WP-18 type paperless recorder

18-bit A/D analog input all the channels can 200 millisecond sampling 6.1' TFT color LCD display 24 kinds of operate mode

We ingeniously designed WP-18 type paperless recorder is the first high-resolution and real color paperless recorder in China with diverse unique functions.

Adopting 6.1' TFT color LCD display, this recorder has multiple display functions and WINDOWS interface. Its resolution is up to 640×480 pixels.With infrared detecting functions, it can automatically detect and close the LCD display to prolong the life-span of LCD display.Inserting-card plug and play type input and output I/O card makes the user not need to return to manufacture or order another new meter when expanding the input or output channel amount and only need to corresponding input or output card, plug and play, self-configuration.Complete photoelectric isolation among channels and between input and output. Input dividing number can be switched.The using of reliable FLASH EMS memory and high-compression calculation method makes the data storage more and more reliable.The highest accuracy: 18-bit A/D analog input.Quick sampling ratio: all the channels can 200 millisecond sampling.24 kinds of math operate mode can be programmed by user himself, such as the plus-minus, multiply-divide, evolution, timing, counting and integrating among channels.Can output data by universal serial interface (RS-232, 422, 485) or Ethernet.
