Oximeter HANNA HI 9142 (portable)
Oximeter HANNA HI 9142 (portable) Designed for daily measurements during the biological treatment of drinking water. The HI 9142 is an easy-to-use dissolved oxygen (DO) meter with a polarographic sensor. During field work, instruments may be exposed to inclement weather. Cold, rain, dust and moisture can cause condensation to form on parts of the housing. The waterproof housing of the HI 9142 successfully withstands many of the difficulties of working in the field. Zero point calibration is performed using zero dissolved oxygen solution HI 7040 and 100% point calibration is performed in air. The polarographic sensor (HI 76407/4) works with an accuracy of 0.3 ppm and comes with a 4 m cable, allowing measurements even in hard-to-reach places.
