5-Scale Digital Refractometer

The PEAK digital refractometer meets or exceeds the requirements for refractometers in international standards ASTM D7821 and ASTM D3321.

• Easy To Use: Simply place a drop or two of fluid in the stainless steel well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout and ensures that fluids are measured accurately. The user interface consists of two buttons, one to take readings and the other to step through various menu options.
• Easy To Read: The large backlit LCD display is easily read, even in dim light, and removes the subjectivity associated with interpreting where a boundary line crosses tiny scale divisions.
• Easy To Calibrate: Calibration is automatic and does not require the use of special calibration solutions, or tools. The 5-scale Digital Refractometer automatically calibrates itself to water and is ready to use in seconds. No more screws to turn and nothing to adjust.
