This Geiger counter is used to count the decay of various radioactive sources, and in use, the "Geiger counter sound" is heard - one click for each recorded impulse from the GM tube.
The counter can perform both single measurements and repeated measurement series. In the latter case, the latest complete count is displayed for an entire measurement period - while the new measurement counts up in a secondary display. The measurement periods can be divided into these fixed time intervals: 1, 10, 60, 100 or 300 seconds. After each measurement period a low beep is heard (this can be done silently).
The counter can be connected to GM pipes of various models with either BNC or Jack connectors, just required that the pipes have a GM supply voltage corresponding to the regulated voltage range of 300 to 700 V. The control also allows to evaluate on a GM pipe counting characteristic. During the adjustment, the count number can be displayed simultaneously.
As an option, a Usb communication cable (512565) can be obtained - so that data can be collected with Datalyse (The program is downloaded from this link: datalyse.dk). Datalyse is a freeware program developed by a Danish physics teacher. The program works fine with 513610 and is wired with 512565.
Via a cable with jack connector (512560), 5 V pulses can be transferred to data collection equipment or the like, for example to Pasco with the digital adapter PS-2159, which makes it possible to perform data analysis with eg. Sparkvue.
Tension of the GM counter takes place either by six. 1.5 V AA batteries (this provides several days of battery life) or with AC adapter 355050. Both parts are included.
"Stand by" occurs automatically after one hour of inactivity.
Dimensions: 234 mm x 108 mm x 65 mm.
(The model has replaced earlier model 513600).
