The one I bought on ebay measures temp in Fahrenheit, so this must be the new one??? Does yours measure in celsius?
"Digi-Spec-TSS Meter is an innovative 3-in-1 tool that incorporates digital tests for temperature (Fahrenheit), salinity (ppt) and specific gravity (e.g., 1.024) displayed in scales commonly used by aquarists without the need for conversions."
It also says, "**BRAND NEW** Digi-Spec TSS - Lab Grade Digital Temperature, Salinity, Specific Gravity Meter Retails at $149, same as JBJ DigiLab but 1/3 the cost!" ... so, it sounds like they are the same instrument, just with different labels.
I hope this turns out okay. I'll let you all know... fingers crossed.
