the tube is a tin oxide cathode with coaxial cylindrical thin-walled structure (pipe wall density50±10cg/cm2) pulse applied halogen tube, in the range of the surrounding medium temperature from-40°C to 55°C, it is used for detecting gamma rays of 20mR/h ~ 120mR/h and soft β rays of 100~1800 devariable/min · cm 2.

2. Instructions for use

2.1 keep tube shell clean

counter tube Shell should be kept highly clean. Reduce surface pollution as much as possible, otherwise the insulation resistance will be reduced.

2.2 Typical working conditions of application

the characteristic parameters of the counter are measured under the recommended working voltage, so users should use it under the recommended working voltage as much as possible to obtain the given characteristic parameters.

2.3 careful installation

care should be taken when installing the counter tube, and the output lead of the counter tube should be as short as possible. Anode and cathode lead-out should not be too stressed. Especially the pipe with glass shell should be more careful, otherwise the pipe will leak or tube shell broken.
