Questions

  • Answer:

    The only probes we offer are the three shown as related products on the item product page.  All of these use a solution bottle.

    They do offer a "spear" style probe for this logger (shown on accessory tab) however it is only for temperature and it uses a mini jack connector and not a BNC.

  • Answer:

    The manufacturer for this product doesn't specify the total number of readings that can be recorded on various sized SD cards.  The files this logger produces are small .xls files so the total number of readings that could be stored on a 16GB card would be very high.  While the manual or specification doesn't state the maximum number of readings it does say that the logger will write a maximum of 10 folders to the SD card and that each folder can contain up to 99 .xls files.  Each file can have up to 30,000 rows of data.  How quickly you generate data will depend on the sample rate or recording method you choose.
