Hycal - Model Mk4 - Portable Advanced Dissolved Hydrogen Analysis System - Manual

The Hycal hydrogen measurement system provides rapid, accurate measurement of hydrogen dissolved in molten aluminium and its alloys. The system can be used to: Perform spot measurements to check melt hydrogen levels prior to casting. Continuously monitor dissolved hydrogen levels. Control a metal treatment process in order to achieve a desired hydrogen concentration e.g. degassing. The probe provides simultaneous measurement of dissolved hydrogen and temperature. Hydrogen sensing is achieved by an electrochemical hydrogen measurement cell located in the probe tip. Calibration is assured through individual calibration of each sensor in a precisely controlled hydrogen atmosphere, and through testing of each probe prior to shipment. Measurement precision throughout the lifetime of the probe is ensured through an integrated gas cylinder and purge system which prevents blockage and oxide build up. The gas system may also be used to perform in-situ calibration checking of the probe.
