"micro"

Evaluate structure and material strength.

Collect acceleration, rotation, and altitude data in the classroom or in the field.

LabQuest® 3 is a powerful, advanced, easy-to-navigate, and versatile data-logging solution for STEM students.

Hach Paddle testers allow fast, easy screening of water samples, solid surfaces, and non viscous liquids where unsanitary conditions may exist. The paddle is a double-sided slide attached to the vial cap. Each side of the slide is used to perform a separate test. The slide has a molded-in grid for easy colony counting without opening the optically clear, leakproof vial. Paddle tester, total aerobic bacteria/yeast and mold (tryptone glucose extract agar/sabouraud dextrose agar).

The Go Direct Respiration Belt measures human respiration rate.

The perfect way to introduce STEM, robotics and computational thinking.

This project kit makes coding and engineering design accessible to students in the classroom.

The Go Direct Sensor cart features built-in, wireless sensors for one-dimensional dynamics and kinematics experiments.

Codey rocky is an entry-level coding robot for STEAM education.

This multiparameter meter is a rugged, waterproof multiparameter meter. This meter's multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, and temperature. The multiparameter probe transmits readings digitally to the meter, where data points can be displayed and logged. The complete water quality meter is simple to setup.

Sensor measures the ability of a solution to act as an oxidizing or reducing agent.

The Go Direct Radiation Monitor detects alpha, beta, gamma, and X-ray radiation.

The Go Direct O₂ Gas Sensor measures gaseous oxygen concentration levels and air temperature.

Designed for use in situations in which low thermal mass or flexibility is required, the Go Direct Surface Temperature Sensor connects wirelessly via Bluetooth® or wired via USB to your device.
