Product Information

A Microwave meter for rapid determination of moisture content in sand and other fine and coarse aggregates.

The Aggrameter® T-T-100 utilizes the latest microwave and microprocessor technology to measure moisture content in various fine and coarse-grained materials. The prongs of the probe are inserted into the material to be tested and the percentage of moisture content is instantaneously shown on the easy to read display.

An average of five to ten readings is normally taken in order to ensure a valid result. This output is converted by the integrated microprocessor and the moisture content is displayed directly as a percentage of dry weight. The Aggrameter® comes calibrated for both sand and aggregate, and can be programmed by the user with up to ten different materials. The maximum aggregate particle size to be tested is approximately 3/8" (or 9.5 mm) in diameter.

The Aggrameter® can store more than 150 readings - complete with time and date for future reference. Data can be recalled via USB interface to a personal computer.


The Aggralinx® software will allow connection of the instrument to a Windows 7, 8 or 10 personal computer. All the data stored by the unit can be uploaded to the personal computer for inclusion in quality control reports or any other form for later analysis. The software will also allow the user to ‘customize’ the Aggrameter® to a specific material. This will dramatically increase the accuracy of the unit.

Calibration Procedures

  • Dry sample in low heat using oven. It is suggested to weight sample prior to drying.
  • When sample has lost all moisture, calibration can be started.
    Weight dried sample
  • Add water by 2 percent increments.
    i.e. 4,000 grams – 2 percent water = 80 grams of water
  • Turn T-T-100 on
  • Using up or down arrows, scroll through the menu selection until Direct mode appears on the T-90 display. (It is recommended to erase all prior data saved in the T-T-100. (T-T-100 manual page 11))
  • Take 10 readings for each percentage. Store each reading by pressing enter.
  • After T-T-100 has hit full saturation (direct reading 409.5 percent), uploading data to C. Software is necessary.
  • Uploading can be done by connecting the Trident™ to the P.C. using the supplied RS232 cable.
  • Use instructions in the T-T-100 manual pages 14-17 to successfully accomplish calibration.
  • Once analyzation has been completed with the T-T-100 P.C. Software, the Offset and the Gain will be displayed.
    Write down these two values.
  • Return to the T-90 and enter a user program. (T-T-100 manual page 7 “Change user program”)
    Once the gain and offset have been enterd in the T-T-100, calibration has been completed.
