The dataTaker DT85 smart data logger provides an extensive array of features that allow it to be used across a wide variety of applications. The DT85 is a robust, stand alone, low power data logger featuring USB memory stick support, 18 bit resolution, extensive communications capabilities and built-in display.
The dataTaker DT85’s Dual Channel concept allows up to 32 isolated or 48 common referenced analog inputs to be used in many combinations. With support for multiple SDI-12 sensor networks, Modbus for SCADA systems, FTP and Web interface, 12V regulated output to power sensors, the DT85 is a totally self contained solution.
Connect an array of sensors through the versatile analog and digital channels, high-speed counter inputs, phase encoder inputs and programmable serial sensor channels.
Temperature, voltage, current, 4-20mA loops, resistance, bridges, strain gauges, frequency, digital, serial and calculated measurements can all be scaled, logged and returned in engineering units or within statistical reporting.
Set up sampling, logging, alarm and control tasks to suit your own requirements while interfaces for smart sensors, GPS and other intelligent devices expand the DT85 flexibility.
With the standard unit able to store up to 10 million data points (expandable) you can log as much or as little as you need. Overwrite or stop logging once allocated memory is full, archive data on alarm event, copy to USB memory or transfer via FTP/ Email, the choice is yours.
Communications features include RS232, USB and Ethernet, connect to the DT85 locally, remotely through a modem or over the Internet. The web interface allows users to configure the DT85, access logged data and see current measurements as mimics or in a list using a web browser.
FTP/ Email provides data to your office over the internet or wireless network, without the need for polling or specific host software.

Our client – a major research organization – had a project where they were to compare the effects of various surfacing materials on a series of tanks and how efficient these surfaces were in reducing temperature losses. The temperature in the tanks was to be cycled up to 60°C by internal steam coils and allowed to cool. The temperatures were to be logged at all times with sensors at various depths within the tanks. Data collection needed to be simple, but remote communications were unnecessary…Read More
In the surrounds of the city of Guangzhou, a spell of cold weather poetically named the cold winds, threaten to slash the yields from the second rice crop of the season by 50%. These conditions frequently occur within the months of September and October. Rice breeders at the Guangdong Academy of Agricultural Science aim to develop new rice varieties that can withstand and thrive in the cold dew winds. Apart from records of average daily temperature, they lacked precise information on the severity of the conditions which the new varieties have to endure. The lack of data severely hampers the development of the new rice varieties. A monitoring solution was therefore required to further this research…Read More
