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. Coated printed circuit boards plus extensive thermal, impact and vibration testing provides maximum reliability supported by a three year guarantee.

Both models can be supplied custom calibrated and labelled with scale and tag information free of charge.
