Drying oven

A drying oven can estimate several samples' moisture content at the same time

• It can determine the water content

of large sample volumes

• It has a simple procedure to perform

The drying time is very long

(hours)

• It can evaporate other soil's substances other than water

• Additional equipment needed, such as precise measuring scale, and sample containers

• The drying oven method requires

handling and calculation; therefore, it is prone to error

• Not portable

• Occupies relatively a large space in the Lab

Halogen moisture analyzer

• Quick measurement

• Portable

• The halogen moisture analyzer does not require any calculation, and

its sampling is simple; therefore, the possibility of errors decreases.

• The heating rate is fast; therefore, the halogen moisture analyzer can

quickly reach its maximum power

• The equipment is fully automated

• Needs a very small space

• It can evaporate other soil's substances other than water

• The maximum amount of soil the moisture analyzer is limited to the

specimen holder size
