We are bulding static chambers for CO2/N2O emissions from soils. We are not sure which kind or brand of termometer to include for measuring air T°C variations inside the chambers.
the design of static chambers probably needs more than one thermometer per chamber due to thermal gradients. A reliable solution is a network of thermistors that are cheap and reliable and a suitable PC AD converter as in the free Arduino example: http://www.circuitbasics.com/arduino-thermistor-temperature-sensor-tutorial/
