About this file

This is a specifications document for a portable particle counter with integrated bottle sampler required for federal contract procurement. The particle counter must be new condition and powered by a lithium-ion rechargeable battery with minimum 8-hour runtime. The device must employ high-precision LED light extinction automatic optical particle counter technology capable of sizing particles at >4, >6, >14, >21, >25, >38, and >70 microns with accuracy of ±1/2 code for 4, 6, and 14 microns and ±1 code for 21, 25, 38, and 70 microns. The counter must be individually calibrated with ISO Medium Test Dust per ISO 11171 and support analysis ranges including AS4059 REV G, ISO 4406, NAS 1638, AS4059/ISO 11218 REV E, GBT14039, GOST 17216, and ISO 11218. Fluid compatibility must include SKYDROL PHOSPHATE ESTER 500B, SKYDROL PHOSPHATE ESTER LD-4, MIL-H-83282, MIL-H-87257, and MIL-H-5606, with viscosity capability up to 400cSt and fluid temperature range of 41–176°F. Operating parameters include ambient temperature range of 14–176°F, pressure rating of 24–6000 psi with on-screen inlet pressure display, programmable test volumes with 100 ml preset, minimum 3500-test data storage capacity, and IP 66 environmental protection when lidded. Maximum weight and dimensions are 22 lbs and 18.5" x 14" x 6.7" respectively. The device must include an onboard printer.

The integrated bottle sampler must be compatible with the particle counter and support the same fluid types. It must have capacity for one 550 ml bottle and one 110 ml bottle with chamber pressure range of 8.85–11.75 psi minimum and 36.3–65.3 psi maximum, including a visual pressure indicator. Outlet pressure must range from 14.7–65.3 psi. Environmental protection rating is IP 50 with maximum weight of 20 lbs and dimensions of 10.5" x 13.5" x 14". Required features include vacuum for fluid de-aeration and a full accessories kit. Delivery is FOB Edwards, California with estimated time of arrival no later than May 2026.
