Product Details:

HI 9147 Dissolved Oxygen Meter is a water-resistant Dissolved Oxygen meter with manual calibration, automatic temperature compensation (ATC), salinity compensation and direct probe.
The instrument is equipped with an inductive system for battery recharge, with no external contact, to ensure a watertight seal. Dissolved Oxygen is indicated in mg/L (ppm) or in % of saturation.The temperature can be measured in the range from -5 to 50°C. The Dissolved Oxygen readings are automatically compensated for the temperature effects on the oxygen solubility and membrane permeability. Moreover, the salinity compensation feature allows determination of Dissolved Oxygen even in salty waters.
The meter is housed in a rugged water-resistant case for maximum protection in the field as well as in the laboratory.
The D.O. probe is provided with a membrane covering the galvanic sensors and a built-in thermistor for temperature measurement and compensation. The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter. Oxygen that passes through the membrane causes a current flow, from which the oxygen concentration is determined.

Key Features:

• Designed specifically for aquaculture
• Galvanic DO probe
• Backlit LCD
• Automatic Temperature Compensation
• Manual salinity and altitude compensation
• Water-resistant

Product Details:

The HI 98193 Dissolved Oxygen  is a state of art, microprocessor based, dissolved oxygen instrument with many automated and specific application features, designed to provide laboratory results and accuracy under harsh industrial conditions.
All measurements are automatically compensated for temperature. Manual salinity compensation in water allows direct determination of dissolved oxygen in saline waters. With its internal barometer, the instrument is able to automatically compensate for changes in barometric pressure so there is no need for charts, altitude information or external barometric pressure information.
The instrument contains built-in application software for the calculation of Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR).
HI 98193’s calibration has been greatly simplified when compared to other dissolved oxygen instruments. It is provided with a series of new features which add entirely new dimensions to the measurement of DO, by allowing the user to dramatically improve the reliability of the measurement.

• One or two points automatic dissolved oxygen calibration.
• One point manual dissolved oxygen calibration using a value in milligrams per liter or percent saturation entered by the user.
• One or two points user temperature calibration.
• Messages on the graphic LCD for an easy and accurate calibration.
• User-selectable “calibration time out” to remind when a new calibration is necessary

Moreover, the meter offers an extended temperature range from -20 °C to 120 °C (-4 °F to 248 °F). Other features include:

• Log on demand up to 400 samples.
• Auto Hold feature, to freeze first stable reading on the LCD.
• GLP feature, to view last calibration data.
• PC interface.

Product Details:

HI-9142 Dissolved Oxygen Meter is a rugged, waterproof meter that solves the common problems of field use, such as cold, rain, snow and dust, that can damage a meter, rapidly deteriorating its performance and life It is very simple to use: calibration is performed with HI 7040 zero oxygen solution, while 100% calibration is done in air. The polarographic probe (HI 76407/4) is provided with a membrane covering the sensors and a built-in thermistor for temperature measurement and compensation. The thin permeable membrane isolates the sensor elements from the testing solution, but allows oxygen to enter. When a voltage is applied across the sensor, oxygen that has passed through the membrane reacts causing current to flow, allowing the determination of oxygen. The probe included with the meter is supplied with a 4 m (13') cable that allows measurements to be taken even in even hard to reach places. For applications that require longer probe cables, the HI 76407/10 and HI 76407/20 probes with a 10 m (33') or 20 m (67') cable are available
