Pantech Instruments manufactures PH 2-wire Transmitter MODEL 873. Pantech Instruments is the manufacturer and exporters of Process Control Instruments. PH 2-wire Transmitter is designed to provide 4-20 mA DC signal on the same two wires which carry the 24 V DC power for measurement of pH. The transmitter is an ideal choice for on line pH measurement using any industry standard combined gas electrode. PH 2-wire Transmitter provides a current output signal capable of driving load up to 650 ohms. This allows pH measurement at a distant place from the control room all the time.
The temperature compensation is built in and the process temperature is measured by RTD. The compensation in the PH 2-wire Transmitter is provided over the complete range of 0-100 degree Celsius. The instrument can be calibrated throughout the range of 0-14 pH with a minimum span of 2 pH. The PH 2-wire Transmitter is available in field mounted housings with or without local digital display. The local 3.5 digit loop powered LCD display reduces the load capability of the transmitter to around 500 ohms. The transmitter is available in weatherproof or explosion proof housing.
