Caution on use

Safety Precautions

CAUTION
Precautions for chemicals
Handle the solutions used for calibration and measurements with care. Always wear protective gloves and eye protection when handling solutions. · Harmful in contact with skin and eyes. Rinse immediately with
tap water. · If accidentally swallowed, consult a doctor immediately.

Points of concern Do not give an excessive shock to the sensor cartridge. Cracked or chapped sensor cartridge can not be used. Replace such sensor cartridge with a new one. Immerse the sensor up to the sensor body under the nut. Use with the plug facing up and the membrane facing down as shown in the figure. The pH range is generally smaller when the concentration of the ions to be measured is lower. If the pH of the sample solution has exceeded the measurable pH range, accurate measurement may not be possible. Do not allow the liquid junction to dry out. If liquid junction is dried, measurement value may drift. Do not use (store) the sensor cartridge in any place where the operation temperature (storage temperature) is out of the specified range. Do not strongly place ion selective membrane against hard surface. Do not poke ion selective membrane with sharp object. Make sure the membrane has no dirt or air bubbles on it. Before the first use or if the sensor cartridge is less responsive, perform conditioning of the sensor cartridge before calibration. Soak a sensor cartridge in 100 mg/L or more standard solution for 1 hour. Always use new standard solution for calibration. Do not return a standard solution to its original container after it has been used once.
Check the firmware
In an ion sensor head (300-I) and a smart handheld meter (WQ-300) with the following firmware versions, there is no option to select an ion sensor cartridge. Then, it is necessary to update the firmware of the ion sensor head or the smart handheld to the latest version. Make sure to check before using an ion sensor cartridge.

Ion sensor head:

1.0.0

Smart handheld meter: 1.0.0, 1.0.1, 1.1.0

Refer to the instruction manual for smart handheld meter on how to check the firmware. It is possible that these firmwares will be updated from time to time as new functions and improvements are made. Check the following website for how to obtain the latest firmware and how to update the firmware. https://www.horiba.com/sgp/water-quality/support/ download-center/

Tips for accurate measurement Add the ISA to both standard solutions and sample
solution. The volume ratio shall be the standard solution
and the ISA = 50:1. Recalibrate sensor cartridge every few hours. Prepare standard solutions which have the following
concentration relationship for calibration.
Standard solution with low concentration < Sample
solution < Standard solution with high concentration Match the temperature of the standard solution in
calibration and the temperature of the sample solution in
measurement.

Note
Push the plug into the sensor head keeping connecters dry. Avoid using a rusted plug. In the absence of O-ring or in the case where the nuts is not
tight enough, liquids might flow into the connection space and cause malfunction.

Maintenance and Storage
Rince the sensor cartridge with pure water and wipe off the moisture. Attach the protective cap.
Replace sensor cartridge at the period whichever occurs first; approx. one year after purchase or approx. 400 hours of use, depending on sample solution, measurement frequency, and measurement environment.
Use up standard solution and ISA before the expiration dater displayed on the bottle.
Store the standard solution and ISA in a tightly closed bottle in a cool, dark place.
Disposal procedure
When disposing of this product, follow the related laws and/ or regulations of your country/region. It is possible to separate the cable part and the electrode part by cutting the cable (Figure below). The cable part is classified as plastic.
