CEA Instruments, Inc.
Tetra monitors from one to four gases with a single button that controls all functions. A backlit "at-a-glance" display provides simultaneous viewing of all gas readings, alarm conditions, and battery life. Two versions are available including a rechargeable unit using lithium-ion batteries for 12 hours' operation from one charge, and a version powered by three conventional AA alkaline batteries. For testing confined spaces prior to entry, Tetra can be specified with an optional built-in electric sampling pump or used with a separate manual aspirator. Alarm tones are adjustable to ensure easy discrimination from noisy machinery. www.ceainstr.comInfo # 266 or www.IHadinfo.cc
