The utility model belongs to the technical field of the test apparatus, a novel methyl alcohol content once only appears field test cup in white spirit is disclosed, be provided with unable adjustmentbase, unable adjustment base's middle part cartridge has the cup, the top cover of cup is equipped with the funnel body, the surface paste of cup has the trade sample colorimetric card, unable adjustment base's outside cover is equipped with the cutting ferrule, the inside hoist and mount of cutting ferrule have a plurality of test tubes body. This novel methyl alcohol content once only appears field test cup in white spirit simple structure realizes depositing methyl alcohol through a plurality of test tubes body to contrast through the trade sample colorimetric card, improved work efficiency, installation through the cutting ferrule realizes the protection to the test tube body, avoids the test tube body to receive the touching, disturbs detection effect, the reagent of selecing is gotto the accurate volume of test tube physical stamina, and the funnel physical stamina is fine puts reagent into the test tube body, can prevent that reagent from spilling.
