DASCOR is a world leader in providing autonomous data loggers for ruminal research with over 500 units already in the field.  Standard LRCpH loggers currently in production include support for measuring Temperature, ORP/REDOX, pH, and battery voltage. One or two more positions can be added for additional optional sensors.  Data rates can be set from one scan per second to one scan per 18 hours.  114,687 data points can be stored in non-volatile memory.  A 9-Volt alkaline battery supports at least 5 tests which completely fill memory.  Support software and interface cables are provided to allow a PC or laptop to calibrate and set up the loggers for tests, and to download the subsequent data into a spreadsheet compatible .csv file.

With ongoing active support from the research community and the manufacturer of our sensors, DASCOR has continuously improved the performance and long term reliability of both the loggers and sensors.  pH sensors in particular now have significantly extended life and reliability, along with calibration stability and repeatability demonstrated in use over multiple field trials.   Electronics are based on logger engines with over a decade of use in rugged military and oil-field applications.  As new sensor designs are proven in actual field use, the overall size of the loggers is being reduced, with  bolus units available for use in smaller ruminants for esophogeal insertion. Wireless (RF) links are also being investigated, and will be introduced when a unit suitable for long term commercial use is available.

Starter Kits are available at a reduced price for first time users.   Starter kits are limited to one per organization and may be factory refurbished units.   Units are also available for rent.  Discounts off the standard prices are available at 5, 10, and 20 units.  A further discount is available to bona fide public Universities and government research agencies.  Inquiries regarding custom modifications and special sensors are welcome! Please email us requesting the LRCpH Price Calculator Excel spreadsheet.

DASCOR also sells the consumable sensors, and support items such as Bar-Diamond cannulas and cannula plugs.
