Model SD-5P & SD-6P - Stem Micro-Variation Sensors
SD-type sensor is a highly precise incremental LVDT-based sensor for monitoring micro-variations of stem diameter in micron range. Plant growth and water balance affect diurnal behavior of stem diameter. The growth rate depends on a vegetation stage and environmental conditions. The diurnal variations represent mostly fluctuations of water content in plants. Two ...

Model DE-1P - Dendrometer
The DE-1P Dendrometer is a highly precise incremental LVDT-based sensor for monitoring micro-variations of trunk radius in micron range. Plant growth and water balance affect diurnal behavior of trunk radius. The growth rate depends on a vegetation stage and environmental conditions. The diurnal variations represent mostly fluctuations of water content in plants. Two ...

Model FI-LM, FI-MM & FI-SM - Fruit Growth Sensors
A series of absolute displacement sensors provides recording both size and growth rate of intact rounded fruits in three diameter ranges within 7 to 160 mm. Two phenomena affect fruit diameter. These are growth and internal water content. The growth component is usually dominant. At the same time, in some cases, the fruit may loose water that is manifested in deceleration of growth rate ...

Model FI-XSP - Extra Small Fruit Growth Sensor
The FI-XSP absolute displacement sensor provides recording both size and growth rate of intact small rounded fruits within 4 to 30 mm in diameter. The FI-type sensor consists of an LVDT transducer with a hanging spring, and a DC powered signal conditioner. Standard cable length between sensor and signal conditioner is 1 meter. The probe is connected by a standard 1-meter cable to the waterproof box with the signal conditioner inside. Standard output cable ...

Model LT-1P - Leaf Temperature Sensor
The LT-1P sensor is a subminiature touch probe that measures absolute temperature of a leaf. The lightweight stainless steel wire clip holds a high precision glass encapsulated thermistor, which is about millimeter in diameter. Small size of the probe and its special design provide almost negligible disturbance of the natural leaf temperature. The thermistor is connected to the clip ...

Model SF-4P & SF-5P - Sap Flow sensors
The SF-4P and SF-5P sensors are designed for monitoring relative variations of sap flow rate in a leaf petiole or small shoot. The sensor’s probe is made as a hollow collapsible heat-insulating cylinder. A heater and a pair of bead thermistors are located inside the cylinder. A signal conditioner provides powering of the heater and conditioning of the output signal. The probe is connected by a standard 1-meter cable to the waterproof box with the ...

Model PIR-1M - Quantum Sensor
The PIR-1M Quantum Sensor measures Photosynthetic Photon Flux (PPF) in µmol·m−2·s−1. The sensor is cosine-corrected, and has a domed diffusion disk and head for improved self-cleaning characteristics and long-term stability. The cosine error for typical applications is less than 2%. The output increases ...

Model TIR-4P - Pyranometer
The TIR-4P Pyranometer measures total irradiance in Watts per square meter. The pyranometer includes a temperature compensated silicon detector equipped with the cosine-correcting head. The spectral response of TIR-4P Pyranometer does not cover the full range of solar spectrum. Therefore, it should be used under the same conditions as at calibration. All ...

Model PTM-48A - Photosynthesis Monitor
The PTM-48A Monitor is truly state-of-the-art system for long-term automatic recording physiological characteristics of intact plants. The Monitor has four inputs for original automatic self-clamping leaf chambers. The chamber is normally open and shuts the leaf only for 30 seconds to take readings of both CO2 and H2O exchange rates. The short measurement time provides minimal disturbance of natural leaf conditions. The standard LC-4B Leaf Chamber has a ...
