This is a 10' extension cable for data loggers compatible with the DSB.
Dickson's Replaceable Sensors are the easiest and quickest option for re-calibrating a compatible monitoring device. When your data logger is due for calibration, simply order the appropriate Replaceable Sensor with the type of calibration you need. You'll receive a new sensor in the mail and you simply detach the old one, replace it with the new one, and then you're done!
You can connect up to 5 extension cables to extend your sensor up to 50'.
