Scaler Timer
Scaler Timer (Product Code: SLE/PHY/43) is a general-purpose counting and timing instrument used for radioactivity counting with a GM tube and for millisecond digital timing in physics laboratories. Its 6-digit bright green LED display holds up to 999,999 counts or seconds, with manual counting or timed counts of 1, 10 or 100 seconds and manual or electronic triggering. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Scaler Timer Used For?
In nuclear physics practicals, the Scaler Timer provides the GM tube voltage of 300 V to 500 V, counts each pulse and totals them, so students can measure background radiation, count rate against distance or absorber thickness, and half-life. The press-to-read switch lets them check the tube voltage, and the loudspeaker gives an audible click for each count when a class needs to hear the random nature of decay.
The same unit doubles as a millisecond timer for mechanics, with start and stop triggered by hand or by light gates, which suits timing a falling object, a trolley or a pendulum. Having one instrument serve both the radioactivity and the mechanics practicals is useful for any GM counter set-up in an Indian school or college lab where bench space is limited.
What to Specify When Ordering
- Whether you need the Geiger Muller Tube Holder and a GM tube for radioactivity counting.
- Whether you will trigger timing with light gates, and how many.
- Your mains supply: the unit is specified for 230 V ±5%, 50 Hz.
- Number of units per laboratory.

Frequently Asked Questions
What can the Scaler Timer count and time?
The Scaler Timer counts GM tube pulses for radioactivity work and also works as a millisecond digital timer. Its capacity is 999,999 counts or seconds, with manual counting or timed counts of 1, 10 or 100 seconds, and auto ranging on timing modes.
What GM tube voltage does the Scaler Timer provide?
The Scaler Timer provides a GM tube voltage of 300 V to 500 V. A press-to-read switch shows the voltage actually applied to the tube, so students can set it to suit their GM tube before they start counting.
Can the Scaler Timer be started and stopped by light gates?
Yes. The Scaler Timer accepts manually switched start/stop or light gate operated start/stop as timing inputs, so the same instrument can time motion experiments as well as count radioactivity in the physics laboratory.
What power supply does the Scaler Timer need?
The Scaler Timer runs on 230 V ±5%, 50 Hz mains and is protected by a 315 mA (L) slow-blow fuse. If your laboratory uses a different mains supply, mention it in your enquiry before ordering.
Is a GM tube included with the Scaler Timer?
A GM tube is not listed as part of the Scaler Timer. For radioactivity counting, add the Geiger Muller Tube Holder to your order and ask us about a suitable GM tube in the same enquiry.
Is a calibration certificate available for the Scaler Timer?
Please discuss any calibration-certificate requirement for the Scaler Timer with us before ordering, stating the document your purchase file needs. We will tell you what can be provided for the unit you are quoted.
