Dissolved Oxygen Setup - Hanna Instruments Edge Instruction Manual

Steps To Optimize
1. Determine if Concentration or % Saturated measurements will be made.
2. Prepare the D.O. probe for measurement.
3. Connect the probe to the meter and configure the SETUP parameters.
4. Calibrate the D.O. sensor.
5. Take measurements using the DO sensor.
Measurements Available
Concentration measurements in water, and % oxygen saturated
measurements are available using edge™ together with HI 764080 DO probe.
Algorithms used for concentration measurements (units of ppm or mg/L) are
based upon the oxygen solubility in air-saturated fresh water. Compensation
for salinity and altitude are made by configuring SETUP parameters. Percent
saturation measurements are based upon the partial pressure of oxygen and
are suitable for measurement in samples other than air saturated fresh water.
It is advised to check material compatibility of the probe with the sample.
DO Probe Preparation
CAUTION: Use care during servicing and use. The
HI 764080 contains a glass insulator. Do not drop or handle
carelessly.
Probes from Hanna Instruments are shipped dry.
1. Carefully remove the cardboard shipping tube used
to protect the probe during shipping. Save should the
probe be stored dry again.
2. Open membrane package and remove one O-ring and
one membrane cap.
3. Position o-ring in cap as indicated.
4. Rinse the membrane cap with a small amount of HI
7041 electrolyte and discard. Refill membrane cap 3/4 full
with electrolyte solution, ensure to cover the o-ring.
5. Holding the membrane cap by the top, tap the
side walls of the membrane cap to dislodge gas bubbles
and force them to rise to the surface. Do not tap on the
membrane directly as it may damage it.
6. With the cathode facing down, slowly screw the cap
