Meytec RX 650 mV redox calibration solution bottle 60 ml

Meytec RX 650 mV redox calibration solution bottle 60 ml

The Meytec RX 650 mV redox calibration solution bottle 60 ml is a high range reference liquid for calibrating and checking orp probes in swimming pools, spas and water treatment systems. It provides a stable potential around 650 mV so you can adjust electronic sensors and keep oxidation reduction potential readings accurate and repeatable.

High range redox reference

Orp probes gradually drift as the platinum surface and reference system age under the influence of disinfectants, salts and temperature changes. Calibrating or verifying with Meytec RX 650 mV redox calibration solution lets you correct this drift in the upper part of the measuring range, where strongly oxidising conditions are monitored and controlled.

A well defined 650 mV reference point is especially useful when you are running high disinfection levels or controlling demanding process waters. It helps you distinguish between real changes in water quality and simple sensor drift so that dosing decisions remain reliable.

Compact 60 ml bottle for mobile use

The Meytec RX 650 mV redox calibration solution bottle 60 ml is supplied in a compact screw cap bottle that fits easily into portable test kits and service cases. This format 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 650 mV calibration solution.
• Space saving bottle for field kits and service cases.
• Practical choice when you prefer fresh standards in smaller volumes.

For best preservation of the reference value, only the quantity needed for a single calibration should be poured into a clean container while the main bottle stays closed.

Calibration and verification of orp probes

The Meytec RX 650 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 at 650 mV or as a verification standard to confirm that probe response at high redox values remains within acceptable tolerance.

• High range reference point for orp and redox meters in oxidising conditions.
• Suitable for handheld testers, fixed controllers and multi parameter meters.
• Helps confirm that probes controlling chlorine dosing remain accurate.

Calibration and verification should always follow the procedure described in the instrument manual, including immersion depth, stabilisation time and any temperature compensation settings needed around the 650 mV reference.

Example high range verification procedure

A quick verification with Meytec RX 650 mV redox calibration solution can be integrated into regular maintenance to check that the probe and meter are still performing correctly in strongly oxidising water.

• Rinse the orp probe with clean water and gently dry with a soft cloth.
• Pour a small amount of RX 650 mV solution into a clean container.
• Immerse the probe in the solution and wait for the reading to stabilise.
• Compare the displayed value with 650 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 before it can provide reliable high range measurements.

Storage and handling recommendations

To keep the Meytec RX 650 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 high range Meytec redox standard, orp control systems can deliver stable and dependable disinfection monitoring in pool and water treatment applications.
