This ‘Multi Counter’ is a compact and versatile instrument for general laboratory timing to 0.1 mS, counting, measuring frequency or rate and for performing Geiger counting.
The IEC Multi Counter with frequency, Geiger counting and audio amplifier with speaker is the most powerful of all the IEC Timer range. It is 220/240V.AC mains operated with a bright red LED display and sloping front panel for ease of using and viewing.
Each of the 3x modes (Timing, Counting/Freq and Geiger) has a set of ‘Functions’ to select the type of function you want for the mode you selected. All selection is by LED and the indication reminds you always of the mode and function that is operating.
