nothing fancy
Not a fancy meter but it does what you need it to do. The unsung hero for me and my most used meter. Measures the temp and velocity and can calculate the CFM. Bread and butter tool.

Works great
Been using this product for a while. Recently replaced the vane on it as I've dropped it one time too many! Still works great wit the replacement vane. Manages to get a lot of measurements i need for most of my work. Wet bulb, temp, volume. Couldn't make money without it.
