Offline Detection:

Directly sample and test from the sample bottle; use a pressure bottle sampler (with pressure device) for sampling and testing.
Online Inspection:
Can be installed on various hydraulic transmission, lubrication, oil filtering machines, cleaning equipment, and testing stations, enabling online detection of the oil contamination level (cleanliness) of the system.
Performance Features:
Utilizing the principle of photoresist (light blocking) method, it boasts advantages such as fast detection speed, strong anti-interference capability, high accuracy, and good repeatability.
High-resolution power and accuracy of sensors.
Meters and sampling systems for consistent sampling speed and volume control.
4.3-inch color LCD display with touch screen operation.
