Accurate within ± 1.5 kPa across a pressure range of 15 to 115 kPa (4.43 to 34.96 in Hg). Long-term non-stability has been measured continuously indoors and in natural conditions (with sensors mounted inside a datalogger enclosure) for multiple sensors and is less than 0.5 % per year. Temperature effects on signal are less than 1 % across a wide temperature range (-20 to 50 ...

Chlorophyll meters typically output an index that isnon-linearly related to chlorophyll concentration (e.g.,CCI or SPAD). The MC-100 outputs an estimate of actualchlorophyll concentration in units of μmols per m² of leaf surface. Thus, changes in the displayed output reflect true changes in chlorophyll concentration. For example, doubling a measured chlorophyll concentration represents an actual ...

Net radiation is the sum of the four components shown to the left (incoming shortwave, outgoing shortwave, incoming longwave, outgoing longwave). Incoming shortwave incident on the surface is either reflected or absorbed by the surface material, and longwave radiation is emitted from the surface and emitted from the molecules of air in the atmosphere. Typical clear sky summer fluxes over grass ...

Apogee photometric sensors use a photodetector with a spectral response that closely matches the sensitivity of the human eye to light; sensors include a diffuser to properly weight light incident from any angle. Apogee photometric sensors provide highly accurate illuminance measurements (lux or foot candles) at an affordable ...

Many plants are affected by interruptions in dark periods even by extremely dim light. Apogee’s new Quantum Light Pollution Sensor is designed to detect photons from 340-1040 nm that are below the sensitivity level of a typical quantum sensor. Detecting stray photons that disrupt the night is critical in preventing negative effects in plants such as plant hermaphrodism and stunted growth. The ...
