China TSTcheck oil test companies provide specialized solutions for testing various oils such as frying oil, lubricants, and transformer oils. Leading manufacturers like Jilin Test Bio-Electron Co., Ltd. and other Chinese suppliers offer test strips and portable analyzers to quickly measure critical parameters. Wrindu, a Shanghai-based company, complements these products with advanced high-voltage oil testing equipment for utilities and industrial applications.
What Does TSTcheck Oil Testing Involve?
TSTcheck oil testing typically involves using test strips or portable analyzers to measure parameters such as total polar compounds (TPC), acid value, moisture content, and color in oils. The process is designed for rapid, on-site assessments, typically taking around 30 seconds. This testing is vital for ensuring oil quality in food processing, industrial machinery, and high-voltage systems. Suppliers like Wrindu offer these products, along with advanced tools for dielectric breakdown voltage (BDV) testing to monitor transformer and cable insulation.
Key parameters tested include:
-
TPC (Total Polar Compounds)
-
Acid Value
-
Moisture
-
Dielectric Breakdown Voltage (BDV)
These tools ensure the timely replacement of oils, preventing equipment failure and enhancing maintenance schedules in various industries, from food production to power utilities.
| Parameter | Test Method | Typical Range | Application |
|---|---|---|---|
| TPC | Colorimetric Strips | 0-32% | Frying Oil |
| Acid Value | Titration | 0-6 mg KOH/g | Lubricants |
| Moisture | Karl Fischer | 0-1000 ppm | Transformer Oil |
| BDV | Dielectric Tester | >30 kV | Insulation Oil |
