How do you calibrate a Hach probe?

Table of Contents

Rinse the probe with deionized water. Dry the probe with a lint-free cloth.
Add a small amount of water (approximately 1 cm) to the bottom of narrow- neck bottle, such as a BOD bottle. Insert a stopper and shake the bottle vigorously for several minutes.
Push Calibrate. Push Read.

How do you calibrate a probe?

Correct calibration protocols

Place the probe in a BOD bottle containing about 3 cm of water.
Shake BOD bottle prior to inserting probe to assure saturation.
The probe may need to sit in the bottle for 30-35 minutes in order to match the temperature of the air.

How do I calibrate my hq30d?

1) Connect the probe to the meter. *(Never touch the sensor cap with hands).
3) Shake vigorously for 30 seconds.
5) Remove probe safety guard *(do not touch sensor cap).
6) Push the CALIBRATE key, and press the green button to activate calibration.
7) Select READ.
9) Select Store to accept calibration.

Do probes Hach?

The Hach LDO probe requires no calibration and can be used right out of the box. Using this DO probe to monitor dissolved oxygen levels in your water applications saves time and money through minimum maintenance (no electrolyte solution) and overall reduction in aeration blower energy usage.

How does the Hach DO probe work?

Principle of operation: The HACH LDO sensor is coated with a luminescent material. Blue light from an LED is transmitted to the sensor surface. The blue light excites the luminescent material. As the material relaxes, it emits red light.

How do you calibrate oxygen?

-For the first point, push and hold the calibrate button on the sensor using a paper clip or LabQuest stylus. -Enter a value of 0 for this reading. -Release the button and take a second reading in air. -Enter a value of 20.9% oxygen or a corrected value from the table in the sensor booklet.

What temperature should probes be calibrated?

HOT CALIBRATION METHOD Place the probe into the container. Check that the temperature is between 99°C and 101°C (210°F to 214°F). If the temperature is not correct, adjust your thermometer to the correct temperature while it is still in the water.

How does an orbisphere work?

The measuring LED emits a pulse of blue light which irradiates the back of the oxygen sensitive spot. The coating material reacts with luminescence and emits a pulse of red light where the intensity and time delay are measured.

How do you measure dissolved oxygen?

Dissolved oxygen levels can be measured by a basic chemical analysis method (titration method), an electrochemical analysis method (diaphragm electrode method), and a photochemical analysis method (fluorescence method).

How does luminescent dissolved oxygen work?

See How it Works The measuring LED emits a pulse of blue light which irradiates the back of the oxygen sensitive spot. The coating material reacts with luminescence and emits a pulse of red light where the intensity and time delay are measured.

How do Hach dissolved oxygen probes work?

Let us first look at the probe. The Hach dissolved oxygen probes are equipped with a measuring LED that emits a pulse of blue light and a photodiode as a light detector. The probes are also equipped with a sensitive luminescent coated spot that is exposed to the sample.
