Featured Equipment

Agricultural Science Starter Bundle

The Agricultural Science Starter Bundle contains the sensors required to perform several experiments in the Agricultural Science Manual.

Colorimeter and Turbidity

Wireless Colorimeter & Turbidity Sensor

This sensor can function as a turbidimeter or colorimeter and is capable of measuring absorbance and transmittance at six different wavelengths.

Wireless Conductivity Sensor

Wireless Conductivity Sensor

This waterproof sensor connects via Bluetooth® to measure both conductivity (ionic content in solution) and total dissolved solids.

pH Sensor

Wireless pH Sensor

Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
