About

This project contains two binaries:

caliph, for calibrating a pH electrode using a two point pH method.

conph for converting measured pH values to calibrated ones.

Demo

Once installed (see below), the two methods available are:

Calibration

When the temperature is 25˚C during the measurement:

```console $ caliph 3.97 10.2


Calibrating

Slope 0.96308

Offset 0.18657

```

Optional temperature argument:

```console $ caliph 3.97 10.2 -t 22.3


Calibrating

Slope 0.96828

Offset 0.16052

```

Boolean flat to save the calibration to calibration.ph in the current directory:

```console $ caliph 3.97 10.2 -t 22.3 -s


Calibrating

Slope 0.96828

Offset 0.16052

Saved to calibration.ph ```

Conversion

Assuming the calibration.ph file exists:

```console $ conph 3.5


Converting

Input 3.5

Output 3.5495

```

Custom calibration settings fof the slope and offset:

-c sets it to custom, -s VAL is for the slope, -o VAL is for the offset

```console $ conph 3.5 -c -s 1.1 -o 0.02


Converting

Input 3.5

Output 3.8700

```

Installing

The latest version of can be installed or updated with cargo install:

sh cargo install caliph

or

sh cargo install --git https://github.com/pdunne/caliph-rs

Binary releases will also be made available on the github page.

Compiling

Follow these instructions to compile cargo-outdated, then skip down to Installation.

  1. Ensure you have current version of cargo and Rust installed
  2. Clone the project $ git clone https://github.com/kbknapp/cargo-outdated && cd cargo-outdated
  3. Build the project $ cargo build --release
  4. Once complete, the binary will be located at target/release/cargo-outdated
