The utility model discloses a novel total nitrogen detection device which comprises a light source, an optical lens, a beam splitter, a first optical filter, a second optical filter, a first photoelectric sensor and a second photoelectric sensor, the optical lens is arranged between the light source and the beam splitter to converge light emitted by the light source and then emit the light into the beam splitter, and the beam splitter is used for dividing the converged light into two beams of light and emitting the two beams of light to the first photoelectric sensor and the second photoelectric sensor respectively. And the first optical filter and the second optical filter are respectively arranged between the beam splitter and the first photoelectric sensor and between the beam splitter and the second photoelectric sensor. According to the novel total nitrogen detection device, light rays are divided into two paths through the beam splitter, optical fibers are not needed, and the light path and the device a
