Product Description

The next generation Advanced Quartz Crystal Microbalance analyzer from Michell Instruments is designed to provide reliable, fast and accurate measurement of trace moisture content in a variety of applications where keeping moisture to a minimum is of critical importance.

The analyzer provides consistently accurate measurements of trace moisture. This consistency is achieved using a self-calibration system, which adjusts the sensor with reference to an internal moisture generator. The moisture generator is supplied with a calibration traceable to NPL and NIST, so long term stability of its measurements is guaranteed.

Product Features
- Precision measurement from 0.1 to 2000ppmV
- Simple, low cost, on-site maintenance
- Accuracy of 0.1ppmV or 10% of reading, whichever is greater
- Reliable measurement even in varying sample conditions — analyzer corrects automatically for flow variations
- Unaffected by changes in background gas composition
- Long intervals between maintenance
- Dryer can be replaced by the user in 10 minutes
- Intuitive user interface
- Ethernet or USB digital communications
- SD card datalogging
- Optional internal sample handling and bypass loop
