A Kestrel meter is ideal for checking studio readings. To get the most out of each session, the temperature and humidity levels within the room must be within a very particular range. The Kestrel DROP D2 with LiNK (bluetooth) is the ideal way to see what the current levels are, and log them throughout a day to see how they may fluctuate. Since the readings are done via bluetooth to a mobile device, studio owners and managers can keep an eye on the levels without ever needing to step foot into the room.
