Overview

The Monroe 288B is an easy-to-use, innovative high voltage electrometer that provides tests to unprecedented low voltage with unmatched stability. All test parameters are programmable, allowing tests to be optimized and not dictated by equipment limitations.

Once programmed, the Monroe 288B will perform a series of tests automatically: ± decays, balance, balance peaks, temperature, humidity, time/date are stored and may be reviewed via the display or downloaded to a PC. The included software permits the user to define and name ionizer locations, test setups, and sequences and upload them to the CPM. All of these features result in a flexible, easy-to-use instrument that facilitates audits while minimizing errors.

Benefits

  • Perform manual and automated testing of decay and balance
  • Store up to 1500 tests, 500 locations, and 4 test protocols
  • Use the large, easy-to-read, high contrast LCD display
  • Configure operating parameters
  • Utilize soft keys for highly intuitive programming

Features

  • Internal battery for portable operation
  • Detachable 6 x 6-inch plate with optional 1 x 1 in plate
  • Built-in temperature and humidity sensors
  • Auto-ranging to 0.1V resolution below 100V Meets ESD Association Standard ANSI / ESD STM 3.1
