Safety
• Store your product in a clean, dry place.
• Do not immerse in or clean under running water.
• Do not drop or subject to shock or excessive force as it may result in damage
to the mirror tube &/or optical components.
• Do not scratch the prism surface.
• Do not attempt to measure corrosive chemicals as it will damage
the instrument.
• The prism must be cleaned thoroughly with a soft, clean damp cloth after
each use - failure to do so will result in inaccurate readings and possible long
term damage.
When using the Baker B3090 – use extreme care when opening the radiator
cap – do not remove while engine is running or if engine is warm. Do not
let battery fluid come into contact with skin or eyes which may cause
personal injury.
IT IS STRONGLY RECOMMENED TO WEAR SAFETY GLASSES AND
GLOVES WHEN OBTAINING SAMPLES OF ENGINE COOLANT OR
BATTERY FLUID.

Operating Instructions
Initial Calibration
1. Open the Cover Plate and clean the surface of the Prism with the included
Cleaning Cloth
2. Apply 2-3 drops of distilled water onto the prism surface, close the cover
plate and press lightly ensuring that the distilled water spreads evenly;
eliminating air bubbles while allowing it to rest for approx. 30 seconds.
3. Aim the front end of the refractometer towards the direction of a bright light
and adjust the Eyepiece until the reticle is clearly visible.
4. If the boundary line does not intersect at the lowest end of your
corresponding scale, turn the scale calibration screw until adjusted.
5. Wipe the water off the Prism and Cover Plate with a moist cotton cloth and
store the calibration adjustment plate.
NOTE:
While under normal operating conditions, the calibration only needs to
be verified periodically.
Measuring Procedure
1. Open the Cover Plate and clean the surface of the Prism with the included
Cleaning Cloth.
2. Apply 2- 3 drops of the liquid sample onto the prism surface, close the Cover
Plate and press lightly ensuring that the sample spreads evenly; eliminating
air bubbles while allowing it to rest for approx. 30 seconds.
3. Aim the front end of the refractometer towards the direction of a bright light
and adjust the Eyepiece until the reticle is clearly visible.
4. Read the measurement value corresponding to your scale where the
boundary line intersects the scale.
5. After testing, wipe the sample off the Prism and Cover Plate with a moist
cotton cloth. Allow to air dry before storing away.
Automatic Temperature Compensation (ATC)
Baker Refractometers include automatic temperature compensation to
automatically adjust for any temperature variance between 32°F to 86°F (0°C
to 30°C).
