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 eld 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 shuto󰀨.
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.

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 ash)
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 Shuto󰀨
The power will automatically shut o󰀨 if the meter is not
used for 3 minutes.

CALIBRATION
Use distilled water (refractive index 1.3330 to 1.3340)
to calibrate the meter.
1. With the meter turned o󰀨, place a few drops of
distilled water on the lens.
2. Close the lid to cover the lens.
3. Press POWER to turn the meter on.
4. The temperature of the distilled water appears
on the LCD.
5. Press and hold CAL for 2 seconds to enter
Calibration Mode. “CAL” will be displayed to indicate
that calibration is occurring.
6. When calibration is nished 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.
1. With the meter turned o󰀨, place a few drops of the
solution being measured on the lens.
2. Press POWER to turn the meter on.
3. The temperature of the solution appears on the LCD.
4. Close the lid to cover the lens.
5. Press Read to view the measurement on the LCD.
6. 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)
7. Press Read if desired to repeat the measurement.
