Product Description

PH/ORP Meter



One set of PH/ORP measuring system contains transmitter, PH/ORP electrode, electrode mounting bracket and accessories. The structure of PH/ORP transmitter can be panel mounted, wall mounted and integral type.


PH/ORP transmitter converts electrode signal into standard electric signal, output 4-20mA analogue signal, upper limit and lower limit alarm control signal and digital communication. It will simultaneously display temperature, PH/ORP value, time and status.
PH/ORP transmitter and electrode are generally remote mounted, convenient for maintenance and disassembly of electrode. Integral installation is also available for some conditions.


HG111 Transmitter

1.    High intellectualization: using high accuracy AD conversion and single chip to achieve measurement of PH/ORP and temperature; automatic compensation of temperature; self-diagnose.
2.    High reliability and strong anti-interference; double high resistance input, photocoupling isolation output.
3.    Excellent display method: 192 * 64 dot-matrix graphic type LCD screen. Adjustable even back light, convenient for operation under dim conditions outdoors.
4.    Multi-parameters displayed on same screen: PH value, value of input mV (or output current), temperature, time and status, etc.
5.    Recorder function: historic data and trend curve traceable.
6.    Smart calibration: determine whether the electrode is stable or in failure in the buffer solution.
7.    Monitoring electrode: record available for each calibration, easy to query and analyze the law of change.
8.    3 types of calibration method: besides traditional 1-point calibration and 2-point calibration, you may manually input zero E and slope S.
9.    Output current setting and check: manual current source function may check and set value of output current.
10.    Control output programmable: can combine PH and temperature alarm control output mode.
11.    Instrument stable and not crash:  watchdog program ensures that the instrument works continuously without crashing.


HG113 Transmitter

Simple and practical functions, convenient and efficient operation, stable and reliable performance and superior cost advantage make HG113 greatly successful, widely used in various industrial areas, especially continuous monitoring of PH / ORP in sewage treatment industry.

1.    High intellectualization: using high accuracy AD conversion and single chip to achieve measurement of PH/ORP and temperature; automatic compensation of temperature; self-diagnose.
2.    High reliability and strong anti-interference; double high resistance input, photocoupling isolation output.
3.    Multi-parameters displayed on same screen: PH value and temperature. LED display module with high brightness; main display displaying pH value in 10*10 specification, eye-catching and visual distance far.
4.    Smart calibration: determine whether the electrode is stable or in failure in the buffer solution.
5.    3 types of calibration method: besides traditional 1-point calibration and 2-point calibration, you may manually input zero E and slope S.
6.    Control output programmable: can combine PH and temperature alarm control output mode.
7.    Instrument stable and not crash:  watchdog program ensures that the instrument works continuously without crashing.



HG117 Transmitter, 2 wire HART, Ex-proof, Remote / Integral

1.    High intellectualization: using high accuracy AD conversion and single chip to achieve measurement of PH/ORP and temperature; automatic compensation of temperature; self-diagnose.
2.    High reliability and strong anti-interference; double high resistance input, photocoupling isolation output.
3.    Smart calibration: determine whether the electrode is stable or in failure in the buffer solution.
4.    3 types of calibration method: besides traditional 1-point calibration and 2-point calibration, you may manually input zero E and slope S.
5.    HART or RS485 communication
6.    Instrument stability and no crash:  a watchdog program ensures that the instrument works continuously without crashing.
7.    High protection class: water resistant and dust resistant design, tight enclosure, application for outdoor use.

pH/ORP electrode is consumable. The main material is glass, which is easy to damage. Many factors may cause electrode failure. Electrode storage will also affects the service life, so it is not economical for each user to scatter inventory electrodes. We have a large number of various types of semi-finished products in the factory, making it easy to provide the freshest electrode and ensure that users do not have to wait for inventory.





Different mounting bracket types are available for different applications.

       HGS-A Submersible type
        HGS-B Insertion type
        HGS-C Telescopic type
        HGS-D Flow-through type
        HGS-E Simple sheath type
        HGS-F Measuring tank type

The selection of wetted parts material is mainly based on the corrosion of fluid, working temperature and pressure.
Two major categories of common materials:
Stainless steel: SS304 and SS316L
Engineering plastics: PVC, PP, PTFE, PFA, ABS, POM
