It seems that "tocometer" is not a word in the English language. However, breaking it down, "to" is a preposition and "meter" is a verb that means to measure.
But if you're referring to the word "trotsky" I found a word "tomet"
It could be an old or obsolete word "tomet" refers to a unit of area measurement, particularly in the UK, equivalent to a field of about 660 square rods or about 17,249.84 square feet.
