Model 257D

Portable Electrostatic Fieldmeter by Monroe Electronics / Trek 

 

The model 257D is a portable, battery-operated fieldmeter for performing static surveys or for use as a diagnostic tool when troubleshooting problems caused by static buildup.

  • Two switch-selectable measurement ranges (2 kV/cm and 20 kV/cm)
  • Recorder output to pass measurements to auxiliary instruments to display or record the data
  • Intrinsically safe sensors are approved for use in hazardous locations when used with approved IS barriers
  • Remote sensors can be located up to 1000 feet from the monitor
  • Chopper-stabilized measurement technique is drift free, even in ionized environments
  • An AC adaptor is provided to recharge the batteries and to operate the Model 257D during longer-term tests
Feature 1: Two ranges:  +or- 2kV / cm and +or- 20kV / cm
Feature 2: Remote probe for easy monitoring of hard to reach locations
Feature 3: Battery or line operation – AC power module included

Wherever you need NON-Contact Static Measurement:

  • Monitor charge buildup on webs during lamination, coating, manufacturing and printing
  • Check bonding during bagging, dumping, and transport operations
  • Static surveys in offices, on productions lines, “static-free” workstations
  • Prevention of dendric discharge patterns on photographic and X-ray film
  • Loop control for consistency in electrostatic backing of materials
  • Monitor static levels in textile manufacturing to prevent shocks to personnel, bunching and flying of product
  • Drift-free measurement ionized environments

The Model 1036F is smaller and lighter for
ease of use in less severe environments.
Both types have built-in provisions for
purging with filtered air or inert gas to prevent
drift and to provide additional safety in
hazardous areas. (Both Model 1036 sensors are
approved by Factory Mutual for use in
hazardous locations. See Specifications for
details.) Gas flow in the smaller Model 1036F is
through the sensitive aperture only. To ensure
thorough purging in the larger Model 1036E, gas
flow is directed across the face of the probe, as
well.
