FAQs
Q: Can this portable oil particle counter work under high temperature and high pressure conditions?
A: Yes. This portable liquid particle counter adapts to harsh working sites for oil contamination testing.
Q: What extra data can this particle tester get results?
A: It has built-in moisture and temperature sensors. Users get oil-water content and oil temperature together with particle count testing.
Q: Does the hydraulic oil particle counter support on-site printout for test reports?
A: Yes. The oil particle counter can print test results directly on site for easy record-keeping.
Q: Do I need extra tools to take oil samples for detection?
A: No extra complex tools are required. The built-in metering pump helps finish sampling quickly for field particle measuring.
Q: How should I store this portable particle counter after field testing?
A: Clean the inner flow path first, then put the unit in the protective case. Keep it in dry places to protect the optical particle counter sensor.
