  • New Design with Isolated Output - The alpha 500 series transmitter prevents output interference due to electrical noise or leakage from the input source. Cross talk between multiple transmitters in the same loop is also eliminated.

  • NIST or USA pH BUFFER options - alpha pH500 Transmitter allows user to select USA (4.01, 7.00 or 10.01) or NIST (4.01, 6.86 or 9.18) pH buffer standards during calibration.

  • Out-of-range Output Current Indicator - Monitor your process effectively using the optional out-of-range current indicator. When the monitored value exceeds the measurement range, the alpha 500 Transmitter indicates an out-of-range measurement by emitting a 3.8mA output current.

  • Hold Output Current Indicator - Use the optional HOLD output current indicator for your process control purposes. Configure the transmitter to emit the pre-set 22 mA output current to indicate ‘HOLD’ mode during calibration or set up mode.

  • Symmetrical Mode of Operation - Unique mode available in the Eutech alpha pH500, allow the transmitters to be operated in environments with electrical interferences. Simply configure the transmitter to the symmetrical mode and attach a potential matching pin.

  • Scalable 4/20 mA Current Output - Assign pH or ORP values at 4 and 20 mA for better resolved output at chart recorder or other peripheral devices.

  • Custom Dual Display LCD - Primary and secondary display are available for simultaneous display of pH, ORP and Temperature values. Allows instantaneous viewing of measured readings and transmitter set up configurations.

  • Easy Push Button Operation - Simply calibrate or adjust setup configuration with just a few touches of the buttons. The alpha pH500’s intelligent program in prompts respective buffers for easy calibration.

  • Temperature Compensation - Compensates variance in the measured readings due to temperature fluctuations, either Automatically (with Pt 100) or Manually (Process and Calibration temperatures can be set separately).

  • Panel or Wall Mount, IP65 Weatherproof Housing - The alpha 500 series transmitter has the flexibility to be mounted on the wall or in a control panel. In addition, the IP65 rated housing allows the transmitter to be installed outdoors or indoors. Mounting accessories are included for both types of mounting.

  • DC Voltage - Transmitters operate on a 12 to 24V D.C. power supply and multiples can be installed in a serial loop. Operations are not disrupted even if one of the transmitters requires service.
