GT68R Touchscreen Paperless Recorder
This is an advanced, high-quality industrial paperless recorder, widely used for recording process parameters in production, experiments, and testing. It real-time acquires output signals from various sensors, such as temperature, pressure, liquid level, flow rate, pH value, conductivity, and dissolved oxygen. It supports input recording of various signal types including current (mA), voltage (mV/V), resistance thermometers, and thermocouples. The fully isolated channel design effectively resists industrial field interference, ensuring stable operation and accurate signal data.
