1、 Product Overview:
The OW-4000 series paperless temperature recorder is applied in the field without manual monitoring, recording measurement data 24 hours a day, controlling and alarming its measurement points, using ultra large data storage, supporting USB data collection for historical data viewing and analysis, and is an ideal product for realizing automated control systems.
The paperless temperature recorder has a universal signal input function, such as the input of various instrument signals such as flow meters, transmitters, thermocouples, thermistors, currents, etc. A recorder can have 16 channels, each of which can be used simultaneously with complete isolation between each channel. Adopting a widescreen LCD display, multi-channel measurement data is displayed simultaneously, with a fully Chinese operation interface and real-time curves, alarm information, historical records, report printing, etc.
