20/20SH Flame DetectorThe 20/20SH is designed to specifically detect invisible hydrogen flames. It utilizes our well proven triple IR design along with special sensors to provide the greatest degree of spectral matching to hydrogen flame emissions whilst being highly immune to false alarms. The 20/20SH can detect a 20" (0.5m) hydrogen flame at 100ft (30m) in less than 5 seconds.
