Oxygen Sensor
BAROMETRIC PRESSURE
THERMISTOR
The Barometric Pressure Sensor (SB-100) is suitable for measuring barometric pressure with dataloggers.
Apogee originally developed this sensor for use with oxygen sensors which are sensitive to barometric pressure fluctuations.
The Thermistor Temperature Sensor (ST-100) is a small ceramic thermistor enclosed in a weatherproof housing. It is suitable for measuring air and soil temperatures with a datalogger. The temperature measurement range is -50 C to 70 C with an accuracy of 0.5 C.
