INTRODUCTION
Housed in a protective rubberized IP65 Waterproof case to safeguard the electronics from wet environments and makes for easy clean ups Model 300058 features a scratchproof sapphire lens.Measure samples as small as 1 ml, in the field with laboratory accuracy. Sample temperature is initially displayed on the large LCD followed by the measurement results. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation and automatic shutoff.
Powered by a rechargeable, long-life, Li (Lithium Ion) battery providing 50,000 tests on a single charge.Simple one-button calibration using distilled water ensures accurate readings.
MATERIALS SUPPLIED
- Refractometer
- One lithium-Ion battery
- DC Power Adapter
- Distilled Water
- Transfer pipet
- Instruction Manual
- Carrying Case
FEATURES
- Displays sample temperature followed by measurement result
- IP65 Waterproof, rugged exterior
- Rechargeable battery
- Low battery indicator
- DC power adapter
- Automatic shutof
POWER SUPPLY
The meter is powered by one rechargeable lithium-ion battery. An icon in the upper-right corner of the LCD indicates the level of battery power available:
75%-100% power
40%-75% power
15%-40% power
Less than 15% power. (This icon will flash)
The DC adapter included plugs into the port on the left side of the meter. This both provides an alternate power supply and recharges the battery.
Automatic Shutoff
The power will automatically shut off if the meter is not used for 3 minutes.
FRONT PANEL DESCRIPTION
- POWER – Power on/off
- READ – Read measurements /select scale
- CAL – Calibrate meter
- LENS COVER
LCD DISPLAY
- S 1 – Current scale number
- BATTERY ICON – Battery power level
- DISPLAY – Displays temperature and readings
CALIBRATION
Use distilled water (refractive index 1.3330 to 1.3340) to calibrate the meter.
- 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 calibration is occurring.
- 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 PROCEDURES
After calibration you can 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. (see page 10)
- Press Read if desired to repeat the measurement.
MEASUREMENT ERRORS
Certain conditions can cause an error code to appear on the LCD:
Error Code & Cause
HHH The measurement is above the upper limit
LLL The measurement is below the lower limit
