ST-137 Edible oleic acid peroxide value meter
The ST-137 edible oil peroxide value acid value detector is
designed and manufactured based on the titration method in the
GB/T5009.37 hygiene standard for edible vegetable oils. It can
quickly detect the peroxide value and acid value content in edible
oils (such as soybean oil, sesame oil, peanut oil, corn oil, etc.),
and is in compliance with the testing methods for acid peroxide
value in edible oils such as GB 15680-2009 palm oil, GB1535 soybean
oil, GB/T 1536-2021 rapeseed oil, GB/T8233-2018 sesame oil, GB/T
23347-2021 olive oil, GB/T 19111-2017 corn oil, GB/T22479 Sichuan
pepper seed oil, etc.

● Data Upload: Supports data transmission through network ports and
WiFi, as well as receiving and uploading detection tasks for
various regulatory platforms;
● Data analysis: Data analysis and statistics can be conducted
based on testing items, testing samples, etc., and a certain period
of time or total testing volume can be selected for qualification
rate analysis, which can be visually displayed in the form of pie
charts, bar charts, and line charts. At the same time, daily
testing volume and other information can be calculated;
● Data export: The detection results are automatically generated
into two types of tables, Excel and TXT, and can be copied to a USB
drive;
● Channel module: Independent detection unit, each unit consists of
a set of light source system, a sample chamber, and a set of
detection system.
● Sample information: The detection channel can independently set
sample information (sample name, sample source unit name, address,
phone number, responsible person), testing personnel information
(testing unit, inspector), etc;
● User settings: User information can be set with the name and
address of the testing unit (three-level linkage), contact phone
number, responsible person, and auditor. Multiple accounts can be
set, and sample source settings (sample source, source address,
responsible person, contact information, credit code, etc.) can be
added;
● Project Update: Supports remote updates for detection projects
and systems, with new versions automatically updated;
● Printing function: Built in 58mm thermal printer, with three
printing modes (standard printing, merged printing, simplified
printing) to choose from. The printed test report includes
information such as test items, sample names, test limits, test
results, result judgments, testing units, tested units, inspectors,
responsible persons, auditors, testing dates, etc;
● About us: Each device has an independent factory number including
(product number, product name, model, production date,
manufacturer, manufacturer website, manufacturer phone number,
current version).
