Overview
Hamilton VISIFERM MA 425 H4
Overview
Designed especially for production environments, the new VisiFerm mA is a 2-wire sensor with 4-20 mA standard or digital HART signal output, and ATEX & IECEx approval. The new VisiFerm mA mitigates the negative effects of aging, temperature, and photobleaching in order to reduce the frequency of calibration and deviation reports
- Longer cap and sensor life
- Less frequent calibrations
- Easy installation with 2-wire connection
- Direct analog 4-20 mA or digital HART communication
- Calibration, verification, and maintenance data accessible via ArcAir app
