YBOTECH K1306 fully automatic Kjeldahl nitrogen analyzer is widely used for the determination in the industries of food, feed, forage, pharmaceutical, soil, chemical industry, agriculture, forestry, material, environment monitoring and etc.
Feature
gradeCharacteristics
- Adding alkali and/or acid, distilling and titrating, titration buret waste removing, discharging, calibrating, fault detecting, solution level monitoring, and calculating can all be realized fully automatically.
- Titration color can be calibrated both automatically and manually. The titration endpoint is judged by the color signal collected by the high accurate 16-bit 3-primary-color digital signal color sensor.
- 2.0μL high-precision titrating system and professional unibody precision-work plunger are the assurance of the determination accuracy and operation reliability.
- The color LCD touch screen is equipped, with both English and Chinese operation interface available. The whole experiment procedure is real-time monitored and shown on the screen, and the condition can be auto-saved.
- Date Storage: As many as 1,000 sets of testing data can be fully stored.
- Not-in-position prompt of security door and digestion tube;
- Mature and stable steam generator technology is applied, automatic preheating, water supplying, steam pressure controlling, dry burning prevention, and cleaning can all be realized automatically.
- The steam pressure is automatically controlled within the safe range, thus danger caused by steam pressure is prevented.
- Double distillation modes are designed, both manual and automatic models can be randomly switched.
- Alkali pump adopts high-reliable PTEF bellows pump, which is anti-corrosion and anti-partical-plugging, stable during liquid adding, and free from the danger cause by negative pressure suction.
- Water-saving Design: Real-time monitoring of the circulating cooling water flow rate, warning reminder whenever the water pressure is lower than it is supposed to be.
- Distilling system is specially designed in accordance with Ammonia escaping rule, which is an insurance of the stable high reliable recovery rate.
- The digestive tube is specially designed to be surrounded with intelligentized facilities, and the transparent acrylic cover is equipped for total protection.
- Steam generator is equipped with pressure sensor, temperature sensor, temperature protection switch, water level double detection, and other protections like these.
