HANNA HI9142 dissolved oxygen DO Tester Picture

Introduction

As the demand for instant on-site analysis results continues to increase, this creates the need for innovative, rugged, portable and waterproof instrumentation. Field work can expose instruments to adverse weather conditions. Cold, rain, snow, dust, and humidity can cause condensation to enter the housing. Once the housing is damaged, the performance and service life of the instrument will be reduced. The HI9142's rugged, waterproof housing solves many problems of field use. Calibrated using HI7040 zero oxygen solution and 100% calibrated in air. The polarographic probe (HI76407/4) is accurate to 0.3 ppm and comes with a 4 meter (13') cable, allowing measurements even in hard-to-reach places.

H19142 portable Dissolved Oxygen Meter is suitable for the measurement of dissolved oxygen in different water quality and wastewater in various industries. Equipped with a high-performance polarographic sensor dissolved oxygen electrode, oxygen generates current through a specific dissolved oxygen film to ensure measurement stability and accuracy; the dissolved oxygen measurement mode is mg/L (ppm) O2, and this Dissolved Oxygen Meter can be used in the air Calibrate automatically or select 1 or 2 point calibration (0 or 100%).

Features

  • Waterproof design, large screen background light LCD, operation wizard display.

  • The power display icon reminds you to replace the battery in time, and the measurement is accurate and reliable.

  • Automatic compensation for altitude, salinity and temperature, automatic calibration in air.

  • New polarographic dissolved oxygen electrode, suitable for on-site measurement.

  • Measurement results are expressed in ppm (mg/L).

FAQ
QI want to measure the dissolved oxygen in a fish pond, which instrument is suitable?
A HANNA HI9142 dissolved oxygen meter is recommended. It is waterproof and dustproof, suitable for outdoor fish pond environment, with a 4-meter long wire electrode, which can be extended to the depths of the pond for measurement. And automatic temperature compensation, the dissolved oxygen value when measuring the water temperature of the fish pond is more accurate.
QSewage treatment plant daily inspection dissolved oxygen, what instrument to choose?
A HANNA HI9142 is suitable. It is sturdy and waterproof, and can handle the humid environment of the factory area. Polarographic electrode accuracy is 0.3ppm, which meets the requirements of sewage monitoring. The large screen is backlit, which is convenient for reading during inspection, and can automatically calibrate the air, saving time and effort.
QNeed to monitor the river dissolved oxygen for a long time, which function should be selected?
A It is recommended to choose HI9142 with a 10m or 20m long wire electrode configuration. The long cable is suitable for monitoring the center of the river from the shore, and the instrument automatically compensates for water temperature, salinity and altitude to ensure the accuracy of long-term measurement in the field. The battery level display function can also remind you to replace the battery in time.
QI want to measure dissolved oxygen in a wastewater treatment plant. Is there a portable and durable instrument recommended?
A Recommended HANNA HI9142 dissolved oxygen meter, it adopts waterproof design, suitable for outdoor harsh environment use, with 4 meters long cable polarographic electrode, can easily extend into the tank body measurement, automatic temperature compensation to ensure accurate data, suitable for sewage treatment site monitoring.
QIt is necessary to monitor the dissolved oxygen in the river for a long time. Which function should be selected?
A It is recommended to choose HI9142 with a 10-meter or 20-meter long cable model. The ultra-long cable is suitable for monitoring deep water areas from the shore; the instrument has automatic temperature compensation and air Adjustment to reduce the trouble of frequent calibrating, and the battery power display can also remind timely replacement.
