Product brand: American YSI $r $n Product model: 55D-12 $r $n Main technical specifications: 55D-12- Dissolved oxygen and temperature measuring instrument $r $n Order number: MM-31836-00 $r $n Portable operation, can also be shoulder hung or waist hung $r $n stainless steel probe, can withstand more severe field conditions; In addition, the weight of the metal makes it easier for the probe to sink into the water. There are three cable lengths available: 3.7 meters, 7.5 meters, and 15 meters
YSI 55type 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
YSI 55 dissolved oxygen and temperature measuring instrument
Integrated dissolved oxygen/temperature probe
Use integrated probes and cables
YSI 55D dissolved oxygen and temperature measuring instrument
The function is the same as the 55 type, using a replaceable "D-type" probe and cable
Different lengths of cables can be replaced at any time according to the needs of different applications
Using MS (specification) type connectors, rain and dust resistant, can be disassembled and maintained in the field
Note: The host does not come with connectors and cables, and requires an additional D-type probe and cable
