The optional dual-mode combustible gas sensor provides 0-10% LEL readings as well as 1-100% by volume range when operated in the "TC" (thermal conductivity) mode.

Other features include easy-to-change, externally accessible battery packs, internal vibrator alarm, and a more water-resistant case design. The rechargeable, lithium-ion battery pack provides up to 18 hours of continuous operation. Design includes datalogging storage capacity for downloading to PC compatible computers with Windows 95, 98, 2000, NT, ME and XP.
