John Morris Scientific has introduced the YSI 556 MPS, a rugged handheld multi-probe system ideal for field use in groundwater and surface water.
Featuring a waterproof IP67, impact-resistant case, the 556 MPS can simultaneously measure dissolved oxygen, pH, conductivity, temperature, and ORP.
The 556 MPS will log more than 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.
It is supplied with a 4, 10 or 20m cable, and protective case.
It features field-replaceable sensors, and simple 'cap-type' DO membranes.
The YSI 556 will easily fit down a standard 2in well for in-situ monitoring.
An optional flow-through cell, screws onto the 556 for use in pumped or purged applications.
The 556 with flow cell, is ideal for 'low flow purging' applications and methodology.
