Jenway 9500 Bench DO

2

 Meter

E23-31 

   

The 9500 is a DO

2

 research meter designed for use in a number of applications including fish 

farming/breeding, all forms of aquaculture, environmental analysis, pollution control and 
effluent management. The 9500 includes powerful data logging capabilities with the ability 
to store 250 DO2 readings either manually, at timed intervals or on alarmed events. The 
9500 also includes full support for the BODs day test protocol and has the ability to store up 
to 25 BOD data sets, each with up to 10 samples.

Jenway 3540 pH/Conductivity Meter

E23-31 

   

The 3540 is ideal for use in all laboratories where pH and conductivity analyses are required. 
The setup menu gives quick and easy access to the whole range of instrument, pH and 
conductivity measurement options. Calibration of both channels is automatic, with the option 
to select 1, 2 or 3 calibration points. The pH channel can also display mV values if required.

 



Simultaneous display of pH and conductivity

 



2 independent channels to prevent interference between probes

 



Additional modes for resistivity, salinity, TDS and mV

 



Data logger with auto save/print options

 



 Storage of up to 500 readings (250 for each mode)
