ST-138A Edible Oil Refractive Index Meter
ST-138A edible oil refractive index meter accurately measures the refractive index of oil esters, which can identify whether the oil is adulterated. This method is a routine method for quality and technical supervision departments to identify the quality of oil, and is currently the fastest screening method. It is suitable for the supervision of edible oil quality (including rapeseed oil, peanut oil, soybean oil, palm oil, blended oil, and various salad oils) in the circulation field, especially for the supervision and testing of bulk oil quality.
Product Features:
The LCD display screen directly displays the test results, compact and portable, with a handheld design, suitable for on-site testing;
Equipped with automatic zero adjustment function, no need to use any chemical reagents;
Digital display, high detection accuracy;
Improve structural design to avoid external light interference.
