Waterproof Refractometer Brix
EMS Catalog #72080
Introduction
This refractometer is rugged, waterproof and ideal for field use. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation and automatic shutoff (after 3 minutes). It also features one-button calibration to distilled water and indicates when the battery is low. Powered by a rechargeable, long-life lithium (Li) battery, providing 50,000 tests or about a half year's use on a single charge. Some of its other features include:
- Displays sample temperature followed by measurement result
- IP65 Waterproof, rugged exterior
- Scratch proof sapphire lens
- Long-life rechargeable battery
- Low battery indicator
- AC power adapter
Automatic shutoff
Included
- Refractometer

Power Supply
The meter is powered by one rechargeable lithium-ion battery. The AC adapter plugs into the port on the left side of the meter, providing an alternate power supply as well as recharging the battery. After 3 minutes of non-use, the power will automatically shut off.
Calibration Directions
Note: Use distilled water (refractive index 1.3330 to 1.3340).
- With the meter turned off, place a few drops of distilled water on the lens.
- Close the lid to cover the lens.
- Press POWER to turn the meter on. The temperature of the distilled water appears on the LCD.
- Press and hold CAL for 2 seconds to enter Calibration Mode. "CAL" will be displayed to indicate that it is calibrating.
- When calibration is finished, the meter returns to Measurement Mode and " - - - " is displayed on the LCD.
Note: For best results, calibrate the meter at 20°C. Measurements can be taken at other temperatures, but the calibration should be done at 20°C.
Measurement Directions
After calibration, remove the distilled water from the lens and begin measurement. NOTE: Use a clean, lint-free cloth or tissue to remove solutions from the lens.
- With the meter turned off, place a few drops of the solution being measured on the lens.
- Press POWER to turn the meter on. The temperature of the solution appears on the LCD.
- Close the lid to cover the lens.
- Press READ to view the measurement on the LCD.
- To change scales, press and hold READ for 2 seconds until the scale number changes. Repeat to cycle through the available scales.
- Press READ if desired to repeat the measurement.
