Dissolved Oxygen Meter, Waterproof, with Polarographic Probe Kit, Hanna Instruments, HI9142

Features:

 

• Automatic Temperature Compensation
• Affordable and efficient
• DO probe and carrying case included

 

The ever increasing demand for instant results from on-site analysis results has created a need for innovative and rugged portable, waterproof meters.

Field work can subject instrumentation to the inclemency of weather. Cold, rain, snow, dust and humidity can cause condensation to breech the housing, which eventually compromises the meter and rapidly diminishes its performance and life. HI 9142 is a rugged, waterproof meter that solves many of the common problems of field use.

It is very simple to use: calibration is performed with HI 7040 zero oxygen solution, while 100% calibration is done in air.

There is no need to use chemical solutions or go through time consuming calibration procedures. The polarographic probe (HI 76407/4) is accurate to 0.3 ppm in minutes and is supplied with a 4m (13') cable that allows measurements to be taken even in hard to reach places.

For applications that require longer probe cables, the HI 76407/10 and HI 76407/20 probes with a 10m (33') or 20m (67') cable are available.
