Includes: Each system is supplied complete with control unit, temperature probe, blanket and plastic cover for blanket. The blanket is supplied with a 2m (6 ft.) cable attached to a plug for connection to the control unit.



This homeothermic blanket system consists of three parts: a probe, a control unit, and a blanket. The animal is wrapped tightly in the heating blanket. The temperature-sensing probe is inserted rectally and the required temperature is set by means of the front control panel.

Probe Features

  • The flexible probe is a precision thermistor encapsulated in a bead of epoxy resin at the top of a flexible hollow plastic tube
  • The 1.7mm (0.07 in.) diameter probe is 100mm (4 in.) long and has a 2m (6 ft.) long cable with plug for attachment to the control unit
  • It is suitable for a wide range of laboratory animals from mice to dogs
Control Unit Features
  • The control temperature is preset at 37°C (98.6°F) at the factory, but can be adjusted within the range of 20° to 50°C (68° to 122°F) by means of a control on the front panel
  • An LCD display on the control unit continuously displays the probe temperature
  • A horizontal LED bar graph indicates the level of power being delivered to the blanket
  • When core temperature is substantially below the desired temperature the bar graph will indicate maximum power being delivered
  • The output of the temperature sensing probe is used by the control unit to proportionally control the regulated, low-voltage 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
Blanket Features
  • The blanket consists of a highly flexible insulated heating element, which can be folded without risking internal damage
  • The system can be grounded or operated with a floating ground option set through the control panel
  • The system operates satisfactorily whether or not the blanket is grounded
  • Special circuitry eliminates electrical noise thus permitting sensitive recordings
