Lascar SP 400 Series 3.5 Digit LCD Panel Meters

Lascar Brand: Lascar

A range of 3.5 digit LCD panel mounting meters with backlighting for excellent readability in low light conditions. A negative rail generator enables the meters to measure signals that are referenced to their own power supply GND. The low cost and high performance of these units mean they are ideal for high and low volume applications in applications such as precision instrumentation systems, power supply monitoring, test boxes, panel mount indication, low power voltage/current measurement.

There are three meters available with either standard LED backlighting, blue LED backlighting or white LED backlighting on an enhanced black LCD background.

  • Digit height 9.75mm
  • Programmable decimal points
  • Auto-zero
  • Auto-polarity
  • Low battery warning
  • FSR May be scaled using resistors
  • Splash proof when mounted with supplied seal
