DT500 Series Datataker Data Loggers
DT500, DT505,   DT600 and DT605

The dataTaker DT500 Series
The dataTaker DT500 Series of general purpose, battery powered data acquisition and data logging systems measure inputs from most sensor types. Data can be conveniently and securely stored in battery backed RAM and removable memory cards. The dataTaker DT500 Series consists of four models:
• DT500 Basic Unit with Solid State Channel Selector
• DT600 Solid State Channel Selector & LCD Display and Keypad
The highest range of the DT500 and DT600 is ±2.5VDC.
The common mode range is ±3.5VDC, inputs are protected to ±5VDC

• DT505 has Relay Channel Selector
• DT605 has Relay Channel Selector & LCD Display and Keypad
The DT505 and DT605 also have a ±100VDC range, and on that input range the common mode range is also ±100VDC.

DT505 and DT605 look the same as DT500 and DT600
   - the difference is internal 

The DT600 and DT605 both have an integral display and keypad that allows users to view channel data, alarm status, and system information including time, battery status and amount of data stored.
Function keys allow keypad control over the unit's operation.

Datataker Windows Based Software
Datataker produces a range of Windows based software, which provides a simple interface for supervising the dataTaker DT500 Series.
Datataker's software allows you to manipulate data with statistical functions and calculations.  Alarms can be set for all channels, providing you with warning and control signals.

Datataker's Extensive Range
Datataker's extensive range of data acquisition and data logging systems are real time and stand alone, able to acquire, process and log data without direct computer control. The powerful yet easy-to-use hardware and software enables you to log a wide range of measurements and events.
More than 30,000 dataTakers are in use in over 55 countries - dataTakers are used in many applications including science, aerospace, mining, manufacturing, meteorology, agriforestry, hydrography, petrochemical, public utilities and transportation.
