MEJ-PH5019 Plastic pH Sensor is a new type of pH detection equipment based on plastic materials, which exhibits unique advantages in performance and application. It replaces traditional glass electrodes with polymer materials, combines with a plastic matrix through an ion selective membrane, senses changes in hydrogen ion concentration in the solution, and outputs the pH value through a conversion circuit.
Characteristics:
Zero potential point: 7 ± 0.5 pH
Slope: > 98%
Installation size: 3/4NPT
Pressure: 1 ~ 3 Bar at 25 ℃
Temperature: 0 ~ 60℃ for general cables
Intro to The MEJ-PH5019 Plastic pH sensor
Plastic pH sensors exhibit significant advantages in many aspects due to their material and structural properties, as follows:
Low cost: Based on polymer materials, compared to traditional glass electrode materials, the cost is significantly reduced, making it suitable for large-scale mass production and widespread application.
Excellent flexibility: The plastic material endows the sensor with good flexibility, allowing it to fit complex curved surfaces for measurement, and is suitable for pH value detection of special shaped containers or irregular surfaces.
Strong mechanical performance: resistant to impact and drop, not easily damaged during transportation, installation, and use, able to withstand a certain degree of external force, and adaptable to harsh working conditions.
Good environmental adaptability: high chemical stability, acid and alkali corrosion resistance, can work stably for a long time in harsh environments such as high temperature and high humidity, and has a long service life.
Excellent integration: easy to integrate with microfluidic chips, flexible circuit boards, etc., helping to develop miniaturized and portable detection devices to meet the needs of rapid on-site detection.
Wide range of innovative applications: It can be combined with flexible electronic technology to expand into emerging fields such as wearable health monitoring, soil in-situ detection, and real-time monitoring of food freshness.
