AutoRAE 2 MultiRAE Calibration Dock by RAE Systems Honeywell

AutoRAE 2 Cradle for pumped MultiRAE gas detectors

The AutoRAE 2 can bump testing and calibrate RAE Systems gas monitors. Versatile and modular, it can be deployed as a single, stand-alone unit to calibrate one instrument at a time, or networked to support up to 10 units at once and calibrate for up to five distinct gases.

MultiRAE Battery Charger by RAE Systems Honeywell

MutliRAE Battery Charger

The external battery charger accessory allows for the MultiRAE battery pack to be charged while it is not connected to the instrument. Up to 5 external battery chargers may be housed on the external charger holding tray.
