Features
The measurement is based on the supercooled mirror principle, which eliminates errors caused by the inertia and lag of the system and ensures direct and accurate measurement of the actual temperature.
The system is stable and does not require repeated calibration.
Built-in electronic flow meter to monitor the flow rate of the injected gas.
Use "USB data line output" and "RS-232 data line output" to communicate with PC.
