Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
As shown in Figure 1-2, a kind of two-colour fluviograph of HTHP drum band filtering, including table body 1, the outer cup of table body 1
There is observation cover 2, the front of observation cover 2 is provided with peep hole 3, and peep hole 3 is staggered in two row, and the rear of table body 1 is provided with light source cover
4, light source cover 4 is interior to be provided with two kinds of light sources of feux rouges and green glow.
