LH-T55 digital refractometer is a high-precision optical instrument designed with the principle that different liquids have different refractive indices. It has the characteristics of beautiful appearance, convenient carrying, easy operation, fast detection, and accurate results. A must-have for work. Quickly detect sugar content in fruits, vegetables, freshly squeezed juices, beverages, food processing industries and honey.
Model No LH-T55
Measurement range 0-55%
Accuracy 0.2%
Testing Time 3S
Weight 52x44x154
Before the testing
1, The instrument and liquid test sample should be placed in same environment temperature.( the difference of the temperature between environment , instrument and liquid test sample should be in 2 degrees)Otherwise it will affect the accuracy of the testing.
2, Shake the liquid test sample evenly when the testing
3, If the instrument hasn’t be used for a long time, resetting the “Zero point” before using.
4, Check the power of the battery. The low powder will affect the accuracy of the testing.
Operation
Power on
Press and hold the “On|Off/Read” for one second, until the screen display.
Power off
Press and hold the “On|Off/Read” for one second, until the screen display “ Power off”.
Operating steps:
1. Open the shading plate counterclockwise.
2. Use the pure water to clean the detection slot with soft cloth, then remove the residual water.
3. Add 3-5 drops of liquid test sample to the detection slot.
4. Closed the shading plate clockwise.
5. Press the “On|Off/Read”shortly, or touch the “touch instruction point”. The screen shows the value of BRIX. Press the “Zero” shortly, The screen will show the value of Refractive index.
Instruction of power charging
1, Plug the data cable into the interface at the bottom of instrument, Plug the other end into charging power in 5v.
2, When the charging light turn red, mean the instrument is charging.
3, When the charging light turn green, mean the power charging is finished
