Dedicated Customer Support

INPHAZE provides comprehensive technical support on sample preparation, instrument setup, measurements, data analysis, interpretation and all the way to publications.

Spectrometer Unit

Features:
- Phase Resolution: 0.001O
- Magnitude Resolution: 0.002%
- Measurement Frequency: 1 milli-Hz ~ 1 Mega-Hz
- Small desktop footprint: 342mm(W) x 330mm(D) x 185mm(H)
- Back-end of the system: connects to PC via USB
- Fully shielded enclosure
- Standalone back-end / front-end design allows great flexibility in setup configurations
- Self-calibration using the Wizard in Control Software
- Calibration parameters are customizable to optimize performance for each application
- Designed to be shared by multiple users: the spectrometer hardwares always remain neutral - users load their individual calibration profile appropriate to their application

Amplifier Unit

Features:
- Sample Impedance Range: 10-1 Ohms ~ 1011 Ohms
- Front-end of the system: connects to sample electrodes directly or via chambers
- Flexible sample connection: "i+" and "i-" terminals pass the signal through sample
- "v+" and "v-" terminals sense sample response
- Fully shielded enclosure
- Mountable into the INPHAZE Faraday Cage (most common configuration)

Faraday Cage

Features:
- Fully shielded environment for samples
- Dark space when closed, critical for Solar cell samples
