A given fluid flows in the tubes while another one flows in the shell around the tubes. 1 1-pass 588310 2 4-pass 588311 3 pH Transmitter (HART) Features a one-channel Liquiline M CM42 transmitter from Endress+Hauser for pH, conductivity or oxygen measurement. A pH probe measures the electrochemical potential of a solution to determine its pH. The device displays the pH measured by the probe and has a 4-20 mA output to transmit the measurement to a controller. It uses the HART protocol, 4–20 mA. Order no. 588353 4 4 pH Transmitter (HART) Features a 4-channel Liquiline CM444 transmitter from Endress + Hauser for pH, ORP, conductivity, oxygen, chlorine, turbidity, and sludge level measurement, and more. It uses the HART protocol, 4–20 mA. Heartbeat 611546 5 Conductivity Transmitter Device that features a probe which measures the conductivity of a solution. The probe has a large measurement range and a high durability. The device displays the conductivity measured by the probe and has an output to transmit the measurement to a controller. Supports the HART protocol. Order no. 588355
