Introduction 

The YK801B comes already assembled. The only construction required is to connect the probe assembly to the 
reader unit.  

General Description 

The model 801B Water Quality Analyser Reading Unit is a robust Optical DO field instrument which can be used 
for real time water quality measurements or for remote operation using a built in data logger.   

The instrument consists of a Optical DO and temperature sensor probes and a reader unit which can store, log 
and display data. The probe and reader unit have been designed to be compact, durable and easy to use. Data is 
transferred to the reader unit using Bluetooth. The reader unit controls the operation of the instrument, 
provides easy access to the data, control, memory and calibration functions. The reader unit contains a real time 
clock and all stored data includes the date and time of measurement. Both stored data and calibration 
information can be easily down loaded to a computer using the data transfer program, YK Quick Terminal.  

The battery charger is supplied with this reader unit.
