Pen type PH meter electrochemical analysis instrument
The pen-type pH meter is a direct plug-in type. It is a portable pen-type precision instrument designed for on-site or field operation that can display both the pH value and the temperature value. This instrument is suitable for tap water source monitoring, aquaculture, environmental protection, printing and dyeing, electroplating, beverage industry and scientific research institutions to determine the pH value of water quality.
