Brief introduction: Harvardhonors the launch of a new animal ventilator 683.In addition to the new smooth and beautiful appearance, the animal ventilator 683 has some new improvements.The animal ventilator 683 is used for small animals of 250g to 10Kg.Such as rats, hamsters, rabbits, cats, dogs, etc. Features: Able to monitor PEEP The new pipe cutting connector can easily adapt to different sizes of pipes The volume scale of permanent etch on cylinder will not wear out Volume and velocity controls are linear The animal ventilator 683 has two piston and cylinder assemblies, with small allowable volume increments of 0.5 -- 5cc and 0.5cc. Large increments from 3-30cc, 0.3 cc. The tidal volume can be set more accurately by calibration. The digital LED panel shows the respiratory rate, which can be set 18-150 times/min. Adjust the volume and speed during the operation of the ventilator. The animal ventilator 683 has four air inlet and outlet ports: instrument inlet, animal inlet, animal outlet, and instrument outlet. Respiratory function control PEEP, which is necessary for animals to use ventilators for a long time.
