Universal Frequency Counter with Digital Display SM-2440

• alternative name: Heath Company

Our new frequency counter is a value leader that offers a lot of frequency range for the money. Engineers, hams and others will find the SM-2440 suitable for their needs and their budgets. One feature particularly attractive for hams is that the SM-2440 will count frequencies in the 1296 amateur band. It even reaches a maximum frequency of 1300 MHz.
