Two, ~6 cm square, replacement meters for radiation survey instruments. One of the meters serves as a dual-function meter. It can indicate the count rate over a 0-200 k counts per minute (CPM) range as well as the instrument voltage range from 0-2.5 kV while the other is a one-range meter scaled for the 0-10k MR/H range. Both the meters are manufactured by Tracerlab.
