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.

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.

can i buy the probe seperatly

Unfortunately, you cannot purchase the probe for this unit separately. If you change the probe on the meter, it will no longer provide accurate readings. The meter is calibrated with the probe at the factory to provide accurate reading, and the meter can only be calibrated with one probe at a time. If the probe is damaged, you will have to send the meter in to the factory to have a new probe calibrated with the meter.
