A single polycarbonate chamber designed to integrate sensors for controlled-environment experiments such as fermentation and plant / cricket respiration.
3 interconnectable polycarbonate chambers for building your own ecosystems. Designed to easily integrate sensors for quantitative environmental measurements.
PASCO’s Light Sensor is ideal for indoor and outdoor relative light intensity experiments.
The PASPORT Water Quality Colorimeter is designed specifically to support the chemical analysis of water samples using PASCO’s ezSample Snap Vial test kits.
This rack filters 0%, 25%, 50%, 75% and 100% of incident light to simplify the study of primary productivity.
Allows students to measure temperature by detecting emitted infrared from objects without contact. For use with PASPORT Interfaces.
Set of 5 clear PVC taps for water flow visibility when designing and constructing pipe networks. For use with an Absolute Pressure Sensor.
Allows students to explore the rate of water movement and quantify pressure changes occurring in the system.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Alkalinity test vials.
Designed to be placed in air or water flow. When connected to the General Flow Sensor, aids in measuring pressure differences.
