pH transmitter that achieves both high precision and reliability.
pH transmitter that converts the output from a pH electrode or Redox electrode into a temperature-compensated 4-20mA analog signal, insulated from the electrode's input circuit. The LCD display can show the process signal values and various parameters. High-quality product design and the use of selected components enable long-term, high-precision, and reliable measurements. It can be used in combination with separately sold pH electrodes or Redox electrodes and a temperature probe (Pt100Ω/0°C). ▼ DC 4-20mA output pH meter ▼ Relay output (delay setting available)
