Reagent Meter It is a widely used measurement tool in the food industry. It is useful to measure the concentration of a solution such as

The amount of sugar in the juices of fresh fruits, syrups, and drinks, such as the values ​​​​in degrees Brix (percent weight to weight).

How to measure This is done by dropping the desired solution onto the prism. Closed with cover Then look through the channels in the light. It is visible as a color band. Read the numerical values ​​​​on the scale defined by the machine, such as percent concentration. The sugar syrup is measured in brix degrees or liquid density. Or both

⇛ Before and after using a hand refractometer Clean the prism. This is where the sample solution drops. With lens paper, dust, dirt on the prism. It affects the accuracy of the readable values

⇛ When drop solution should not have bubbles. This may affect the readability. The readings are relative to the concentration at the specified temperature

⇛ The readings are relative to the concentration at which the temperature specified in the machine is 20°C.
