Features
The OMEGA™ CDH-SD11 is innovative and easy to operate. What sets the CDH-SD11 apart from other
conductivity meters is that it incorporates a real-time SD card data logger. The CDH-SD11 measures
conductivity, TDS (Total Dissolved Solids) or salt concentration using a graphite plate electrode for long
life. Downloading data from the SD card into an Excel spreadsheet allows the user to do further data or
graphical analysis without special software. The CDH-SD11 has a wide variety of applications from water
conditioning, aquariums, beverage manufacturing and fish hatcheries to food processing, photography,
paper and plating industries, educational and other laboratories.

K10 calibration solution not available!
Purchased this meter with K1 and K10 electrodes. I want to perform a calibration of the K10 (0-200mS range) and the manual asks for a 12.8mS solution. No STD solution of 12.8mS available at Omega. I call Omega and I am recommended to buy a 45mS solution to calibrate K10, which I do. Once I receive the solution, I find out there is no way to tell the meter that the solution is not 12.8 but 45mS! The engineering dept confirms that too on the phone... A bit unfortunate to not being able to calibrate such instrument! I will send it back...

Will this measure salinity for seawater? I am not sure what "option" vs. "supplied" means in the description for the range in conductivity. Does this mean selectable or does it mean that an optional accessory must be purchased?
Thank you for your inquiry! Yes the salinity for seawater can be measure using this device. In the description "supplied" refers to the range covered by the supplied electrode while "option" is for alternative electrodes that are available for purchase.
