The MonroeTM 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.
- 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
- 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
