The 5 Best optical Density meters (2023 reviews)

The agriculture solutions optical density meter's material feels more premium than its price would suggest. The Alcohol Refractometer is Easier & Quicker than Proof & Trailes Hydrometer. It is made with a very sleek design. It can only measure dissolved sugar in a solution. This works great for beer wine or moonshine.

For this refractometer is equipped with an automatic temperature compensation system, once calibrated, the change of working temperature within +/-30 degree centigrade wouldn't effect the accuracy of reading result. It does not display proper alcohol content even in water. It is good for quick result with small sample requirements. It is easy to use, and it makes a hydrometer (alcohol type not spg) almost very old school.

Why We Like This:

Alcohol level displayed on a scale like a old fashioned mouth thermometer
Delivers what they promise

Best Runner up: Vee Gee scientific optical Density Meter

Buy on Amazon

We are personally inclined towards vee gee scientific optical density meter, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. The analog brix scale features a bright, high. It is easy to read, bright scale and pre-calibrated right out of the box. It comes with a zippered vinyl carrying case, a plastic transfer pipet and an instruction manual. It is made with plastic and a screw adjustment for calibration. It is used for continuous process monitoring and data readouts, and are generally fitted into a piping system for ongoing analysis.

The temperature compensation feature is very nice and ensures precise readings. It is heavy duty because there is a difference in the quality of the quality.

Why We Like This:

Calibrated and can be calibrated with distilled water
Contrast display for clear visibility of the boundary and memory lines intersection
Delivers what they promise

Best For liquid: Apera Instruments optical Density Meter

Buy on Amazon

This DO meter is built with an optical DO sensor which does not consume oxygen when testing in liquid, meaning it's much easier to use and provide more consistent and accurate readings than conventional DO meters. It allows use as a benchtop meter. The light sensor does not consume oxygen to get its measurements which eliminates a significant flaw in the original meter designs. The special coating on the luminescent cap makes it anti-interference and unaffected by light and chemicals.

This device's only purpose is to tell the Dissolved Oxygen levels in watery solutions with the temperature using optical light technology. It is critical to clean the probe (and metallic parts) and meter with some denatured alcohol and ensure the meter kit is stored outside of any briny air when not in use. The large temperature difference will make the reading stabilization take longer.

Why We Like This:

Calibration for saturated air and zero-oxygen
Need for solution refill or frequent membrane change
Membrane or solution needed for the optical probe

Best For All Graphic Arts film applications: VTSYIQI optical Density Meter

Buy on Amazon

Next on the list, we've got yet another meter that manages to win our hearts. It's the vtsyiqi optical density meter and it's widely considered as one of the best convenient meter you can buy. It measures the optical density and light transmittance at the same time, mainly for the following three types of product measurement. It can only be used to test translucent materials details. It is ideal for all graphic arts film applications, from quality control to calibration.

Why We Like This:

Independent power supply or light source required
All graphic arts film, measuring absolute optical density and relative density and dot area
All kinds of milky white, fog material, measuring light transmittance

Best Premium: Vaetuka optical Density Meter

Buy on Amazon

Vaetuka optical density meter is the epitome of what a great meter should be. It is easy to calibrate using plain water and the calibrate button. It is easy to load liquid to be tested. It can be used about 2000 times in one full charge. It includes the small sample cup is easy to clean and, as mentioned, a cleaning cloth. It is easier to see regardless of the traditional sugar gauge, and the temperature can be measured at the same time.

It is that it is a compact size that can be measured with one hand and easy to carry. It can not adjust for decinal places. It comes with a lithium battery, it can be charged from the charging port, and does not require replacement of batteries.

Why We Like This:

Screen display and quickly get data
Active in a wide range of purposes
One of the new comers and featured product
