Frying Oil Monitor

Measurement Method

Oil anddeteriorationATAGO
presents
a newstandard inmeasuring oildegradation

Frying oil deteriorates with exposure to air, light, heat, and water.
Depending on how it has deteriorated in quality, it may not justaffect the taste but also be bad for consumer’s health. It is vitalthe oil quality is maintained.

The EU has adopted a value of 25 to 27% as their acceptable upper limit for fats and oils.

② Acid Value ( AV )Easy to read

provides precise
measurements,
regardless of oil
temperature.

Acid Value or AV is an index that denotes the amount of freefatty acids caused by hydrolysis. Many AV test strips, which canbe easily measure the value, are used at food production sites.

③ Carbonyl Value ( CV )It is a measurement denoting the amount of aldehyde andketone produced in frying oils to determine degradation. In
addition, as the threshold is small, it will impact the smell offats and oils greatly.

④ Peroxide Value ( POV )Equipped with apreset AV scale.

Customizable
user scales

Peroxide is generated when oil is exposed to air, causing theunsaturated fatty acids to absorb oxygen. Peroxide value canalso be used to measure hydroperoxide but for frying oil theindicator is by decomposition or polymerization.

Unrivaled High
Performance andValue

It's difficult to determine the value by color

Precise measurements even at high temperatures

Unlike reagents and test strips, the DOM-24 has an easy to read,fully digital display that eliminates any measurement subjectivity orguesswork. The same measurement values can be obtained no matter
who is taking them.

Through ATAGO's advanced technology, the DOM-24 is equippedwith precise and accurate temperature compensation. In contrast toother competitor products, this allows for stable values, even fromhigh temperature samples.

Avoiding burn injuries
Reagents and test strips have a short shelf life
With the DOM-24, there is no need to worry about expiration
dates on reagent kits or test strips, or bother with the proper
disposal of the chemicals associated with titration method.

Approx.

30cm*

Maintain a safe distance between
your hand and the oil.
To improve the safety of employees
and contribute to the reduction in
the risk of burns.

Chemical Disposal

Chemicals are potentially dangerous!?
Unlike titration method or test strips, there is noneed to use a reagent kit with potentially hazardous
chemicals. This eliminates any concerns regarding
chemicals as a food safety issue.

Outsourcing oil titration is costly
and time-consuming. Moreover,furnishing your own facility iscumbersome, requiring special
knowledge and experience. On thecontrary, all it takes to measure with
the DOM-24 is the instrument itself
and minimal training.

Shock-Resistant Design

Equipped with apreset AV scale.

We've made the DOM-24 shock
resistant, just in case it should everbe dropped. Unlike any other similar
instrument on the market, the sensor
section comes with a protective capthat can be removed and washed toensure that it remains hygienic.
