Abstract :
For magnetic measurements serial teslameter type H1-8 in a range (100divide110) mT1 that has an error no more plusmn0,15 % is used. For the operative temperature stability checking in a range of temperatures (18divide100) degC of magnets to be used in microwave devices the new method and additional device were developed. The magnets from alloy CS-25 of different manufactures have disorder of values of reversible temperature coefficient of an induction from - 1,9 % up to - 4,8 % on 100degC as has been shown. The effect of samples form on measurements is not shown
