Measure Photosynthetically Active Radiation with this easy-to-use Vernier sensor.

Delivers highest-accuracy measurements of photosynthetically active radiation (PAR), temperature, and tilt for both underwater and above water environments.

Measure photosynthetic light levels in both air and water.

High-precision monitoring of PAR, temperature, and humidity with effortless Bluetooth data offload, ideal for monitoring environmental conditions - from agricultural operations to academic research.

High-precision monitoring of photosynthetically active radiation (PAR), temperature, relative humidity (RH), soil electrical conductivity (EC), and volumetric water content (VWC) with effortless Bluetooth data offload, making it ideal for comprehensive monitoring of root-zone conditions.

A reliable, field-proven, battery-powered rainfall data collection and recording system that includes a HOBO® Pendant Event data logger integrated into a tipping-bucket rain gauge.

The Pressure sensor 400 is the optimal sensor for conducting physical and analytical chemistry experiments, such as approximating the adiabatic expansion of a gas, Charles' law experiments, and ideal gas law investigations. It measures absolute pressures from 0 to 400 kPa and operates with excellent accuracy over a wide temperature range. The robust metal fittings allow for a tight, leakproof seal to reaction apparatus.

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