Description

The Pressure Sensor (150-1,150 mbar) is an absolute gas pressure sensor that measures applied external pressure relative to zero pressure reference sealed inside the sensor.  

Common usage

The Pressure Sensor can be used as an altimeter (measuring your current height) and as a barometer for various meteorological measurements.  Typical uses include investigating the evaporation of water from terrestrial plants – transpiration, measuring the photosynthesis rate in water plants, measuring the respiration rate of germinating seeds, investigating the effect of light on photosynthesis rate and as well as examining the Ideal Gas Law.

Specifications

• Range: 150 to 1,150 mbar
• Accuracy: ±1 % over entire range
• Resolution (12-bit): 0.25 mbar
• Default Sample Rate: 10 samples per second
• Response Time (for 90% change in reading): 1 ms
• Operating Temperature: 0 to 85 °C

Description

Fourier’s stainless steel Temperature Sensor is both simple and durable.  It is covered with a protective isolating material, making it significantly stronger than a traditional glass thermometer.  The sensor connects directly to the data logger using a standard mini-din cable.

Common usage

With a range of -40 °C to 140 °C, it can be used for experiments in Chemistry, Physics, Biology, Earth Science, and Environmental Science.  It is particularly well suited for conduction water and other chemical solution temperature measurements.
