Filtration & Monitoring Solutions for hydraulic oil and lubricants

LPA2 – Laser Particle Analyser

The LPA2 is a highly precise, lightweight & fully portable twin laser particle analyser and particle counter suitable for on-site and laboratory applications. It can automatically measure and display particulate contamination, moisture and temperature levels in various hydraulic fluids.

The LPA2 gives accurate results of the amounts and sizes of contaminants instant results. LPA2 is calibrated with ISO Medium Test Dust (MTD) based on ISO 11171:1999 calibration standard. The new MTD has a certified distribution standard verified by NIST (National Institute of Standard and Technology), USA. The LPA2 is designed to meet the new ISO 4406 cleanliness classification code which is a 3-part code, 4µm(c), 6µm(c) and 14µm(c). The LPA2 also provides results in the NAS 1638 and the SAE4059 code.
