American YSI ProSOLO portable fluorescence dissolved oxygen meter

The American YSI ProSolo portable fluorescence dissolved oxygen meter uses fluorescence lifetime detection technology that does not consume oxygen. It can provide stable, highly repeatable and sensitive dissolved oxygen detection data and reduce sensor drift.
It can be used in routine and emergency measurements of water environment, dissolved oxygen measurement in sewage treatment, teaching and research in universities and scientific research institutions, water quality measurement in aquariums, aquaculture, ecological environment surveys, and dissolved oxygen measurement in other fields.
Product features of the American YSI ProSOLO portable fluorescence dissolved oxygen meter:
The measurement range (0-500%) is wider than other brands of optical dissolved oxygen sensors
Smart digital sensor technology stores calibration data in the sensor, allowing the probe to operate normally even when installed on any uncalibrated ProSolo host
Suitable for 300ml BOD bottles
Users can change the sensor by themselves in the field
It is waterproof. The battery compartment and the instrument circuit compartment are independently separated and sealed. Even if water enters the battery compartment, it will not affect or damage the instrument circuit.
Anti-slip cast shell covered with rubber, easy to grip and long service life
Store 2000 sets of data (including sensor data, date, time, site and user-defined information)
Connect the ProPlus host and computer with the standard USB cable. Not only can it power the host, but you can also use the easy-to-operate Data Manager software to set up the host, manage analysis data, and view graphical and tabular data.
Two measurement modes: automatic/manual sampling mode/continuous real-time measurement mode
Glow-in-the-dark keyboard and backlit display facilitate operation in dim environments
User-selectable cable length, up to 100 meters; cable management kit helps organize cables up to 4 meters or more
MS military connector, quick plug and unplug, waterproof, stable connection
The cable portion of the connector can withstand 300,000 bends
Built-in barometer

Product advantages of the American YSI ProSOLO portable fluorescence dissolved oxygen meter:
Not flow rate limited, no flow rate or agitation dependence
No warm-up time required
Low drift and long-term stability, eliminating the need for frequent calibration
Not affected by hydrogen sulfide or other gases
Low maintenance: no need to clean electrodes or change solutions, only need to replace sensitive components once a year
