The AirTherm SMT is a new generation of heat control from WPI designed to be used in Live Cell Imaging applications with microscopes that are fitted with a full microscope environmental chamber enclosure. The standard AirTherm SMT controls temperature and, as an option, humidity.

The AirTherm SMT uses a PID control algorithm to maintain tightly controlled loops of heat and humidity environment control.

With AirTherm SMT, the temperature of the sample and microscope optics can be controlled to within 0.2°C. During operation, air is drawn out of the chamber through a flexible hose, heated by the AirTherm SMT heater, humidified (if desired) and re-circulated to the chamber by the return hose.

  • Precision heat controller for use in live cell imaging and custom incubators
  • Electrically and acoustically quiet
  • Quick, precise response to thermal change

 The system is typically used in a closed loop configuration.

A typical AirTherm SMT installation places the heated air inflow at the bottom and the cold air return at the top of the microscope chamber.


The AirTherm SMT system includes:

  • AirTherm SMT
  • Coil-reinforced heater hose pieces, hose clamps
  • Temperature sensor for remote placement in environmental chamber
