PrediktIR II Bulk Materials Moisture Gauge

On-line Near Infrared (NIR) Moisture Gauge for Bulk Applications


Replacing the PrediktIR, the PrediktIR II Bulk Materials Moisture Gauge has been designed to provide high accuracy,  stable and dependable measurement to the bulk materials industry at a cost-effective price. Using NIR non-contact technology, it is suitable for many types of continuous processes and will provide real-time moisture measurements, that can be used to tightly control the process and warn operators if the process is moving out of specification, thereby increasing yield and improving quality. Efficiency improvements can result in substantial cost reductions and investment payback in a matter of months.

What Our Customers Say…

We found that we were actually losing a lot of money due to not having the correct moisture content in our bricks, so back in January 2019, we decided to look into implementing some non-contact NIR moisture gauges to enable us to monitor this more effectively. We contacted LIMAB UK and installed two NDC Technologies’ PrediktIR moisture gauges in our priority clay prep. area. I am very happy with the PrediktIR gauges and having the ability to constantly monitor the moisture content has massively improved our quality control processes. We were impressed with the evident product knowledge and expertise demonstrated by the team at LIMAB UK and the customer service and aftersales support was great!

Scott Bamford – Technical Manager

I knew that some of the other Wienerberger sites had already purchased some NDC PrediktIR moisture gauges and I had heard that they were really improving the production processes and quality control procedures. I met up with some of the LIMAB team at ClayTech, and I was immediately impressed with their expertise and what they had to offer. After discussions with NDC Product Specialist, we went ahead and purchased four NDC PrediktIR gauges. The gauges have really helped us to monitor and have greater control of our water input system and we are already getting some really useful data. I would certainly purchase from LIMAB again in the future.

Philip Smallridge – Process Improvement and Quality Control

We got a call from John Miller from LIMAB UK back in 2018, just as we were finding our existing moisture gauge was failing. We discussed the possibility of replacing our existing gauge with an NDC gauge and invited John to come in for a site visit and to subsequently quote us for a PrediktIR. We were very impressed with John’s product knowledge and we decided to proceed with the purchase. We have found the PrediktIR to be very reliable and we are very happy with it.
