pH / ORP microprocessor transmitter, 4-20 mA - RS485 – Modbus, PH 3436 New

The instrument uses a pH/ORP sensor and RTD Pt100 temperature sensors. If the Pt100 is connected the transmitter makes automatic temperature compensation (pH only).

  • pH range: 0 ÷ 14.00 pH
  • ORP range: 0 ÷ 1000 / 0 ÷ -1000 / -1000 ÷1000 / 0 ÷ 2000 / 0 ÷ -2000 mV
  • Temperature range: -10.0 ÷ 110.0 °C / 14.0 ÷ 230.0 °F
  • Resolution: 0.01 pH, 1 mV, 0.1 °C
  • Digital output: RS-485 isolated
  • Analog output: 4-20 mA galvanically isolated, "current loop" two wires
  • Power supply: 9 / 36 Vdc
  • Dimensions: 71x95x58 mm. Rail Din (4 modules)
  • Operating temperature: 0…+50 °
  • EMC/RFI conformity: EN 61326
