- Getting the voltage varies on what you're using. The PH for this sensor is not at 0v for a PH7 it's around 2.51v from the multi-meter and PH4 at 3.03. If you calculate the step, 2.51-3.03 =-0.52. The difference between ph4.01 and PH7 is 2.99.
- If you're using a Particle product like the Photon or Argon, be aware of a bug. It's a hardware issue with the analog ports fluctuating a ghost voltage. This fluctuation is enough at these low voltages reading to make your ph sway by .7 or more. To fix this, you'll need to add a 0.1uF cap between the analog port your using and ground.
- This 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, which will shorten its life. There are two trimmers on the circuit board. One of them is for offset adjustment (closest to BNC connector) accomplished by removing the Ph probe and shorting the BNC connector with a wire. The other trimmer is an upper limit threshold for the digital output pin.

- Dissolved oxygen meter is a precision instrument for measuring dissolved oxygen and temperature. The dissolved oxygen probe is a thin film with a polarographic sensor and a thermistor for temperature measurement and temperature compensation. The permeable membrane separates the measured solution from the sensing electrode but allows oxygen to pass through the membrane to react, and the concentration can be measured.
- Dissolved oxygen refers to the concentration of molecular oxygen dissolved in water, generally expressed in mg/L (ppm) and saturation percentage (%), which is the percentage of dissolved oxygen in 1L of water. The oxygen concentration of our dissolved oxygen meter is 0.0-40.0mg/L, most of the range of dissolved oxygen meters on the market is 0.0-20mg/L. When measuring and calibrating, needn't open the protective cover of the electrode, just put the electrode in the solution for measurement.
- Detachable probe, easy to replace, equipped with 6 probe protective covers. The film inside the protective cover cannot be taken apart. After using for a period of time, the test value is inaccurate and the calibration is still inaccurate, and the membrane sleeve needs to be replaced.
- Adopts the digital screen display with backlight, which is more clear and convenient to read data. Auto power-off in 8 minutes if not using it. Low battery indication. Oxygen solubility will be affected by temperature, atmospheric pressure, and salinity. Our instrument with temperature compensation can meet normal use.
- It is very suitable for measuring the dissolved oxygen level and temperature in a wide range of aquariums, swimming pools, ponds, freshwater aquaculture, marine aquaculture, school teaching experiments, laboratory sterile environment, aquaculture, scientific research, and other fields.

FAQ:
Q: How do I install the pH sensor on my Arduino?
A: The pH sensor comes with 4 standoffs and screws. Use two of them for the Arduino. 1) Insert the base plate into the bottom portion of the housing. Keep in position with screws or hot glue. 2) Mount the pH sensor on the base plate. Secure to standoffs with screws.
Q: What is a pH regulator?
A: — The regulator is meant for reactions that start at a certain pH and naturally decrease/increase in pH due to the reaction. However, for many reactions, it is desired to stay at the starting pH. So, if the reaction deviates too far from the desired pH, this arduino project will pump in acid or base to bring the pH back to normal.
Q: What does the 0 mean in the pH value on Arduino?
A: The 0 represents a pH of 7.0. In order to be able to use it with Arduino this circuit adds an offset value to the value measured by the probe, so the ADC will only have to take samples of positive voltage values.
Q: How do you calculate the pH of a pH sensor?
A: The sensor is linear so by taking two points we can deduce the equation to convert the measured voltage to pH. The general formula would be y = mx + b, so we have to calculate m and b since x would be the voltage and y the pH. The result is y = -5.70x + 21.34.
