Uses an infrared beam which passes between the two endpoints of the sensor probe to count drops. As liquid passes through the infrared beam, infrared light is scattered and not noticed by the infrared detector on the opposing side.
Includes a durable plastic drop counter probe attached directly to the sensor’s body by a rubber-coated wire
and a threaded rod for easy connection to retort stands or other labware.
Used in the fields of Exercise Science, Biology, Physiology, Human Health, etc.
Uses the piezoresistive effect.
Includes a blood pressure cuff attached directly to the sensor by flexible rubber tubing and a pump with pressure release valve attached directly to the blood pressure cuff
Used in the fields of Chemistry, Physiology, Exercise Science, Biochemistry, Biology, Earth Science, Environmental Science, etc.
Includes a CO2 probe, attached to the sensor’s body by a durable rubber coated wire.
Includes a glass bottle.
The sensor is pre-calibrated at the factory.
The sensor offsets to the standard atmospheric CO2 concentration of 380 ppm in open air (assuming stable levels in the Earth’s atmosphere at sea level).
Used in the fields of Chemistry, Biology, Pharmacology, Biochemistry, Environmental Science, Physics, or even just to study the behavior of light waves.
