Overview

Using the Star A329 Multiparameter water quality meter, you can quickly and easily get the information you need from the large, backlit graphic LCD display. The informative display can show all three parameters with temperature at once or each parameter with temperature individually.

The A329 water quality meter features a range of advanced features including a non-volatile memory, a multi language interface, stability and averaging options and AUTO-READ with ready indicator to lock in the stable reading.

It's easy to get accurate DO results with automatic temperature, automatic/manual barometric pressure and automatic salinity compensation when used with simultaneously with conductivity. The meter accepts and automatically recognizes Orion polarographic and optical/ luminescence-based probes so there is no issue with compatibility.

The A329 water quality meters allow up to 5 point ISE calibration with advanced features such as timed end point, linear point-to-point, non-linear selectable auto-blank and low-concentration range stability.

Selectable reading reference temperatures of 5, 10, 15, 20 or 25 °C with linear, non-linear, nLFu or EP curve options provide advanced accuracy in conductivity readings.

The user can easily transfer data and keep meter software up to date with the USB and RS232 ports and data analysis software.

The meter is powered by four AA batteries which provide 800 hours of operation. A universal power adapter is also available to use AC power.
