This device is a Digital Deep-Frying Oil Tester / Quality Monitor CEM DT-70, . It measures the thermal degradation of frying oils and fats directly in hot oil.
Core Functions
TPM (Total Polar Materials) Measurement: Evaluates oil quality and aging caused by heat and oxidation. As frying oil breaks down, polar materials increase; this meter quantifies that degradation to signal when oil should be changed.
Dual Temperature & Quality Display: Shows both the current oil temperature (in °C or °F) and the %TPM value simultaneously on the backlit screen.
Color LED Alarm Indicator: Features a traffic-light LED alert system (Green/Yellow/Red) to quickly notify the operator:
Green: Fresh, usable oil.
Yellow: Critical/Aging oil; replacement recommended soon.
Red: Expired oil exceeding safety limits (%TPM > 24%); immediate oil change required.
