This new moisture analyzer is considered to be less expensive, just as quick to produce a result, and as precise as comparable heat and weigh or microwave technique-based testers. The patented method of the HydroTracer is capable of defining the absolute water content where the mass of the water is measured within the reactor.
The sample is weighed and then filled into the HydroTracer’s sample tray, which is then positioned in the tester’s heating chamber. The sample is warmed by the heater to a temperature chosen by the operator, and water inside the sample evaporates. The heating chamber is attached with the cooled upper reactor chamber of the HydroTracer – this is the place where the calcium hydride reagent is placed. The volatile water now rises to the upper reactor chamber and the gaseous water reacts with calcium hydride when the humid air passes over the reagent.
The cooled, dry air then returns to the lower heating chamber and the process goes on. Air circulation via the HydroTracer is supported by natural convection, which is encouraged by the exclusive design of the HydroTracer; even hygroscopic materials are totally dried with the help of the analyzer. The ultimate concentration of hydrogen in the reactor is found to be proportional to the water content of the sample prior to the measurement. PC-based software controls the complete operation process and the results are calculated for the operator.
Principle of Operation
- Sensors measure the concentration of hydrogen gas
- Sample in removable heating tray
- Cooled, dry gas descends and can absorb more water vapor
- Hot humid gas rises into the reactor chamber
- Reagent absorbs water vapor and discharges hydrogen gas
- Carbon black
- Inorganic salts
- Calcium carbonate
