The YSI 6920 is an economical logging system for long-term, in situ monitoring and profiling. It will log all parameters at programmable intervals and store 150,000 readings. At 15-minute intervals, it will log data for about 30 days.
A cost-effective logging unit rated at 200 feet, the YSI 6920 can monitor up to 14 parameters simultaneously, including oxygen with the YSI Rapid PulseTM stirring-independent sensor and turbidity sensor not affected by variations in ambient light that has a self-cleaning feature. A self-cleaning chlorophyll sensor may be installed instead of the turbidity sensor.
The 6920 V2 is a cost-effective sampling system for both spot-sampling and long-term unattended monitoring, with up to a 14-parameter reporting capability.
Available optical sensors:
The YSI 600XLM provides economical logging in a small package for both surface and groundwater. It measures a range of fundamental parameters, including oxygen, temperature, conductivity, pH, ORP, non-vented level and salinity. The log will capture parameters at varied intervals and can store 150,000 readings.
Rugged and reliable, the YSI 556 MPS water quality analyzer (Multi probe system) combines the versatility of an easy-to-use, easy-to-read handheld unit with all the functionality of a multi-parameter system. Featuring an IP-67, impact resistant case, the YSI 556 MPS simultaneously measures dissovled oxygen, pH, conductivity, salinity, temperature and ORP.
This monitor is designed for water quality applications and mainly used in the environmental industry. While this unit comes with a 4m cable, it also rents with the option of a 10m or 20m cable and Flow Cell.
Carrying Case - the instrument comes standard with a soft-sided carrying case with enough space for the YSI 556 MPS, a 4m cable (10 meter cable optional), flow cell and calibrating supplies. A handstrap can be connected on either the right or left side of the instrument.
Looking for a rugged, field worthy instrument for measuring dissovled oxygen? The new YSI 550A Dissolved Oxygen instument features a waterproof (IP-67), impact-resistant case and innovative field-replaceable dissolved oxygen electrode modules. Measure dissovled Oxygen and temperature simultaneously using YSI's proveb polarographic technology for oxygen and YSI temperature precision thermistors, the planetwide standard for accuracy. The new PE membranes provide faster response times with less stirring dependence - saving time with every reading!
The YSI Professional Plus handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP and temperature. Also a very powerful lab instrument for BODs, pH and ORP.
Additional probes are available on request which measure the following parameters: pH/ORP combination, ammonium (ammonia), nitrate, chloride.
The Pro Plus instrument meets the demands of true field work. The instrument is rated to IP-67 standards even without the battery cover on. Other tough features include a Mil-spec connectors and a rubber overmolded case. In-house testing procedures also include 1-meter drop tests from all angles to ensure expected field-durability.
The instrument provides numerous benefits from the following features; 5,000 data-set memory, password protection, backlit display and keypad, graphic display with detailed Help functionality, re-cal prompts, user defined fields, detailed GLP, auto stable, Hold All Readings function, Data Manager software for the desktop, USB connection, auto-buffer recognition, and flexible folders and site lists for logging data.
Field-proven, the YSI 55 DO Instrument measures dissolved oxygen in mg/L or percent saturation. Offering push-button calibration with a built-in calibration chamber, direct salinity, and altitude compensation, the YSI 55 provides simultaneous readings of oxygen and temperature. Dissolved oxygen readings are automatically compensated for temperature. Also available is the YSI 55D with a detachable cable.
A cost-effective sampling system with 14-parameter reporting capability, the YSI 6820 is ideal for profiling and spot-checking in lakes, rivers, wetlands, wells, estuaries, and coastal waters. The YSI 6820 measures nine parameters simultaneously, including dissolved oxygen, using the YSI Rapid PulseTM stirring-independent sensor and turbidity or chlorophyll, using a sensor with a self-cleaning feature for long deployments, or a standard sensor for simple sampling. Even though the YSI 6820 is small in size it is designed to sink without additional weight.
RS-232 and SDI-12 are standard; the YSI 6820 easily interfaces with a YSI 6200 Data Acquisition System, many other data collection platforms for long-term deployment, or a YSI 650 Multiparameter Display System for sampling.
All YSI 6-Series sondes can be used with YSI EcoWatch for Windows software. EcoWatch is communication and data processing software that is fast and easy-to-use. See the whole picture with a single program, obtain statistics easily, merge data files, and run large studies.
The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO1 sonde for estuarine, surface water, or ground water applications.
