| Spectral Sensitivity Characteristics (Long) | 260 nM | 
| Discharge Sustain Voltage (DC) | 300 V | 
| Background maximum | 10 min-1 | 
| [Recommended Operating Parameters] minimum quenching time | 2 ms | 
| [Recommended Operating Parameters] average discharge current | 0.3mA | 

The R2868 is a UVTRON UV on/off detector that utilizes the
photoelectric effect of metals and the multiplication effect of
gases. It has a narrow spectral sensitivity of 185 nm to 260 nm and
is completely insensitive to visible light. Unlike semiconductor
detectors, it does not require a visible cut-off filter, making it
very convenient to use.
