pH Controller (rH, pH)
MOSTEC offers you precise and reliable measuring technology for pH value monitoring and dosing for all requirements. Every pH controller in our range has been thoroughly tested by us so that you can always rely on a high level of functionality. We will be happy to advise you on your plans, projects and personal needs. We will work with you to find the right pH solution for you – from professionals for professionals.
pH/rH(mV)-controller type M4020
The highly compact pH/rH(mV)-controller type M4020 with USB logger has been developed for simple process control and monitoring applications. The ultra bright touchscreen IPS display is easy to read even from a distance. It can be operated smoothly and enables intuitive and uncomplicated use. The device has an internal Modbus master. In combination with the M3720 amplifier, inexpensive and long cables can be used. While using this combination the customer can conveniently (pre-)calibrate the pH electrode in the laboratory and does not have to do this on site.
- programmable
- very compact dimensions
- 2 limit contacts
- 2 programmable current outputs
- Modbus RTU Slave
- Modbus RTU Master for external pH-amplifiers
- USB data logger
pH/rH(mV)-controller type M4020R
The very compact pH/rH controller type M4020 was developed for automatic dosing or monitoring applications. The ultra-bright touchscreen IPS display is easy to read even from a distance, can be operated smoothly and enables intuitive and uncomplicated use. Very steep titration curves can be controlled with the control algorithm. The device has an internal Modbus master. In combination with the M3720 amplifier, inexpensive and long cables can be used. In addition, with this system, the customer can easily (pre-) calibrate the pH electrode in the laboratory and does not have to do this on site.
- PID controller for steep titration curves
- Programmierbar
- very compact dimensions
- two valve contacts
- two programmable signal current outputs
- Modbus RTU Slave
- Modbus RTU Master for external pH amplifiers
- USB data logger
pH/mV-controller type M3120
The pH/mV-controller type M3120 has been developed especially for applications which, until now, could not be monitored and controlled automatically due to cost.
- 2 alarm contacts
- for standard pH7rH sensors
- temperature compensation to 120ºC
- LCD display, 15mm, color adjustable
- programmable
- modbus (optional)
- USB - logger (optional)
- optical alarm contact
Measuring Amplifier for pH and Redox type M3720
The very small measuring amplifier for pH and Redox type M3720 converts the electrode signal to a 4…20mA 2-wire signal. The M3720 works with a resolution of 12 bit, is pre-calibrated and connected between the electrode and the signal acquisition instrument (e. g. PLC).
- 0...14pH, -1000...+1000mV
- output 4...20mA, 2-wire-technics
- modbus
- temperature compensation
- hold function
