Resolution: 0.1°C (0.2°F)

Field of View : approx 12:1

Response Time : approx 0.5 s

Accuracy : ±2°C (4°F) or ±2% of reading – a needle valve and a reverse free-flow

check valve connected in parallel.

– It restricts the flow rate in one direction

– While allowing the air to flow freely in the other direction.
