The PGTEMP-PROBE from DSC is a temperature probe accessory for the DSC PG9905, PowerG Temperature Sensor. Attaching the probe to the PG9905 allows the sensor to monitor areas that it otherwise could not, such as the exterior of a building or a walk-in freezer. The PG9905 cannot be mounted in areas with extreme temperatures or outside where it would be exposed to the elements. The probe is 11.4' long and has an operating temperature range from -22°F to 140°F (-30°C -+ 60°C).
