Dissolved Oxygen Meters - Hanna Instruments

Hanna uses the latest in electronic and sensor technology in its line of Dissolved Oxygen Meters to bring users high performance and reliability. Being one of the few worldwide manufacturers of D.O. meters, Hanna took on the task of providing the industry with a diverse range of products to meet all application needs.     gzm

Where compensation is not automatic, reference tables for corrections are included in the user manual.

Included with the instruments: Probe on 4m cable, 2 spare membranes, electrolyte solution, battery, instruction manual, rugged carry case.

HI9142 Waterproof, Dissolved Oxygen Meter Water Resistant Casing The rugged construction is water resistant, IP67, making it indispensable in the biological water treatment industry. One Point Calibration With the probe in saturated air, the meter can be calibrated without the need for chemical solutions. ATC Circuitry The meter's built-in Automatic Temperature Compensation circuitry will adjust all readings to provide the utmost accuracy. Low Battery Indicator The low battery indicator gives the user advanced notice to avoid taking an erroneous reading due to low power.   Data on HI9142: click here

The ever increasing demand for instant results for on-site analyses has created a constant need for waterproof portable meters.

The cold, rain, snow and dust associated with use in the field, may damage a meter, rapidly deteriorating its performance and life.

HI9142 is a rugged, water resistant meter that solves the common problems of field use, IP67 rated.
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 processes.

The polarographic probe (HI 76407/4) will take measurements accurate to 0.2 ppm O2/liter in less than 1 minute and is equipped with a 13' (4m) cable that allows measurements to be taken in even hard to reach places.

For applications that require a longer probe cable, the HI 76407/10 probe with a 32.8 foot (10 meter) cable is available.

The conic shape of the probe allows it to be used in all BOD5 measurements making it a truly versatile instrument.

HI 9142 is supplied complete with an HI 76407/4 D.O. probe, 2 spare membranes, HI 7041S electrolyte solution, 4 x 1.5V AA batteries and instruction manual in a rugged carrying case.

HI 9143 • HI 9145 Extended Range in a Waterproof Casing Battery or VDC power When used for extended periods of time, there is no need to interrupt important tests, simply plug into a 12 VDC battery charger. Automatic Calibration Simply expose the probe to saturated air and press the CAL button. No need for messy solutions or tedious calibration processes. Extended Range The new and improved HI 9143 and HI 9145 come with an extended range of up to 300% and 45 mg/L of DO.   Data on HI9143 and HI9145: click here

Cold, rain, snow, dust and humidity associated with use in the field can cause condensation which may damage a meter, rapidly deteriorating its performance and life.

HI 9143 and HI 9145 are designed for outdoor applications, especially waste water treatment and fish farming. Simple on-site calibration requires no chemical solutions. Just expose the probe to air and press the CAL button. In a few minutes the meter is calibrated and ready to use. Auto-calibration eliminates the need to use a screwdriver or other devices to adjust the reading.

The basic version, HI 9145, provides readings of O2 (% or mg/l) and temperature.
HI 9143 also supplies the user with compensation of salinity and altitude factors in addition to the features of HI 9145.

Both meters compensate for temperature effect.
HI 9143 & HI 9145 are supplied complete with HI 76407/4 D.O. probe
with 4 m (13') cable, 2 spare membranes, HI 7041S electrolyte solution,
4 x 1.5V AA batteries and instruction manual in a rugged carrying case.
