Products Information
Simplified, Compact, Low-Cost Galvanometer Amplifier RoHS

I / V Converter (1M) T-IVA001BZ
Now fully RoHS compliant.
For use in very precisely converting ultra-low current output from a photodiode or photomultiplier tube
into voltage.
The design successfully minimizes any current leakage, and thus minimizes any error. Operates on a single power supply, and thus also supports use of batteries as the power supply.
