The ADP1000 connects to a probe that measures pH, ORP, or other properties of a fluid. It is useful in applications involving water quality or chemistry. A probe is required to use this Phidget (see Connection & Compatibility for probes). This Phidget connects to your computer through a VINT Hub.
This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:
| Product | Board | |||
|---|---|---|---|---|
| Image | Part Number | Price | Number of VINT Ports | Controlled By |
 |
HUB0000_0 | $30.00 | 6 | USB (Mini-USB) |
 |
HUB5000_0 | $60.00 | 6 | Local Network (Ethernet or Wi-Fi) |
 |
SBC3003_0 | $120.00 | 6 | — |
Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

The Phidgets pH/ORP Adapter can connect to one pH or ORP electrode that uses a BNC connector. The electrodes in the table below are all compatible with this adapter. If you plan on using your own electrode, we recommend that you contact Phidgets Support to determine if it will be compatible with this adapter.

The ADP1000 with a pH or ORP probe measures pH (0-14) or gets raw voltage input from the probe (±400mV or ±2V). For more accuracy, set the temperature of the solution in the software.
You can use your Control Panel to explore your Phidget's channels.
1. Open your Control Panel, and you will find the following channels:
2. Double click on a channel to open an example program. Each channel belongs to a differemt channel class:
In your Control Panel, double click on "PH Sensor Input":
In your Control Panel, double click on "Voltage Input":
1. Setting up your Programming Environment
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
See the Phidget22 API for your language to determine exact syntax for each property.
In the Phidget Control Panel, open the channel for your device and click on the 
icon next to the data type that you want to plot. This will open up a new window:
If you need more complex functionality such as logging multiple sensors to the same sheet or performing calculations on the data, you'll need to write your own program. Generally this will involve addressing the correct channel, opening it, and then creating an Event Handler and adding graphing/logging code to it.
The quickest way to get started is to download some sample code for your desired programming language and then search google for logging or plotting in that language (e.g. "how to log to csv in python") and add the code to the existing change handler.
The Change Trigger is the minimum change in the sensor data needed to trigger a new data event. The Data Interval is the time (in ms) between data events sent out from your Phidget. You can modify one or both of these values to achieve different data outputs. You can learn more about these two properties here.
The ADP1000 automatically converts raw voltage (from the pH probe) into an extremely accurate pH reading. For even more accuracy, you can set a Correction Temperature. The Correction Temperature corresponds to the temperature of the solution you are measuring (in °C). Here are a few examples of how temperature affects the output voltage of a pH probe:
As you can see from the examples above, temperature has a greater impact on solutions that have a pH further away from 7.
If you want to monitor the temperature of your solution, you can use a thermocouple. Check out our Thermocouple Interfaces to get started. For more information about how to set a Correction Temperature, view the Phidget22 API.
When the probe dries out, it becomes more sensitive to interference. Even static electricity on your clothes can warp the reading. To solve the problem, immerse the probe in a buffer solution overnight.
See the PH/ORP Sensor Primer for more information.
