There are two camps on how the Rice (or Maximum Specific Gravity) test needs to be done in order to be correct. One is team Autorice, who love that the unit performs the entire test automatically, and the Other is team “This is the way we’ve always done it”. “The way we’ve always done it”…
NCAT Calibration A Gordon NCAT Calibration is one of the most reliable calibrations you can get for your lab. It’s not because we think we’re the best at them ( Although we probably are), but because we go above and beyond when it comes to doing our homework. How the NCAT was made The NCAT…
If you have ever called in for maintenance, you’ve been asked this question. Do you know which series you have? It’s your typical deer in a headlights situation. There’s always an audible silence before the caller ends up saying, “no” and “how can I find out”? Today, we are going to tell you the difference…
The T209 rice test is the worst possible situation for a vacuum pump. By design, vacuum pumps need to be free of contaminants and never EVER allow water in. So what do we do? We put a container of water and hook it up in line with our pumps. Because we don’t have time to…

There is a metal box that sits inside of your NCAT Ignition Oven. It’s rectangular and sits directly under the burn chamber. That box is the reason why your oven can perform the burn-off method so accurately, but that same box also has the potential to ruin hours, days, or even months of testing if not installed…
The NCAT ignition oven has been at the forefront of mix design since the late ’90s. In that time there have been a few improvements over the form and function of the unit, but for the most part, the NCAT ignition oven has stayed the same. You put your mix in the chamber and the…
