FAQ
1. Can your ORP pH meter realize dosing control?
A: Of course. The APX1-C2 controllers have two SPST relays. The setting objects include: alarms for high and low values of PH/OPR, alarms for high and low values of water sample temperature, and can also be set as a cleaning cycle for the sensor.
2. Does your controller have temperature compensation function?
A: The digital pH meter made by Daruifuno can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real time. When the working temperature of the instrument changes, the instrument will compensate the hardware changes caused by temperature drift accordingly, making the detection result more accurate. This is a patented technology.
3. Can your instrument achieve signal output?
A: The APX1-C2 PH meter has a two-wire RS485 interface, the communication protocol is standard MODBUS RTU, and it can support JavaScript Object Notation text data format. If you don’t need this feature, we also have a responsive model at a very nice price.
