GENERAL DESCRIPTION

Oxycheck

 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.
Two models are available:
• 

HI 9147-04 

with 

HI 76409/4

 probe (4 m cable)

• 

HI 9147-10 

with 

HI 76409/10

 probe (10 m cable)
