Distillation thermometers

The EQUINOX T-4 distillation thermometer is a WiFi thermometer with four probes, 0.01 °C resolution and a built-in pressure sensor. You can read the temperature on the colour display at the column or in the phone app, and you get an alarm when any probe crosses its threshold. Below we compare analogue, digital and WiFi thermometers so you can choose the one you really need.

Analogue, digital or WiFi - which distillation thermometer?

Analogue thermometer Digital thermometer with probe EQUINOX T-4 WiFi thermometer
Reading scale at the column display at the column colour display at the column and a phone app
Number of probes 1 usually 1 4 detachable probes (2 × 2 m, 2 × 1 m)
Resolution usually 1 °C usually 0.1 °C 0.01 °C
Alarm none depends on the model phone alarm for each probe
Atmospheric pressure none none built-in sensor with boiling point correction
Who it is for simple stills, reading on the spot when one probe is enough reflux columns, measurement at several points, remote monitoring

A cheap analogue thermometer is enough for a simple still. On a reflux column, changes of hundredths of a degree and measurement at several points at once are what count - and that is where a WiFi thermometer has the edge.

Where should the probes go in the column?

The four EQUINOX T-4 probes most often work at the same points as in a column controller: boiler, buffer, plate and condenser. You can name each probe your own way, calibrate it and set a temperature alarm for it. An M8 screw and a pipe clamp make mounting easy. The thermometer fits columns with UFO, NIXON and Abratek-type heads as well as simple stills.

What temperature does alcohol distil at?

Ethanol boils at about 78.3 °C at a pressure of 1013 hPa, but this value changes with atmospheric pressure. The EQUINOX T-4 measures pressure and works out how much the boiling point has changed since it was switched on - so you can tell a change in the weather from a change in the column. A rising temperature at the top of the column during the take-off means the end of the hearts and the start of the tails.

Start-up in four steps

  1. Connect the temperature probes.
  2. Connect the power (a 5 V USB charger - a power bank will do).
  3. Connect the thermometer to your WiFi network and add it to your account in the app.
  4. Follow the process live, wherever you are. The app and updates are included in the price of the thermometer.

Want to control the heating element power too?

Add the power control module (two channels, 2 × 2000 W or 2 × 3500 W) or go straight for the thermometer + module set. When the temperature exceeds the alarm threshold, the heating elements switch off by themselves. Full column automation comes with the EQUINOX-RK.10 controller - you can upgrade the thermometer to it with an add-on module.
