水草情迷

1.用酒精(紅色液體)
2.電子
3.好似電錶咁樣,潛水的

邊隻最準尼??

2) > 1) > 3)

I personally never had a thermometer fail ever. I'll jsut get the cheapest available. I prefer 1) since if you have a good one (99.9%!), you don't have to worry if it goes bad, because it can't.

I don't have a scientific comparison. But will prefer number:

1. cheap
2. Stable, never worry about electronics failure, calibration, magnetic field, battery or power.....etc.
3. it very very seldomly fail...except you break it.

我用Hagen電子溫度計同酒精計,佢地相差0.5度不過電子式反應比較快

我又同意BEACHBOY的說法

Thx

咁電子溫度計邊隻品牌好呢??

Hagen大慨$70可測水溫同室溫
