CAUTION: High Voltage Warning!

This product is operated at high voltage. Extreme care must be taken to ensure operator safety and to avoid

damage to other instruments. Avoid direct contact with the photomultiplier when high voltage is applied. Avoid

placing conductive material close to the cathode.

All given values are nominal/typical @ 20 °C ambient temperature; specifications subject to change without

notice.
