105T-L has been replaced by another product and is no longer available. Some accessories, replacement parts, or services may still be available.
The 105T Type T thermocouple has been replaced with the 105E Type E thermocouple. The 105T consisted of 24-gage, shielded, copper wire and constantan wire. The copper wire and constantan wire were joined at a measurement junction that was electrically isolated from the soil (or other media). Electrical isolation avoided measurement errors due to differences in ground potential.The "-L" on a product model indicates that the cable length is specified at the time of order.
