Alpha-pH500 2-Wire LCD Display Transmitter
Product Features
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 3.8 mA 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.
