ACS-5000

Based on the highly successful AC9 and ACS, ACS-5000 offers almost an order of magnitude increase in spectral resolution of in-situ absorption and beam attenuation. The 4 nm resolution allows for spectral "fingerprinting" and deconvolution analysis.

Building on the proven technology of the ACS we have designed a 5000 meter rated spectrophotometer. It features a proven flow-through system, compact size, and excellent stability. With 80 (+/-5) wavelength outputs from 400–730 nm, the 4 nm resolution allows for spectral “fingerprinting” and deconvolution analysis. The ac-s employs a 25-cm pathlength for effective measurement of the cleanest natural waters.

The WET Labs Archive Processing program (WAP) provides primary processing of data files created by DH4 data handler and ac-s and ACS-5000 meters. This primary processing consists of extracting time-stamped raw data from the archive files and applying calibration coefficients to the data for all WET Labs instruments and selected instruments from other manufacturers.

What should I use to lubricate bulkhead connectors?

WET Labs recommends keeping the connectors on your meter lubricated using a good quality silicone spray lubricant, such as 3M Silicone Spray or Loctite 8021 spray. These can be purchased at your local hardware store. Avoid silicone grease. It is messy and attracts contaminants.

Do not use WD-40. It will destroy connectors.
