Quantum Sensor
Our Quantum Sensor (Apogee) is available for accurate measurement of PAR (Photosynthetically Active Radiation). It is specifically calibrated for use in sunlight conditions. The sensor housing features a fully potted, dome-shaped head, making the sensor fully weatherproof for self-cleaning. Shown with optional leveling unit sold separately.
TRP-3 Temperature/PAR Probe
Our TRP-3 Temperature/PAR Probe can be used for measurement of temperature and PAR. It consists of a rugged, aluminum housing with a black foam cover. A standard tripod thread mount is included for use with commercially available tripods.
STP-2 Soil Temperature Probe
The STP-2 Soil Temperature Probe is available for measurement of soil temperature. Electronics are housed in an anodized aluminum enclosure with a stainless steel tip. This rugged sensor is commonly used with the SRC-2 Soil Respiration Chamber and CPY-5 Canopy Assimilation Chamber.
HydraProbe II (Stevens)
The Stevens HydraProbe II is an all-in-one in-situ sensor that can measure both soil moisture and soil temperature.
For best results, the 3 prongs should be pushed all the way into the ground until the white body of the sensor is flush with the soil surface.
SRC-2 Soil Respiration Chamber
Our SRC-2 Soil Respiration Chamber is available for measurement of closed system soil CO2 efflux. It is constructed out of rugged PVC with a convenient handle for placement on the soil surface. A stainless steel ring provides a good seal on the soil surface or on collars. It includes a temperature sensor for measurement of air temperature near the soil surface.
Optional collars are available from PP Systems.
CPY-5 Canopy Assimilation Chamber
Our CPY-5 Canopy Assimilation Chamber is available for measurement of closed system net canopy CO2 flux. It is transparent and constructed out of rugged polycarbonate with an aluminum ring, which provides a good seal on the soil surface or on collars. It also includes sensors for measurement of air temperature and PAR within the chamber.
Optional collars are available from PP Systems.
Insect Respiration Chamber
Our Insect Respiration Chamber can be used to measure CO2 respiration from small insects.
Sample Injection Kit
PP Systems’ Sample Injection Kit includes a fully-assembled and leak-tested injection port with four spare septa and an absorber column to establish a zero baseline.
The injection port includes a 9 mm low-bleed septum that can withstand up to 50 injections (per the manufacturer’s specification) and a guide hole that will accommodate up to a 22-gauge syringe.
For best results, we recommend changing the septum every 25 injections.
Further customize your system with these built-in options
An optional electrochemical O2 sensor can be installed for measurement of oxygen in addition to CO2.
An optional solid-state H2O sensor can be installed for accurate measurement of humidity.
WiFi can be integrated for remote real-time monitoring.
