Precision + Range
Every particle.
Every pressure.
A wear-resistant ceramic piston pump holds a constant flow across pressureless, low-pressure, and high-pressure sampling up to 420 bar (6000 psi). The PAMAS HCB-LD-50/50 volumetric sensor is calibrated to 4–70 µm(c) per ISO 11171 as standard, with an optional 2–100 µm calibration per ISO 4402, at a maximum particle concentration of 24,000 P/mL.
Built for field and bench.
Standard sampling covers fluids up to 200 cSt, extending to 350 cSt under pressurized sampling and 1,000 cSt on the lube oil system.
