CHINO AH4000 Hybrid Memory Recorder (Dot-Printing Type): Simultaneous Chart and SD Card Recording

Overview

The AH4000 is a CHINO dot-printing hybrid memory recorder that prints with a 6-color ribbon on a chart with an effective width of 180 mm while writing measurement data to an SD card. With the optional SD card playback function, the chart can be reprinted from SD card data if the paper record is lost. A monochrome LCD shows measured values for all channels, and a 180 mm LCD bar indicator is also provided. A USB port is standard, allowing setup and data collection with the free TRAMS software; with optional Ethernet, the recorder can be monitored via a web browser and send alarm notifications by e-mail. Models are AH4706 (6 points), AH4712 (12 points) and AH4724 (24 points); the pen-type AH4000 is available on request.
