Over the years, we’ve offered submersible pressure transducers from various manufacturers for measuring pressure, depth, or level in hydrological applications. We are pleased to announce that we have designed and are now...

The OBS-3+ Turbidity Monitor is a submersible probe, part of our OBS® line of products that use a backscatter method to measure turbidity. The OBS-3+ operates in the range of 0 to 4000 NTU. It replaces the OBS3 on our pr...

The SI-111 (previously known as the IRR-P) is a precision infrared radiometer made by Apogee Instruments that makes continuous measurements in field conditions. The SI-111 is composed of a thermopile, which measures surf...

The highly accurate ST350 Strain Transducer from Bridge Diagnostics brings great efficiency and reliability to measuring live-load stresses on structures. With minimal surface preparation, you can quickly install the tra...

The NR01 net radiometer is manufactured by Hukseflux for applications requiring research-grade performance. The radiometer measures the energy balance between incoming short-wave and long-wave infrared radiation versus s...

The CNR2 features a unique design with separate outputs for short-wave (solar) and long-wave (atmospheric and terrestrial) radiation. The CNR2 fits in the Kipp & Zonen product line between the single output NR-LITE a...

The NR-LITE is a rugged net radiometer manufactured by Kipp & Zonen. Net radiometers measure the energy balance between incoming short-wave and long-wave IR radiation relative to surface reflected short-wave and outg...

LI190SB accurately measures Photosynthetic Photon Flux Density (PPFD) in both natural and artificial light. PPFD is the number of photons in the 400 to 700 nm waveband incident per unit time on a unit surface. Because PP...

This ISO-second-class pyranometer measures solar radiation with a high-quality blackened thermopile protected by a dome. The blackened thermopile provides a flat spectral response for the full solar-spectrum range, which...
