The TF-2 employs a small (0.016" , 0.4 mm diameter) Teflon sheathed probe to sense tail temperature. The probe's size allows it to interleave within the fine hairs that coat the tails of most rodents and make contact with the skin surface. The probe position is such that it is oriented at the point of most intense exposure
The TF-2 allows for the concurrent monitoring of up to three temperature "T"-type thermocouple sensors. Three temperatures provides full disclosure of the conditions under which the test was performed. Temperature channels two and three may be employed for rectal and room measurements. The TF-2 records all three temperatures at the time of tail-flick. All temperatures are sensed with 0.1°C accuracy over a range of 0-55°C. Full calibration of the sensors can be performed from the front panel to allow GLP validation.
The TF-2 maintains the halogen light source in a ready-state by keeping the filament pre-heated with a small current. A generic scale (0-25) defining stimulus intensity is user adjustable in 0.1 increments. Automatic cutoff of the stimulus, to prevent over exposure, is user adjustable from 5-30 seconds.
The TF-2 provides a automatic detection of tail flick (by photocell interruption) as well as an interactive (user performed) method. Both processes detect latency with a temporal resolution of 0.01 second.
The TF-2 includes basic animal management capability that allows identification.
The TF-2 is equipped with a PC interface and associated software for Windows. All data on the PC is stored in a simple .CSV format for integration with spreadsheets or statistical analysis programs.
