Moisture Analysis

Fully automatic thermo-gravimetric analysis operating at temperatures of up to 1000°C. It determines moisture and ash values automatically and produces up to 80% savings in workload and costs. In one working cycle, up to 29 specimens and a reference pan are ashed fully automatically.

The prepASH provides higher precision and reproducibility of the results through considerable improvements of manual procedures. This is an instrument where no technology transfer data loss occurs and where the entire process is monitored and recorded from start to finish. In one working cycle, up to 29 specimens and a reference pan are ashed fully automatically in accordance with the latest quality guidelines, monitored and recorded within a wide temperature range of 50° to 1000°C. Safety and reliability in the storage of fundamental data and operating parameters are guaranteed.
