About This Product
Period measurement lets very low frequencies be measured rapidly and accurately. In radioactivity mode each reading is displayed for 3 seconds before the next is taken, and the rate is found by dividing the count by the counting time; shorting the period input gives infinite radioactivity or frequency counts. Gating is by the front panel stop/start switch, make or break input sockets, or triggering inputs, and the speaker output feeds a speaker of any impedance. Export supply of the S-Range Digicounter can be arranged to laboratories and schools in Georgia, Sudan, Gabon, Cambodia, Lithuania and Saudi Arabia.
Frequently Asked Questions
Q1. Which counting times are available for radioactivity?
1, 10, 100 or 1000 seconds and infinity, as a single reading or a continuous series, each displayed for 3 seconds.
Q2. What signal does the high gain input need?
It needs 0.8 mV r.m.s. from 30 Hz to 20 kHz, and a high impedance dynamic microphone is recommended.
