Price : Call

Code: #17758

Supplier: Deben UK Ltd.

A low-cost 3½-digit liquid crystal display readout of Electron Beam Probe Current. The free-standing meter is battery powered and measures from below 1pA to 2μA in 5 switched ranges. The meter has automatic zero correction but there may be small residual error not exceeding 5pA at 25°C. Where absolute readings are required on low ranges this small error may be subtracted from the reading obtained.
