How to Calibrate Scientific Instruments: A Step-by-Step Guide

Accurate data is essential for good science, which is why it’s so important to ensure that all of your instruments are calibrated. In this article, we discuss calibration for popular instruments used to monitor water quality and flow, including YSI ProDSS, YSI EXO, YSI Pro Series, and the Lamotte 2020i. Regular calibration is essential to keep these water quality meters working optimally. At Hoskin Scientific, we offer rental equipment and expert calibration services to ensure you achieve accurate results every time. 

 

Your Guide to Understanding Calibration

The term “calibration” refers to the process of adjusting scientific instruments to verify the accuracy of the results. You need to be sure that the measurements are reliable, which is why regular calibration should be part of your routine. Calibration is particularly important when these tools are used in changing environments with water exposure, humidity, and fluctuating temperatures. These conditions can impact the performance of a water quality meter over time, so regular calibration is necessary to extend its lifespan and ensure accuracy. Not only does our team at Hoskin Scientific offer calibration support for your equipment, but you can also follow various industry standards from organizations such as ASTM International. This framework helps to maintain global benchmarks when these instruments are used around the world.

 

Calibrating YSI ProDSS, YSI EXO, or YSI Pro Series

 

Step 1: Preparation

Start by gathering all the necessary tools needed for the calibration. Also, take time to review the calibration instructions for the specific instrument you are using. Make sure that the meter is clean, especially if you are using rented equipment. These instruments are expensive, which is why it’s common to use water quality meter rentals in Canada for your short-term project.

 

Step 2: Calibration Process

The meter needs to be connected to the calibration software. This software works as the interface that guides your calibration to achieve optimal accuracy. Once the software is connected, use a previously established oxygen concentration as a reference point. The meter will adjust the readings to align with the actual oxygen levels. Follow the software’s instructions to make necessary adjustments. The goal is for the meter to match the reference concentration.

 

Step 3: Verifying the Calibration

Finally, confirm the accuracy of this calibration by comparing readings with the reference values that you are using.

 

Tips for Accuracy and Durability

Make sure that you clean and inspect the sensor regularly. Additionally, be proactive about proper storage when the instrument is not in use—especially if you are using a rented water quality meter in Canada.

 

Calibrating a Lamotte 2020i

 

Step 1: Preparation

The most effective solution to prepare your Lamotte 2020i is to set the calibration standards with previously established values. You need a set of measurements that will act as reference points during the calibration. Also, ensure you are using fresh calibration solutions that are stored properly (free of contamination).

 

Step 2: Calibration Process

Review and follow instructions from the manufacturer outlining the progression through various testing standards. For example, you will test the meter with solutions that contain varying turbidity levels. Then, adjust the meter settings so that the readings match the known values. Be deliberate to ensure accuracy at every step.

 

Step 3: Verification

Once the calibration is complete, confirm the accuracy of the Lamotte 2020i by testing it with a standard solution. If you notice any discrepancies in the verification stage, repeat the calibrations as outlined in step 2.

 

Tips for Accuracy and Durability

As with other instruments, regular calibration is essential to ensure accurate measurements. Also, be proactive about proper storage to protect the Lamotte 2020i from physical damage. If you are using a Lamotte 2020i, talk to our experienced team for more specific information about maintenance and storage recommendations.

 

General Tips for Ensuring Accuracy and Durability

Follow these tips to protect all of the instruments you are using:

• Be proactive with regular maintenance and cleaning.
• Prevent damage by using proper storage equipment.
• Recalibrate regularly, especially when using the instrument frequently or in differing environmental conditions.
• Instead of buying, consider renting options such as a sonde for rent in Canada, giving you access to the latest technology in the industry.
