Precautions during use of pH sensor
by：BOQU
2023-04-15
Matters needing attention in the use of pH sensor The pH sensor needs to be calibrated regularly, and the calibration cycle is different according to the conditions of use. Generally, it is calibrated once every four to eight weeks. When calibrating, generally put the probe into two standard buffer solutions. The difference between the two standard buffer solutions is at least 2 PH. If the calibration fails, the probe needs to be cleaned. Generally, the probe is soaked in 1%-3% hydrochloric acid solution. 1-5 minutes, then rinse with water, wipe clean with a soft cloth. If grease is present, scrub with alcohol. Re-calibrate, if the calibration still cannot be completed, it means that the probe is damaged and needs to be replaced with a new probe. Probe life is generally 6 months to 3 years.
