Portable, Battery-Operated Fieldmeter for Performing Static Surveys
Advanced Energy’s 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.
- Ranges: ±2 kV/cm and ±20 kV/cm
- Sensitivity: 1 V/m and 10 V/m, respectively
- Static Accuracy: Better than 5% of reading
- Noise: <10 V/m rms, 0 to 200 Hz referred to input
- Response Speed: 250 ms 10 to 90% (typical)
Overview
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.
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
