## Questions & Answers

**Q: Does this product have certified NIST**
A: 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.

**Q: 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**
A: 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.

**Q: The equipment can be calibrated with 407722 ??? (Sound)**
A: 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.

**Q: Is the 9 volt battery replaceable?  Does it have a tripod mount?**
A: Yes the battery is replaceable however it is a 3V #2032. To my knowledge no tripod mount is available.
