Reichert 13940015 Multi-Chek digital refractometer can help users measure the refractive index of liquids with utmost accuracy and precision. It is useful in automotive applications for checking coolant, battery and windshield fluids.
Features:
- Reichert 13940015 digital refractometer includes a coolant tester that checks engine coolant freeze point EG and PG concentration.
- Its automatic temperature compensation (ATC) delivers immediate, accurate and direct readings at ASTM D3321 standards of +/-1 degrees F and +/-0.55 degrees C.
- This Multi-Chek refractometer's battery fluid tester conducts fast and easy tests of battery electrolyte, specific gravity and condition.
- It can check the freezing point of windscreen fluid with a simple push button test.
- This Multi-Chek instrument allows the user to switch between Celsius and Fahrenheit temperature units.
- This digital refractometer has an IP65 rating, which makes it dustproof and resistant to low-pressure water jets from any direction.
Frequently Asked Questions:
Q. How to setup Reichert 13940015 digital refractometer?
A.
- Insert the included batteries with the positive side (+) facing outwards.
- Align the small mark on the battery cover with the mark on the instrument body, then insert the cover.
- Rotate the cover clockwise until it reaches the desired position.
Q. When should you clean this digital refractometer?
A. Clean the measurement surface and well immediately following each sample reading.
Q. How should I clean the measurement surface and sample?
A. Cleanse with a mild soap and water solution or isopropyl alcohol, then rinse with distilled water.
Q. How do I clean the body of Reichert 13940015 digital refractometer?
A.
- Use a soft cloth and a mild cleaning solution, such as a window cleaner.
- Then, wipe the instrument dry.
Q. Are there any cleaning precautions I should be aware of?
A.
- Avoid using harsh cleaning agents that could damage the instrument.
- Do not use strong solvents, as they may deteriorate the prism seal and damage individual components.
Q. How do I calibrate Reichert 13940015 digital refractometer?
A.
- Apply distilled water to the measurement surface.
- Allow distilled water sample to temperature equilibrate with the instrument.
- Press and hold the CAL key until CAL is displayed.
- While holding CAL key, press the READ key.
- Release both keys.
- Successful calibration indicated by END display.
Q. How to change the fluid measuring type on this unit?
A. Press SCALE and then toggle between DOT4, DOT4 PLUS, EG FP, EG %, AdBlue%, Windshield washer fluid FP and Batt SG to change the reading mode scale.
Q. How does automatic temperature compensation work?
A.
- Automatic temperature compensation is a process that adjusts readings for temperature changes. For example, if a sample is taken at a temperature outside the normal range for the instrument, the reading is corrected to a reference temperature of 20°C. This is important because the refractive index of a substance changes as the temperature changes.
- It is worth noting that temperature compensation is not a substitute for controlling the temperature of the sample and the measuring surface. For this feature to work effectively, it is necessary to allow the sample to equilibrate to the ambient temperature of the measuring surface. Failure to do so will result in less accurate readings since the sample will be in a state of temperature and refractive index change.
