4-Channel Controller

Multi-Channel Type Supporting Simultaneous Measurement and Multi-Point Comparison

The 4-channel controller is a multi-channel unit capable of independently controlling up to four sensors.
It is ideal for multi-point monitoring, comparative evaluation, and long-term reliability testing.
It is suitable for multi-point monitoring in ASTM testing, simultaneous comparative evaluation, and long-term reliability testing.

Features

Heater control and measurement signal processing possible for each channel

Integrated management of all channel states via dedicated application

Ideal for comparing and evaluating different materials

Compliant with ASTM E1559/E2900 testing

High-Precision Simultaneous Measurement with Minimal Sensor-to-Sensor Variation is Achievable.

Results from simultaneous measurements using four sensors connected to a 4-channel controller confirm that peak temperature variation during outgas desorption remains within ±1.5°C.
This demonstrates extremely low variation between QCM modules, ensuring high reliability for multi-point evaluation, ASTM testing, and reproducibility verification applications.
