-
Is the Avocado Quality Meter waterproof?
-
The Avocado Quality Meter is not designed to be waterproof and should not be used underwater. The Avocado Quality Meter is designed to be water-resistant. Use in light rain is fine, however, there are electronics inside of the Avocado Quality Meter that can be damaged from water entering the instrument, so it is not recommended to use the Avocado Quality Meter during heavy rainfall.
-
What are the operating conditions of this product?
-
The recommended operating temperature range for the Avocado Quality Meter is 0 – 50° Celsius.
-
Does the Avocado Quality Meter work on small avocados?
-
The model was built using size 36 to 48 avocados. Due to NIR transmittance, the pit of smaller avocados are more likely to interfere with dry matter measurements. We do not know the avocado size cutoff, but for the most accurate measurements we recommend that the avocados fall within the range that the model was built on.
-
Do I need to build my own avocado model?
-
No! The Avocado Quality Meter is preloaded with a robust model and fully calibrated when it leaves out production facility.
