An instrument that can continuously monitor air for tritium has been developed. It utilizes a flow type ionization chamber and a vibrating reed electrometer. A response of double normal background is produced by 9.4 x 10⁻⁵ [mu]c H³/cc air; the presently accepted MPC is 2.0 x 10⁻⁵ [mu]c H³/cc air. Its operation is completely automatic.
