IP-8 Measuring System

for Precise Monitoring of Setting Processes

The highly precise 8-channel ultrasonic measuring system was developed for the measurement of setting processes, strength developments and consistency changes. The IP-8 system is particularly suited for the measurement of building materials such as mortar&plaster systems, flooring systems, CO₂ reduced binders and gypsum-based products. The IP-8 system can be applied in research, development, production control and quality assurance.

Main features

+ Highly precise measuring system with a resolution of 0.05 µs

The high resolution of the IP-8 allows you to monitor setting processes with a precision, unmatched by any other test method applied to the monitoring of setting processes. 

+ 8 independently controllable channels

The 8 measuring channels of the IP-8 system function as independent measuring systems – assuring complete flexibility when carrying out measurements.

+ Intuitive Control and Evaluation Software – Available in many languages

The intuitive UltraTestLab software allows you to start a measurement with just two clicks. UltraTestLab contains many functions for fast and easy data evaluation. All results can be easily exported to Excel, guaranteeing you maximum independence and flexibility.

+ Easy handling and operation

The IP-8 System was optimized for application in mortar and concrete laboratories. Thanks to flexible silicone moulds demoulding is fast and easy. The transducer housings are made of 2 mm stainless steel and are designed to withstand regular breaking out of hardened concrete samples.

+ Long lasting and reliable

All our products are manufactured with the utmost care in our workshops in Achim and Oldenburg, Germany. Many of our measuring systems have been in continuous use for over 10 years.

+ Ideally suited for research & development, quality assurance and production control

The IP-8 can be used at all stages of production, from product development to production control.

Benefits of Ultrasonic Measurements

+ Strength development from initial mixing to final strength

The entire binding process, from initial mixing to final strength can be monitored with only one measurement.

+ Fast identification of product characteristics

Measurement results are immediately visible and can be followed live. Differences between product formulations, production batches or ambient conditions can be identified at an early stage.

+ Save up to 30 % development time and cost

According to our customers, application of the IP-8 can lower development time and cost by up to 30%.

+ High precision – unmatched by other test methods

Get more and more precise data on the setting behavior of your materials than with any other available method

IP-8 Connector Box

The IP-8 Connector Box offers a simple plug & play solution for ultrasonic measurements in climate and humidity chambers. The connector box can be mounted near the cable aperture. Starting from the connector box, cables whose length we adapt exactly to the space available in the climate chamber can be used. Measurements can be performed from 0 °C to 80 °C. 

Compressive Strength Correlation 

The optional add- on module allows to correlate ultrasound velocity and compressive strength developments. The software module creates a mathematical correlation between ultrasonic velocities and compressive strengths. Once a correlation has been created, compressive strengths can be directly calculated from the ultrasound velocities. 

Logistic Fitting 

The optional add on software module Logistic Fitting allows the subdivision of the measured US-velocity curve into individual sections based on logistic terms. These individual terms can be correlated with the crystallization processes of cement hydration.
Software training for the Logistic Fitting module is offered by Wacker: Wacker Academy
