Product Details

YSI 55 dissolved oxygen and temperature measuring instrument:

·Handheld operation, can also be hung on the shoulder or waist

·Stainless steel probe, capable of withstanding more severe field conditions; Additionally, the weight of the metal makes it easier for the probe to sink into the water

·Available in three cable lengths of 3.7 meters, 7.5 meters, and 15 meters for selection

·Full button calibration and operation, all operations are controlled by a microprocessor

·Simultaneously display dissolved oxygen and temperature readings, with the option to display air saturation or milligrams per liter concentration

·Can directly input salinity to compensate for the deviation of dissolved oxygen in different water bodies

·Height can be directly input to compensate for the deviation of dissolved oxygen caused by air pressure at different heights

·The cable joint is equipped with a stress reliever to reduce material fatigue at the connection point and effectively extend the service life of the cable

·Built in calibration room for easy air calibration; The calibration room can also serve as a probe storage room at the same time

·Extra large LCD display screen with background lighting function, allowing clear reading even in dim environments

·Full battery operation, with a working life of up to 100 hours (alkaline battery); There is also a low battery display
