control unit, flexible temperature probe (1.7mm OD), blanket and plastic cover for the blanket. Blanket size 15 x 20cm RAT/MOUSE BLANKET SYSTEM, 230V The flexible probe is a precision thermistor encapsulated in a bead of epoxy resin at the top of a flexible hollow plastic tube. The 1.7 mm diameter probe is 100 mm (4 in) long and has a 2 m (6 ft) long cable with plug for attachment to the control unit. The output of the temperature sensing probe is used by the control unit to proportionally control the DC supply to the blanket. This method of control alleviates the interference problems associated with that of nonproportional control, such as switching contacts, thus enabling the system to be used in conjunction with high-gain recording systems. The control temperature is adjusted using the rotary encoder and can be set between 20° and 50°C (68° and 122°F). The control temperature is continually shown in the main display alongside the actual temperature. The blanket consists of a highly flexible insulated heating element, which can be folded without risking internal damage. It is electrically floating, with respect to ground however, one end of the heating element can be grounded by a switch on the front panel of the control unit. The system operates satisfactorily whether or not the blanket is grounded. Special circuitry eliminates electrical noise thus permitting sensitive recordings. 230V, temperature controller with large display, audible and visual alarms,
