Product Details
550A-50 -Portable dissolved oxygen meter
The YSI 550A adopts a fully waterproof (IP67 waterproof rating) and impact resistant instrument housing, and features an innovative field replaceable dissolved oxygen electrode module. Using YSI's proven polarographic technique and YSI's high-precision temperature sensitive resistor technique, dissolved oxygen and temperature can be measured simultaneously. The new generation of PE cover film provides faster reaction time and lower stirring dependence.
Fully water tight, compliant with IP67 waterproofLevel
Field replaceable dissolved oxygen electrode module
Faster reaction time, lower stirring dependence
Stainless steel probe, sturdy and durable, easier to sink into water
Install stress relievers at both ends of the cable interface to reduce material fatigue at the connection and effectively extend the cable's lifespan
Built in dissolved oxygen calibration room/probe storage room, convenient to carry and maintain the normal working state of the probe
Available with 3.7, 7.5, 15, and 30 meter cables for selection
The measurement range of dissolved oxygen has been expanded to 50 milligrams per liter
Air saturation or milligram/liter calibration mode
Over 2000 hoursLong battery life
