Does this product have certified NIST

No, Extech does not offer NIST calibration on the EN300. Most products are available with NIST at an additional cost, but the EN300 is not available w/NIST.

What is the minimum wind speed that this anemometer can measure accurately? I'm currently looking for an anemometer that can measure wind speed <1 m/s

wind speed measurement for the 407113 CFM Anemometer is: MPH: 1.1 to 78.3 knots: 1.0 to 68 km/h: 1.8 to 126 AIRFLOW: CFM = FT3/MIN: 0 TO 999,900 CFM CMM= M3/MIN: 0 TO 999,900 CMM I hope this helps your decision to buy.

The equipment can be calibrated with 407722 ??? (Sound)

This meter can use the 407001 software via the PC interface to view the parameters in real-time on the PC. You cannot log all 5 parameters at the same time. You can use the 407022 to calibrate the sound level mode. I hope you find this information helpful.

Is the 9 volt battery replaceable? Does it have a tripod mount?

Yes the battery is replaceable however it is a 3V #2032. To my knowledge no tripod mount is available.

Très satisfait

Bonne qualité de construction et extrêmement facile à utiliser, il y a les 5 mesures et une fonction Min/Max, basta. Personnellement ça me vat. Concernant la mesure sonore j'ai obtenue 27dB dans un quartier très calme la nuit. Même si en deçà des 35dB minimum mesurable spécifié on est plus garantie Classe 2 ça semble être assez précis quand même. Concernant la mesure de température il y a une sonde interne et une prise Type K juste sous l'anémomètre. Sonde Type K fournie. Une sacoche, une boule micro noire et 6 piles AAA sont aussi fournies.
