Product details
These fourth generation intrinsically safe 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 and vibration testing provides maximum reliability supported by a three year guarantee.

No additional charge is made for factory calibration or for scale and tag marking, although the indicators can easily be recalibrated on-site.
