SAII - MR-compatible Small Rodent Air Heater System

SAII software continuously processes the temperature measurements and sends an optical   control signal to the Heater Module. The rate of change of temperature is monitored and heater control is adjusted to minimize overshoot and generate a closed-loop control system. Mouse temperature variations of less than ±0.1 °C can typically be obtained during MR examination

• Fan Module supplies cool room air to the Heater Module located near the magnet bore.
• Heater Module turns on and off based on the animal’s measured temperature and a user defined set point.
• System can be controlled by the Model 1025 Monitoring & Gating System or by the Fiber Optic Temperature Module.
• The temperature of small animals can typically be controlled to ± 0.1 ºC.
