C-2000 Cotton Moisture Meter

11001-1356-200511

Tests made on seed cotton may not be as accurate as those made on lint

cotton. This is due to the fact that the seed cotton sample is obviously made

up of lint and seed, and the quantity of seed may vary from sample to

sample. Also, the moisture content of the seed is usually higher than that of

the lint.

When testing seed cotton, direct contact is still made with the cotton fiber

only and not with the seed of the sample. Variables in quantities and

moisture content of the seed, during calibration and in field tests, may affect

the accuracy and repeatability of the meter readings. The seed cotton scale

gives an indication of total moisture content (the moisture content of the

seed and the lint in a sample as determined by oven tests) in the seed

cotton sample. This may be of interest only in buying and selling seed

cotton where some consideration may be given to the weight relationship

between moisture content and dry matter.

TESTING BALED COTTON

Slide the plastic spacer over the 467912010 contact pins from the bottom of

the pins. Mount the pins in the chucks and tighten the set screws. (The

467912010 contact pins are not inserted into the chucks for shipping

purposes.)

Attach the Type 467912010 Electrode to the connector on top of the meter.

Set the scale to LINT COTTON and select a set-point. Insert the electrode

pins into the bale and press the Read button. Place the pin spacers near

the tips of the pins when contact is first made with the bale. This helps to

keep the pins parallel as they are forced into the bale.

The 467912010 contact pins are insulated, except for 1-3/4" at the tip. The

insulation helps to identify the area of moisture, since the reading is

obtained from the tip of the pin. Keeping track of moisture readings as the

pins are pushed into the bale will give an idea of the uniformity of moisture

distribution in the bale. Higher moisture readings near the surface are an

indication that the cotton has been exposed to higher moisture after baling.

The Dj C-2000 provides accurate results on normally compressed bales. If

the bale is loosely packed, the meter will read lower than the actual

moisture content. If the bale is very tightly packed, the readings will be only

slightly higher than normal, and as a rule, no correction needs to be made.

Well-conditioned material will provide uniform readings. However, material

that is baled before it is dry will show a wide range of moisture content.

Several tests should be performed on each bale, and the average and

highest readings should be noted.

TESTING YARN

Connect the 467912020 Multi-Pin Electrode to the connector on top of the

meter. Set the scale to LINT COTTON and select a set-point. Insert the

electrode pins into the yarn and press the Read button.
