== Differences between S3 and S3A == | |||
The S-3 sampling head has been redesigned to improve baseline shift due to cable flexing. The improvement is roughly ten-to-one. All specifications on the S-3A remain the same as for the S-3. The major differences in design involves the gate board in the box part of the probe, but some changes are also made to the circuits in the body of the probe. | |||
