utilize the recorder output for unattended monitoring
  • Select either battery or line operation (with AC power module included)
  • Measure drift-free with chopper stabilization in ionized environments

Features

  • Intrinsically safe sensors approved for use in hazardous locations with approved IS barriers
  • Unmatched accuracy, stability, and versatility
  • Loop control for consistency in electrostatic tacking of materials
  • Included AC adapter for recharging batteries or using during longer-term tests
