6554 Desiccant 1/6-Unit Bag

Overview

The 6554 Single 0.16-Unit Silica Desiccant bag desiccates the inside of some of our dataloggers. When shipped, the datalogger has one bag of this desiccant inside it. The supplied desiccant should fill the initial needs of most applications, but it should be periodically replaced. Campbell Scientific recommends replacing this desiccant when the datalogger's internal lithium battery is replaced.

What is a Unit of Desiccant?

A unit of desiccant is defined as "the amount of desiccant that will adsorb at least 3 g of water vapor at 20% relative humidity and at least 6 g of water at 40% relative humidity at 77°F (25°C)."

If you're really interested, MIL-D-3464E is the source document that outlines the generally accepted method for determining the units of desiccant required (calculation requires the size and the type of the container and the type of desiccant to be used).
