These fourth generation Ex nA and Ex tc 4/20mA loop powered indicators have large high contrast displays with a very wide viewing angle. Operating over an extended temperature range they contain many standard features previously only available as options. Extensive thermal, impact and vibration testing provides maximum reliability supported by a three year guarantee.
No additional charge is made for factory calibration or for scale card or escutcheon marking, although the indicators can easily be recalibrated on-site.
