Overview

RK500-12 pH sensor is a good solution to measure the pH value. It does not require a professional calibration instrument and is simple to operate. It can be used to continuously measure the pH value of wastewater. It is suitable for agriculture, sewage treatment plants, chemical industry, printing and dyeing, papermaking, pharmaceuticals, electroplating and environmental protection.

Features

• Low impedance sensitive glass film
• Temperature compensation for thermal stability
• Not easily hydrolyzed, eliminating alkali errors
• Simple operation and high reliability
• Internal signal isolation, strong anti-interference
• Widely power supply(7-28VDC)
• Low drift, small size, fast response speed
• Stable performance and long service life
• Easy electrode replacement

Applications

• Environmental protection
• Agriculture
• Aquaculture
• Water conservancy
• Sewage treatment
• Industrial wastewater treatment
