Biometer Top-Selling Semi Automatic Test Equipment Kjeldahl Nitrogen Analyzer

Product Introduction

It meets international / national standard, and adopts national standard Kjeldahl method: digest sample in concentrated sulfuric acid environment, steam distillation in alkaline environment, boric acid absorption, and indicator titration end-point color determination method.

Highlighted Features

◓ The distillation procedure could be finished automatically: automatic adding of water and alkali, automatic distillation, automatic power-off and sound reminding when the operation is finished;

◓ The authentic color LCD touch screen is equipped for the control of alkali adding and distillation time, and the condition can be stored;

◓ Adopting highly reliable & separate water adding pump and alkali adding pump;

◓ Water saving design: It is guaranteed that the circulating water flow-limiting valve open only during the distillation, automatically control circulating water flow , free from manual operation;

◓ 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 bellows pump uses the material of PTEF, which is highly reliable, anticorrosion against strong acid and alkali, and strong anti-blocking against particle. Under the control of stepping motor, the bellows pump is with stable liquid adding and free from the danger caused by negative pressure suction, which is the insurance of stable quality and long service life for the pump.

Meticulous Fault Self-diagnosis and Control Function

(1) It is guaranteed that the circulating water flow-limiting valve opens only during the distillation, which saves water without worry, and the circulating water flow is automatically controlled; reserved interface for automatic circulated cooling water machine is apply to dry conditions or water-saving laboratory;

(2) The separated specialized bellows pump is resistant to erosion and particle plugging with accurate measuring of the added acid and lye, and the interior is made of PTFE (Teflon); the added reagent is measured by volume without calibration, and the long lifetime is up to 5- 10 years (by end-users’ verification);

(3) Steam generator is equipped with pressure sensor, temperature sensor, temperature protection switch, water level double detection, and other protections like these;

(4) Distillation system is specially designed according to the rule of ammonia escape, ensuring highly reliable recovery rate, getting unanimous approval from national testing institution, and invited to draft national standard;

(5) Double distillation modes are optional;

(6) The digestive tube is specially designed to be surrounded by intelligent facilities, and the transparent acrylic cover is equipped for total protection.

(7) The panel is made of ABS engineering plastic, which is waterproof, electricity-proof and corrosion-proof.
