How to Properly Use the Milwaukee SM600 dissolved oxygen meter: A Step-by-Step Guide
The Milwaukee SM600 dissolved oxygen meter is a valuable tool for measuring the amount of oxygen dissolved in water. Proper usage of this device is essential to obtaining accurate and reliable results. In this article, we will provide a step-by-step guide on how to properly use the Milwaukee SM600 dissolved oxygen meter.
First and foremost, it is important to familiarize yourself with the components of the Milwaukee SM600 dissolved oxygen meter. The meter consists of a main unit, a probe, and a calibration solution. Before using the meter, ensure that the probe is securely connected to the main unit and that the calibration solution is on hand.
To begin using the Milwaukee SM600 dissolved oxygen meter, turn on the main unit by pressing the power button. The display screen will light up, indicating that the meter is ready for use. Next, immerse the probe into the water sample that you wish to measure. Make sure that the probe is fully submerged and that there are no air bubbles trapped around the sensor.
Once the probe is properly immersed in the water sample, wait for the meter to stabilize and display a reading. The dissolved oxygen level will be shown on the screen in units of milligrams per liter (mg/L) or percentage saturation. Take note of the reading and record it for future reference.
To ensure the accuracy of the measurements, it is important to calibrate the Milwaukee SM600 dissolved oxygen meter regularly. To calibrate the meter, first prepare the calibration solution according to the instructions provided in the manual. Immerse the probe into the calibration solution and adjust the meter to match the known value of the solution.

After calibrating the meter, rinse the probe with clean water to remove any residue from the calibration solution. This will prevent contamination and ensure accurate readings in future measurements. It is also recommended to store the probe in a protective case when not in use to prevent damage.
In addition to calibration, it is important to properly maintain the Milwaukee SM600 dissolved oxygen meter to prolong its lifespan and ensure accurate measurements. Clean the probe regularly with a soft cloth or brush to remove any debris or buildup that may affect the readings. Store the meter in a cool, dry place away from direct sunlight to prevent damage to the components.
In conclusion, the Milwaukee SM600 dissolved oxygen meter is a valuable tool for measuring dissolved oxygen levels in water. By following the step-by-step guide outlined in this article, you can ensure accurate and reliable measurements with this device. Proper usage, calibration, and maintenance are essential to obtaining accurate results and prolonging the lifespan of the meter.
