RH test results varying

[Rubensgt40]

AH, well this is where I get confused because of the difference between the Wagner system and the others (I've only used Protimeter).

With the Proti system, the thing you're inserting into the concrete is just a "sleeve", and the probe is the thing attached to the handset on a cord, and that probe constantly needs to be calibrated/ kept at the right temp/ etc.

With the Rapid RH, the thing you're inserting into the concrete IS the "probe" and the little orange reader thingy kind of takes the place of the handset...hence no need to calibrate the probes, because they're all expendable..

Is that about right, if you'll pardon the excessively layman-like termage?
