pH, mV, dissolved oxygen, thermocouples transmitters
 


Transmitters for pH, dissolved oxygen, mV, thermocouples and others

For applications like water treatment, laboratory tests of water quality, measuring different properties of liquids it can be very important to have information about the pH, dissolved oxygen, temperature and other parameters. For the large percentage of all other applications it can be important to measure accurately small voltages, temperatures, flow rate, level and many other signals. And after measuring with a high accuracy the next important thing would be to transmit the data to a master that can evaluate all information, calculate and make decisions.

Our GpH140 series transmitters offer up to two pH inputs, up to two mV inputs that can be programmed to also accept 11 types of thermocouples, one Pt1000 RTD input and one 4-20 mA input. All with typical error of 0.03% FS and a great flexibility. Always available is also the built-in cold junction compensation with an absolute error of 0.2 oC.


pH + dissolved oxygen transmitter

GpH140-11 has two inputs with an extremely high impedance, specially designed to measure pH and / or REDOX / ORP.

GpH140-12 has one input for pH / REDOX / ORP and one for mV / thermocouples.

GpH140-22 has two inputs for mV / thermocouples.

All of them have as a standard one Pt1000 RTD input, the built-in cold junction compensation and one 4-20 mA two wire loop power input.


Isolated pH/ORP Transmitter with Universal Analog Output
Isolated pH/ORP Transmitter

GpH141 is a DIN rail mount isolated transmitter for pH/REDOX/ORP. It has one universal analog output that can be configured to active / passive, 0-20 mA, 4-20 mA, 0-5 V, 0-10 V, 1-5 V, 2-10 V. It needs 24 VDC (21.6 - 26.4 V) for power. No programming required, the device can be configured on the field in seconds by setting a couple of DIP switches only.


Isolated pH/ORP Transmitter with RS485 MODBUS RTU
Isolated pH/ORP Transmitter

GpH141-MB is a DIN rail mount isolated transmitter for pH/REDOX/ORP. It has an isolated 5V RS485 two wire port fully compliant to MODBUS RTU standard. It needs 24 VDC (21.6 - 26.4 V) for power. All programming is done over the communication port.
