Do I have to use bluelab calibration solution?
Bluelab pH 7.0 Calibration Solution – 500 ml is essential for use with all Bluelab pH products. All Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab products last longer and maintain accuracy.
How do you calibrate the pH on a bluelab pen?
- Turn the pH pen on.
- Calibrate to pH 7 by placing probe tip in fresh pH 7 solution. Wait for reading to stabilise to between pH 6.6 – pH 7.5. Long press the Cal button until CAL is displayed. Release the button. …
- Repeat with pH 4 solution.
- A checkmark will confirm successful calibration.

Can you reuse bluelab calibration solution?
To prevent cross contamination, pour the necessary amount of buffer into a small container and calibrate from here. Discard when finished — do NOT reuse.
How do I know if my pH meter is working?
The only reliable way to determine whether a pH meter is accurate or not is to test it in standard solutions. Just like the only way you can tell if a scale is accurate is to test the standard weights.
Can you reuse calibration fluid?
You never want to re-use buffers for calibration. Once buffers are used for calibration, they are assumed contaminated and should not be used again. Reusing buffers can lead to slow responding pH probe performance or the inability to calibrate at all.
How often should I calibrate my Bluelab pH Pen?
Calibrating your pH pen or probe will ensure accurate readings. To get the best from your pH product, we recommend calibrating once a month.
How often should I calibrate my pH tester?
All pH meters require calibration and should be calibrated anywhere from before every use to at least once a month. The calibration could be 2-point / 3-point and the frequency depends on usage and applications, but at least once a month is strongly recommended for precise results.
How do I use my Bluelab pH Pen?
- Turn the pH pen on. Press the power button. …
- Measure pH. Remove the storage cap, place probe in solution and wait for the reading to stabilise.
- To hold the reading. To hold the reading on the display, short press the power button.
Do you need to calibrate pH pen?
When to calibrate your pH pen
pH calibration is required before first use to ensure that the first reading is accurate. Calibration is also required when: The check mark/tick has disappeared from the LCD screen (30 days after last calibration)
Can you calibrate a pH meter with tap water?
** Before you begin, please ensure you have a container of water to rinse the probe between the 2 buffer solutions during the calibration. If you have Deionized water, Distilled water or RO water (Reverse Osmosis) – any of these are preferred to tap water, however you may use tap water if necessary.
How long will a Bluelab pH Pen last?
How long will my Bluelab pH Pen last? Bluelab’s pH products are charged with reference material which expends over time and use. The average life span of a pH pen is approximately 18 months.

Can you store calibration solution?
pH buffer solutions should always be stored in a cool dry place and should be discarded responsibly if any remains after the expiry date, which is printed on the bottle. When calibrating a pH controller, it is best to calibrate pH7 first and then to calibrate pH4 or pH10.
How long does it take a pH probe to dry out?
The electrode can be soaked in a 4.01 or 7.00 pH Buffer solution, a reference fill solution or regular tap water. The length of time required varies in relationship with the amount of time the electrode was left dry. Typically, from 30 minutes for short dry periods, to 24 hours for more severe instances.
How long do buffer solutions last?
When opening a bottle of buffer solution, it can be helpful to write the date opened on the bottle. 4. After opening, a bottle of 4 or 7 buffer solution should last approximately 3 to 6 months and a bottle of pH 10 buffer should last approximately one month. 5.
How do you prepare a buffer solution for pH meter calibration?
- Potassium Tetraoxalate (0.05M) – Dissolve 12.61 g of KH3(C2O4)2. …
- Potassium Biphthalate (0.05M) – Dissolve 10.12 g of KHC8H4O4 previously dried at 110 C for 1 hour, in water to make 1000 ml.
When should I change my pH electrode?
Current pH electrodes have a lifespan of about one year or up to 18 months at the most (with less frequent use). If you properly care for your electrodes, you’ll still need to replace them roughly annually.
What is an acceptable slope for pH meter calibration?
The theoretical slope value is -58 (+/- 3) mV per pH unit, so typically any value between -55 and -61 mv is acceptable for calibration.
How often should you calibrate Hanna pH meter?
A couple of tips when calibrating the Hanna pH Checker Plus is always to use new calibration solutions, and to rinse the probe end in RODI or distilled water between sachets. We like to calibrate our probes once every one to three months depending on how often we are using the particular probe.
Why do we use buffer solution to calibrate pH meter?
Buffer solutions are used to calibrate pH meters because they resist changes in pH. When you use a pH meter to measure pH, you want to be sure that if the meter says pH = 7.00, the pH really is 7.00. So you use solutions of known pH and adjust the meter to display those values.
What is calibration solution?
pH calibration solutions, also called pH buffers, are an essential tool when measuring pH with a pH meter and electrode.
