Features

• Four multi-purpose input channels
• Each input channel will read resistance, 0-5vDC or a contact closure as standard
• Over 60 direct connect sensors are available and may be mixed and matched in any combination.
  
• Data retention of over 200 years with no power.
• High accuracy, up to +/-0.15°C and +/-0.25% F.S. with no calibration.
• Adjustable resolution of 8, 10 or 12 bits (lowering resolution increases reading storage capacity but decreases accuracy, see specifications).
• Wide operating temperature range -40°C to 60°C (-40°F to 140°F).
• Certificate of Validation, traceable to NIST, included with each unit.
• Long battery life, Can provide up to 2-3 years operating (including sensors) without external power.
• Optional Pulse Module for tipping bucket rain gauge, gas and water meters, and kWH meters.
• Optional Scaling Module for +/-5, 0-10, 0-20, 0-30, 0-60vDC and 4-20mA signals.
• Optional Thermocouple / Millivolt Modules for thermocouple or millivolt signal.
• Windows based software (full version available for free download) for logger setup, data transfer, graphing and data export.

The XR440 Data Logger was designed for easy setup and trouble free operation. Direct-connect sensors include Temperature, Humidity, Pressure, AC current, AC Voltage, Light, soil moisture and Process Signals. The Data Logger's four input channels accept any combination of the above sensors, plus resistive, 0-5vDC signals and contact closures.

Stand alone: The XR440 Data Logger does not require a computer while it is logging. You connect it to a computer using a serial RS232 cable (Part No. IC209, listed below) for setup, data transfer or to display readings in real time. You can also communicate with the Data Logger using cellular or land-line modems, or a wireless link.

Long life: Battery life with any combination of sensors is over two years (continuous operation). All sensors are powered from the logger's battery. The battery is user-replaceable (standard 9 volt size).
