Caliph-RS

A simple tool to calibrate and convert pH measurements using a two point method.

License: MPL 2.0 License: CC BY-SA 4.0 Build

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:

$ caliph 3.97 10.2

-----------------
  Calibrating
-----------------
Slope   0.96308
Offset  0.18657
-----------------

Optional temperature argument:

$ 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:

$ 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:

$ 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

$ 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:

cargo install caliph

or

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Follow these instructions to compile cargo-outdated, then skip down to Installation.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 Clone the project $ git clone https://github.com/kbknapp/cargo-outdated && cd cargo-outdated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 Once complete, the binary will be located at target/release/cargo-outdated
