Frequency meters Ch3-84, Ch3-84 / 2 (electronically counted)

Models:	Reference generator	Conv. exploitation
Ch3-84	1х10^-7 for 12 m.	-10°С + 50°С
Ch3-84/2	1х10^-6 for 12 m.	+5°С + 40°С

Frequency meters Ch3-84 and Ch3-84 / 2 (electronically counted) are designed to measure the frequency of the sinusoidal and the pulse repetition rate, the period of the sinusoidal and the repetition period of the pulse signals, pulse duration. Differs in high accuracy of measurements, a wide range of working temperatures, low cost.
