AUTOMATED EVAPORATIVE CAPACITY TESTER known as Dr NOACK'TEST
ASTM D 5800- NFT 60161 - DIN 51581-
The instrument consists of a solid block heating unit made from malleable aluminium alloy as specified in DIN 1725 sheet-1, with an insulated jacket and base against losses of heat. The core unit is made of a heating block, an inclined manometer and 2 Woolf flasks on a dedicated framed. The instrument is equipped with 2 spirit levels and a needle valve to regulate the depression.
Temperature measurement and regulation are made with an inox gained PT100 probe and a PID regulator protected by a password.
Each instrument is actually tested in the production facilities and is provided with a quality control report which includes pressure/temperature curve according to standard requirements.
The instrument is delivered with an evaporation crucible, a thermometer with its calibration certificate, wood metal, a wedge key for tightening the crucible, tubing and pair of gloves.
To avoid operator's attendance, an automated vacuum controller is recommended. This option can also be installed on previous generation instruments.
A graphic recorder specially designed for this test can record and print out both pressure and temperature throughout the test. This tool is of major interest for traceability in an ISO 9000 procedure environment. The instrument complies with the European Directives regarding operator and Environment safeties and is therefore bearing the CE label.
