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. There are two gas connections required,
one to the GAS IN port and the other to the GAS OUT port on the TARGAS-1. This sensor can be used
on Probe Port 1 or 2.

We recommend recalibration of the PAR sensor every 2 years. The temperature sensor should
not require recalibration.
STP-2 Soil Temperature Probe
An optional soil temperature sensor can be used with the TARGAS-1 for
measurement of soil temperature. It is commonly used with the SRC-2 Soil
Respiration Chamber and CPY-5 Canopy Assimilation Chamber. This sensor
connects to Probe Port 1 only.
It is a rugged sensor with electronics housed in an anodized aluminum
enclosure with stainless steel tip.
