John Morris Scientific has introduced YSI 556 MPS, a rugged handheld multi-probe system which is ideal for field use in both groundwater and surface water.
Featuring a waterproof IP-67, impact-resistant case, the YSI 556 MPS can simultaneously measure dissolved oxygen, pH, conductivity, temperature, and ORP.
The YSI 556 MPS will log over 49,000 data sets, each stamped with time, date and site name. Up to 99 site names can be stored.
All stored data can be downloaded to a computer with YSI's free Ecowatch software. YSI 556 MPS is supplied with a 4, 10 or 20m cable, and protective case. YSI 556 MPS features field replaceable sensors, and simple cap-type DO membranes.
The YSI 556 MPS will easily fit down a standard 2 inch well for in-situ monitoring. An optional flow through cell, screws onto the YSI 556 MPS for use in pumped or purged applications. The YSI 556 MPS with flow cell, is ideal for low flow purging applications and methodology.
