The MultiRae Gas Detector external battery charger allows a MultiRae battery to be charged while it is not housed in the unit. This is ideal for anyone who runs their MultiRae’s 24/7 or on back to back shifts. Now a back up battery can be swapped in without subjecting the instrument to down time. This is a must have accessory. The external battery charger comes as a stand alone unit and requires a power power. An additional accessory is available to group 5 battery charges on a single plastic holder, all of which can be charged simultaneously using a spider charger.

The MultiColor boots for MultiRae allow for customization of the look of MultiRae units. This is especially convenient for customers who operate with several different configurations of MultiRaes. Instead of using labels, or other ways to differentiate MultiRaes, they can assign each instrument a color so that they ensure the right instrument is selected for a given task.
