Description
Meytec RX 475 mV redox calibration solution bottle 60 ml
The Meytec RX 475 mV redox calibration solution bottle 60 ml is a reference liquid for calibrating and checking orp probes used in swimming pools, spas and water treatment systems. It provides a stable potential around 475 mV, allowing you to adjust electronic sensors so redox readings remain accurate and repeatable over time.
Application and measurement range
Orp probes gradually drift as the electrode surface ages and is exposed to disinfectants, salts and temperature changes. Calibrating or verifying with Meytec RX 475 mV redox calibration solution helps correct this drift in the typical working zone for disinfected pool water, where redox control is often used to modulate chlorine dosing.
A well defined 475 mV reference makes it easier to distinguish between real changes in water quality and simple sensor ageing. Regular checks against this standard improve confidence in the readings used to control disinfection.
Compact 60 ml bottle for test kits
The Meytec RX 475 mV redox calibration solution bottle 60 ml is supplied in a compact screw cap bottle that fits easily into portable photometer or meter kits. The smaller volume is ideal for residential pools, small commercial installations and mobile technicians who calibrate a limited number of instruments.
- 60 ml of ready to use RX 475 mV calibration solution.
- Space saving bottle for service cases and on site testing.
- Practical choice when you want fresh solution without large stocks.
For best preservation of the reference value, only the amount needed for one calibration should be poured into a clean container while the main bottle stays closed.
Calibration and verification of orp probes
The Meytec RX 475 mV redox calibration solution bottle 60 ml is compatible with most orp and redox meters that accept external calibration standards. It can be used for full calibration, where the instrument is adjusted to the reference value, or as a quick verification standard for routine maintenance.
- Mid range reference point for orp and redox meters in pool water.
- Suitable for handheld testers, fixed controllers and multi parameter meters.
- Helps confirm that probes controlling chlorine dosing remain accurate.
Always follow the calibration procedure described in the instrument manual, including any requirements for immersion depth, stabilisation time and temperature compensation around the 475 mV reference.
Example verification procedure
A simple verification with Meytec RX 475 mV redox calibration solution can be integrated into regular pool maintenance to confirm that the probe and meter are still performing correctly.
- Rinse the orp probe with clean water and gently dry with a soft cloth.
- Pour a small amount of RX 475 mV solution into a clean container.
- Immerse the probe in the solution and wait for the reading to stabilise.
- Compare the displayed value with 475 mV and adjust if the instrument allows calibration.
If the reading remains far from the reference value or is unstable, the probe may require cleaning, regeneration or replacement to restore reliable redox measurement.
Storage and handling recommendations
To keep the Meytec RX 475 mV redox calibration solution bottle 60 ml within specification, it should be stored in a cool, dry place away from direct sunlight and heat sources. Good handling practices reduce contamination and help maintain the stated reference value for as long as possible.
- Always close the bottle tightly immediately after dispensing.
- Use only clean glass or plastic containers for the working volume.
- Never pour used calibration solution back into the original bottle.
Combined with regular probe cleaning, correct storage and periodic calibration using this Meytec redox standard, orp control systems can deliver stable and dependable disinfection monitoring throughout the swimming season.
