3、 Technical parameters
1. Host composition: Heating and digestion intelligent control system, automatic endpoint control system, refrigeration cycle system, nitrogen blowing control system, chlorine gas absorption device
2. Heating and digestion intelligent control system:
2.1 Using ceramic infrared radiators for heating, with good thermal conductivity as the heat source, independent temperature control, and uniform digestion.
2.2 Digestion unit: no less than 6 samples, single well single control, digestion temperature, timing time, nitrogen flow rate can be freely set, constant temperature circulation condensation, independent digestion of various samples.
2.3 ★ The conical tube digestion bottle is connected with a PTFE joint thread, which has good sealing effect and saves time and effort in installation and disassembly
3. ★ Automatic endpoint control system: high-precision nitrogen flow metering module, single hole single control, constant flow blowing, automatically stops heating when the set digestion time is reached, nitrogen flow automatically switches to static flow, and the state automatically switches to flow without personnel intervention.
4. ★ Detection range: (1000-50000) mg/L (calculated as chlorine) Anti chlorine interference: [Cl -] ≥ 50000mg/L No effect
5. COD measurement range: Water samples with COD ≤ 700mg/L (undiluted) and above 10mg/L, measured by dilution of the water sample
6. ★ Chlorine gas absorption device: It needs to be equipped with a chlorine gas absorption device, with sufficient reaction of the absorption liquid. The absorption device is located in front of the machine for easy operation!
7. ★ Refrigeration cycle system: Built in compressor cooling system, internal circulating water cooling, no need for external water source, it needs to have automatic one click water addition, and stop automatically when reaching the liquid level.
8. ★ Nitrogen blowing control system: adopts imported proportional valve, digital regulation of nitrogen flow rate, and automatic closed-loop control of flow rate according to pressure;
8.1 Nitrogen flow control range: (0-100) ml/min Control accuracy: ± 1.5% F.S Repeatability accuracy: ± 0.2% F.S.
8.2 Nitrogen automatic adjustment function: The nitrogen flow rate can work in different time periods and flow rates, and switch automatically!
8.3 Nitrogen flow rate conversion: Automatic high and low flow rate conversion without personnel intervention.
9. Temperature range: (0-450) ℃ (adjustable) Temperature control accuracy: ± 2 ℃
10. Time control: 0-999 minutes (adjustable) Heating time: 5-8 minutes
11. Intelligent operating system: Operated by an intelligent microcomputer, equipped with a 7-inch color touch screen, the display screen is fixed in front of the machine (machine appearance or relevant proof documents need to be provided), making it convenient for experimental personnel to operate, and the required parameters for the experiment can be set independently;
12. The host has a storage and printing function, and the experimental data can be checked!
13. Power supply: AC 220V, 50Hz Environmental temperature: 10-35 ℃ Environmental humidity:<60%
14. Instrument dimensions (length, width, height): 900mm * 470mm * 600mm
