How to make water heating?

Question

Electronics

Good day,

there was a need to make water heating for electroplating. Bath 1.5 liters. The temperature should be regulated from 40 to 70 degrees Celsius. Preferably heat up quickly.

I have only basic knowledge in electronics.

I would like to get some advice on this topic, and maybe someone will have a link to solve the problem.

Thanks in advance for your replies

Answer 2

then everything is simple - we put the boiler, and on the thermometer we look at what kind of heating and turn it off when it reaches.
It can be more advanced - we buy a 500W boiler, put a dimmer (designed for 800W and above).
Next, we calibrate the scale in degrees for him, marking them on a thermometer.
During operation, you can immediately turn on the maximum, and when you reach, say, 70 °, set the regulator to this mark. as a result, it will even maintain the temperature.

Answer 3

Specify - do you need auto-adjustment or is manual enough to monitor the temperature using a thermometer?
those. Do you need to maintain the set temperature or do you just need to heat it up to a certain temperature?

Answer 4

about buying a boiler - if not in local stores, you can buy it on eBay,
look for the keyword - Heater Coffee for

Answer 5

If the environment is aggressive, then it is better to use an aquarium heater (glass bulb) as a boiler.

Answer 6

If you have basic knowledge in electronics, then buy: a heating element (at least a boiler), a thermocouple (or resistance thermometer) and a regulator (type TRM1, TRM500).

Answer 7

I did it like this

$(function (){
  $('.item').hover(
    function () {
      $(this.parentNode).find('.category a').css('background','url(/image/ico-catalog-bgr.png) repeat-x');
    },
    function () {
      $(this.parentNode).find('.category a').css('background','');
      
    }
  );
});

Answer 8

You either write everything in native js or jQuery, why mix $ and querySelectorAll?
About the passage through the elements in a cycle in such a task, I generally keep quiet.
Try like this:

var $links = $('.category a');

$links.on('mouseover', function(){
  $(this).closest('.category').find($links).css('background','url(/image/ico-catalog-bgr.png) repeat-x');
});

$links.on('mouseout', function(){
  $(this).closest('.category').find($links).css('background','');
});
