IX-400 4, 8, 16 Channel Single Ended Recorders

The iWorx 400 Series recorders are economical, high performance four, eight, or sixteen channel data recorders for use with a broad range of analog amplifiers. The recorders offer 16-bit resolution at a maximum data collection speed of 10 kHz, making them appropriate for most research applications.


SKU IX-400 Category Tag


The 400 series recorders use a 16-bit A/D converter to sample data over its full input range of +/-10V at speeds up to 10kHz. The low noise (<1mV) greatly reduces the need for gain and offset.

LabScribe Software Provides Powerful Analysis Tools

Installation and operation of the LabScribe acquisition and analysis software is easy and straightforward. LabScribe software allows ‘one-click’ control of the entire acquisition process, plus a large library of standard analytical functions to process data. The 400 series recorders are powered via a USB interface to any Macintosh or PC, eliminating the need to install special interface cards. Users are typically recording and analyzing signals within minutes of installation.It supports real units and a time based display that is not coupled to sample rate. The display can be configured to allow viewing of as many data points as the user desires. Scrolling, zoom-in and zoom-out tools, together with a searchable list
of user interventions, make finding important areas of data easy.

LabScribe provides a powerful array of built-in data analysis tools. It strikes a balance between the straightforward, general operations that everyone uses and the vertical, complex routines that only you use. The result is a powerful analytical tool that can go to work on your data right away, or be customized to do very specific and complex analyses.

Pressure Volume Loop Software Module
The iWorx Pressure Volume Loop Software Module is a plug-in software module foruse with iWorx data acquisition systems that performs pressure volume loop analysis for hemodynamic research in animals. The software module provides a powerful and easy to use tool for investigators to measure and analyze the hemodynamic parameters of cardiac and pulmonary pressure and volume data acquired by an iWorx recorder.

Exceptional Value
The 400 series recorders provide turnkey continuous recording solutions at a fraction of the cost and complexity associated with systems requiring PCI bus plug-in cards. No breakout box is required, as connectors are part of the enclosure. In fact, no other hardware is required to get up and running.
