Precise aquatuner output temperature control

[biopon]

If you place a reservoir right after the output of the tuner, and place your coolant temperature sensor right after the output of the reservoir, you can achieve very fine control over the coolant's temperature within the reservoir itself.

In this build I aim for -182 degrees, and my variance is a tenth of a degree down, and half a degree up, with 460 kg coolant in the tank.

Sometimes you're better off just measuring the temperature of whatever you're cooling, but sometimes you need fine control over the coolant itself. In that case this helps a lot. If you use this, you need to aim to have a very short distance between the tuner and the reservoir. More liquid in the tank helps with finer control, but also makes the coolant temperature harder (slower) to sway.
