How To Use A Refractometer For Glycol

December 3, 2020

This is a small device that is able to determine the freezing point of propylene glycol and ethylene glycol antifreeze solutions. The heat transfer fluid is 50% dowfrost hd (propylene glycol) at 40°f.

A hydronic heating or cooling system is one of the most efficient types of systems when it comes to providing comfort for a building.

How to use a refractometer for glycol. We have two different types of refractometers that you can use to measureglycol concentration in water. Extremely easy to use, precision instrument for measuring the concentration of glycol antifreeze. Suitable for testing / analyzing the glycol concentration of engine coolants and antifreeze solutions, such as mono propylene glycol or mono ethylene glycol.

The refractometer has an adjustable eyepiece. The potential exists for the glycol concentration to be less than design. ≡ glycol tester ∼ refractometer:

How to use a refractometer to test glycol concentration. Moreover, how do you use a glycol refractometer? It only takes a few drops of solution to use and it is very user friendly.

The first is the misco 7084vp+ glycol & battery tester. The glycol concentration is known because the system fluids were purchased premixed with deionized water (di water) from go glycol pros. To calibrate, just make sure the prism is clean and place a few drops of tap water on the prism.

Read from the appropriate side of the scale (ethylene or propylene glycol. Point the instrument at a light source when taking the reading. Just place a few drops of fluid on the prism and hold the unit up to a light source.

Calibrate the refractometer with a standard solution before use. A refractometer can be used to measure things like the total plasma protein in a blood sample, the salinity of water and even the amount of water content in honey. • sampling technique is critical in hydrometer use.

Clean the instrument after each use. Its characteristics are small and light; Look into the eyepiece and read the scale.

The scale is calibrated for use at 20±2¡c with the graphs provided. Please view the below video on how to test your system with a refractometer. The sample is place on a cover plate and a prism and then held to the light to view the scale inside the meter.

It is a traditional analog refractometer with scales for measuring both ethylene glycol (eg) and. The process takes only a few minutes to carry out and an accuracy of about ±0.5% alcohol can be obtained using reasonable care in ensuring that both readings are made at the same temperature. Misco.com manufactures a refractometer designed for testing glycol based antifreeze.

Calibration and use of analog refractometers. Increase accuracy by using a refractometer. If this is not possible, correction charts may be used.

September 13, 2015 newsletter dynalene. Use enough fluid to cover the entire measuring prism. Be sure the instrument is clean and dry before use.

Propylene glycol cannot be read with a hydrometer due to the fact that up to 70% concentration specific gravity increases, but above 70% specific gravity decreases. The hi96832 digital refractometer utilizes the measurement of refractive index to determine the percent volume and freezing points of propylene glycol based solutions. A 100% solution reads identical to a 40%.

Propylene glycol is used in glycol chillers and dispensing systems intended for food applications, such as beer and wine. In a system with diluted glycol, we can see an undesired performance, a reduction of corrosion inhibitors, and (for colder climates) a reduction in freeze/burst protection. Since the reading will be affected by temperature changes, it is best to calibrate at the temperature of the test environment.

Is measured in the usual way with the hydrometer jar. If the user normally wears spectacles, it may be that the scale is sharper without them. A refractometer is fast, convenient, and easy to use.

Ethylene refractometer and propylene glycol refractometer: A refractometer is a tool used for measuring concentrations of aqueous solutions.it has many applications across food, agricultural, chemical, and manufacturing industries. • hydrometers only work for ethylene glycol based coolant/antifreeze.

This glycol fluid refractometer is a precise optical instrument that measures the concentration of aqueous solutions by measuring its refractive index. Thanks to the serviceability of the major components, a building owner can maintain their system for optimal efficiency and system life. 1.what is a refractometer for glycol?

Only a few drops of sample are needed to make the refractometer reading, while the s.g. If concentration is unknown, we recommend you use a refractometer to measure current glycol concentration. Here are a few do’s and don’ts for the proper use of this instrument.
