CEM DT-70 IP68 Deep Frying Oil Quality Tester

The CEM DT-70 is a rugged, IP68-rated digital deep frying oil tester designed to help restaurants, commercial kitchens, food processing plants, and quality control laboratories monitor the condition of their cooking oil in real time. The device measures Total Polar Materials (TPM%) — the industry-recognized indicator of oil degradation — together with the actual oil temperature, so operators can tell at a glance whether the oil is still safe to use or needs to be changed.

Built with a durable stainless steel probe and a fully sealed, waterproof and dustproof IP68 housing, the DT-70 is engineered to withstand the demanding, splash-prone environment of a commercial fryer station while delivering fast, stable, and repeatable readings. By taking the guesswork out of oil changes, the DT-70 helps businesses maintain consistent food quality and safety, meet regulatory TPM limits, and avoid the unnecessary cost of discarding oil too early — or the risk of using oil that has degraded too far.

Uniglobal Business supplies the CEM DT-70 to commercial kitchens, QSR chains, hotels, catering operations, and food safety inspectors who need a dependable, easy-to-use instrument for daily frying oil quality checks.

Frequently Asked Questions

Q1. What does the CEM DT-70 actually measure?

The DT-70 measures two things at once: the Total Polar Materials (TPM%) content of the frying oil, which indicates how degraded the oil is, and the current temperature of the oil.

Q2. What is TPM and why does it matter?

TPM (Total Polar Materials) is the internationally recognized measure of how much a frying oil has broken down through repeated heating. As TPM rises, oil quality, taste, and food safety decline, so monitoring TPM tells you exactly when the oil needs to be replaced instead of guessing by time or appearance.

Q3. Is the DT-70 safe to use directly in hot oil?

Yes. The stainless steel probe is designed for direct insertion into hot frying oil, and the IP68-rated housing protects the internal electronics from heat, splashes, and moisture during use and cleaning.

Q4. How accurate is the DT-70?

The device offers a TPM accuracy of ± 2% and a temperature accuracy of ± 1.5°C, which is well within the standard required for reliable commercial kitchen and food safety monitoring.

Q5. Can the DT-70 be used with any type of frying oil?

Yes. It is suitable for common frying oils including vegetable oil, palm oil, sunflower oil, and soybean oil, making it versatile for most commercial and industrial frying applications.

Q6. How do I clean and maintain the device?

Thanks to its IP68 rating, the DT-70 can be rinsed under running water after use. Wipe the probe clean after each test and store the unit in a dry place; periodic calibration is recommended to maintain long-term accuracy.

Q7. Who typically uses the CEM DT-70?

It is widely used by restaurants, hotels, QSR chains, catering businesses, food processing plants, and food safety inspectors who need to routinely verify frying oil quality and comply with food safety standards.
