Description
Model: AD330 – AD332
AD330 and AD332 are waterproof portable meters that read TDS and Conductivity in 5 ranges and temperature.
The auto ranging feature of the EC and TDS ranges automatically sets the instrument to scale with the highest resolution. Measurements are compensated for temperature effect automatically (ATC) or manually (MTC). It is also possible to disable the temperature compensation feature to measure the actual conductivity.
The temperature coefficient is user selectable. These instruments also features a measurement stability indicator, GLP capability and a user selectable ID code to uniquely identify the instrument.
Moreover, AD332 includes PC interface and printing function. Connect the meter to an external serial printer with the following printer specifications:
- at least 16 characters / line
- baud rate 9600
- 9 – pin RS232 input
AD330 and AD332 are supplied with:
- User manual
- 1.5V AA alkaline battery (4pcs)
