I have one of your Maple Syrup Palm Abbe refractometers and was wondering if it is possible to add an additional scale for reading invert sugars by percent. And if so how much would it cost for you to add the scale to my device?
Thank you for purchasing the Palm Abbe digital refractometer for measuring maple syrup. You can add additional measurement scales to a Palm Abbe refractometer depending on the base Palm Abbe model that you have. All Palm Abbe refractometers that begin with model # PA201 can only contain a single scale. All Palm Abbe refractometers that begin with model # PA202 can contain up to two scales. All Palm Abbe refractometers that begin with model # PA203 can contain up to five scales. If you send your Palm Abbe refractometer back to us we can reprogram it for a fee. Reprogramming charges apply to scale changes and scale additions. We have several scales for invert sugar.
