Configured for your application
The sensors in the G750 may be configured to best match your industry’s needs.The S3 (smart sensor system) allows flexibility for the user to interchange sensors in the field.To alert the user to increasing hazards, the unit has up to three user adjustable alarm points..

Powerful datalogging
The G750 datalogging option provides storage capacity for more than 30 days of continuous operation.

Downloading is easily done through the PC serial port that includes user name, location, and a detailed report of exposure levels and alarms.

The user name and location can be edited with ease for your needs.

Maintenance and security
Maintenance will never be missed with a user-determined inspection overdue alarm. Fresh air auto zeroing and AutoCal® calibration make routine maintenance effortless with no potentiometers to adjust.

To prevent unauthorized changes to alarm values, a code must be used to enter advanced maintenance menus to make adjustments.
