Edwards's Gascheck G3

Introduced as an enhanced replacement for the popular GasCheck 3000, the Gascheck G3 incorporates a new backlit dot matrix LCD for improving viewing in poor lighting and leak rate indication by both flashing LED and sounder, for easier use in all environments. In addition the GasCheck G3 has a new tactile keyboard with fewer keys and improved temperature stability for better performance in uncontrolled areas.
