Feature:
1. QUICKLY RESPONSE TIME: The sensor module has quickly response time, low power consumption, convenient use and long use time
2. TWO TRIMMERS: There are two trimmers on the circuit board. One is to achieve offset adjustment by removing the pH probe and shortening the BNC connector with a wire(closest to the BNC connector). Another trimmer is the upper threshold of the digital output pin
3. PCB DOUBLE SIDED BOARD: Using 1.6mm thick PCB double sided board, sturdy and durable, possess long service life
4. LONG RUNNING TIME: PH value detection module come with large heat dissipation area, stable operation and long running time
5. PH0-14 DETECTION CONCENTRATION RANGE: Detection concentration range from PH0-14, detection temperature range is 0-80℃, analog voltage signal output method

Note:
1. Note that the buffer solvent needs to be purchased after purchasing the PH sensor (note that this is not sold and needs to be purchased locally, thank you).
2. The pH electrode probe must be calibrated with standard buffer solution before each use, and the electrode probe cannot be tested continuously for a long time, thus shortening its life.
3. If you are using granular products such as photon or argon, please pay attention. This is a hardware problem, the analog port will fluctuate with the ghost voltage. Under these low voltage readings, this fluctuation is enough to make your pH swing at 0.7 or above. In order to solve this problem, you need to add a 0.1uF cap between the used and grounded analog port.
