The CA-21 is the ideal instrument for routine moisture analysis in the field or laboratory. It's a lightweight, compact instrument that can easily be converted to a portable unit by addition of the optional carrying case and rechargeable battery.

Simplicity : just press the start button, inject your sample, input sample data and read the result in ppm or % H2O

Portability : the above simplicity combined with the portability of the unit allows your to monitor moisture content in the field.
