Antifiriz ve Akü Sıvısı Testi için Refraktometre

 RT-01 Refractometer for Anti-freeze & Battery Fluid testing
RT-01 is a Refractometer for Anti-freeze & Battery Fluid testing
Specifications:

Range: -50 to 0ºC propylene & ethylene glycol 1.15 - 1.30 specific gravity
Minimum Scale Division: 5ºC
Automatic Temperature 
Compensation range:  10 to 30ºyapıC

NOTE - Read Warnings & Maintenance before proceeding

1. Use dropper to obtain coolant sample, open the cover plate & place 2-3 drops of the sample onto the prism surface, close the cover plate, press lightly & ensure the water spreads evenly across the whole surface area without air bubbles or dry sections. (wait 30seconds until the liquid sample adjusts to ambient temperature).
2. Hold towards light source & look into the eyepiece to view the scale, the coolant readings are located on the far left & right & the battery fluid reading is in the centre.
3. The test reading is taken from where the boundary line between the upper blue field & the lower white field, crosses the graduated scale. This reading is the actual freezing point/concentration level of the coolant or the charge state of the battery fluid.
4. Wipe the prism clean & dry with damp soft cloth & store in the supplied case.

1. Open the cover plate & place 2-3 drops of distilled water onto the prism surface, close the cover plate, press lightly & ensure the water spreads evenly across the whole surface area without air bubbles or dry sections. (wait 30seconds until the water adjusts to ambient temperature)
2. Hold towards light source & look into the eyepiece, if the boundary line between the upper blue field & the lower white field is not located exactly on the 0o C waterline, adjust the correcting screw until both lines meet.
3. Wipe the water from the prism with clean dry cloth & replace the rubber correcting screw cover. 

NOTE: under normal operating conditions the calibration only needs to be checked periodically.

MAINTENANCE

1. If the ambient temperature is not within the automatic temperature compensation range 10 – 30ºC, the instrument must be calibrated before testing commences.
2. The prism must be cleaned thoroughly with a soft, clean damp cloth after each use – failure to do so will result in inaccurate readings & possible long term damage.
3. The instrument must be kept in a dry clean environment to prevent condensation forming on the optical components.
4. Use a glass rod to sample battery fluid as acid will damage the dropper & also harm your skin–separate readings must be taken from each cell.
