Imada releases a new generation of durometer models

Northbrook, IL — Imada Inc. has introduced two new lines of automated durometer systems designed to deliver faster, more consistent hardness measurements for rubber and plastic materials across laboratory and production environments.

The company announced the release of its AAD and AAX Auto Averaging Digital Durometers alongside the ATD Series Auto Durometer Hardness Testers, expanding its portfolio of precision testing equipment.

Both product lines are engineered to improve repeatability and reduce operator involvement by maintaining constant load, speed and hold time during testing, in compliance with ASTM D2240.

The AAD and AAX models feature an integrated rotary indexing table that automatically moves samples between measurement points and calculates an averaged hardness value. The systems support multiple Shore scales, including A, B, C, D, E, O and DO, as well as Asker C, making them suitable for a wide range of materials.

The AAD model includes USB connectivity, while the AAX adds wireless data output. Both systems also offer programmable test parameters, OLED displays for improved visibility and internal memory for storing up to 400 data points.

Imada said the automated averaging function allows users to perform between two and 99 measurements per test cycle, improving consistency and minimizing variability between readings.

The ATD Series, which includes the ATD-L and ATD-H models, is designed for industrial durability and flexible testing applications. The ATD-L supports Shore A, B, E, O, OO and Asker C scales, while the ATD-H is configured for Shore C, D and DO scales.

Key features of the ATD systems include automated motion control, auto height adjustment for faster setup, and an auto contact function that ensures even contact with the sample surface before measurement begins. The testers also include multiple measurement modes, such as peak, timer hold and real-time analysis.

Data from ATD systems can be transmitted via USB or stored internally, with optional software available for advanced reporting and analysis.

According to the company, both product lines are designed to streamline testing workflows while maintaining high levels of accuracy and repeatability. Calibration certificates traceable to National Institute of Standards and Technology are included, with optional ISO-17025 certification available for certain configurations.

The new systems are intended to support quality control, research and production applications where precise hardness measurement is critical.
