Automatic Aggregate Soundness Tester by use of Sodium Sulfate
Contents of page
Outline of Product Technology
Product number: MIT-658-3-24
This testing machine is designed for improved efficiency in performing laboratory tests, which is based on JIS A 1122 "Method of test for soundness of aggregates by use of sodium sulfate".
The testing process requires long time: [immersing -> filtering ->drying -> cooling x 5 cycles = 120 hours]. In existing methods, the testing schedule must be considered or the testing operations need to be stopped on holidays.
This machine enables nonstop testing operation even during holidays by its full automatic operation, once you make the operation settings. It does not cause uneven testing results depending on operators.
It is also space saving as all of the equipments for immersing, filtering, drying, and cooling are integrated into one unit.

Detailed Information
The testing chamber is structured with three vertical layers, and easy operation
The "immersing chamber", "filter", "dryer", and "cooling chamber" that have been conventionally placed on flat locations and processed separately are integrated and placed vertically in one unit, realizing automated cycle testing.
As compactly designed, it requires smaller space for installation and saves your space.
The operation panel is simply designed and consists of only the power switch and touch panel, allowing easy operation in setting for test and other functions.

A touch panel that allows easy operation and test status checking
Simple touch panel operation to make the test settings makes the apparatus to perform the whole process up to the end automatically. Also the current testing process, temperature, time, and other information are visibly shown.
Double liquid chamber structure that prevents damage on the mechanical parts due to the solution
Double jacket chamber structure indirectly keeps the sodium sulfate solution temperature in 20 ℃.
It prevents the clogging up due to sodium sulfate condensation and keeps the mechanical parts from being damaged.

Specimen protection function in case the power supply is cut off
In case a power cut or abnormal operation interruption occurs during the immersing process, the lift automatically raises to protect the specimen.
When restored, the machine continues the cycle that has been stopped.
When restored, the machine continues the cycle that has been stopped.
"Self error detection" to deal with troubles
In case any trouble happens, the touch panel indicates the part in trouble, causes, and solutions, so that you can deal with the troubles quickly.
An electric leak is also checked and detected automatically, and indicated by the specific part.
