Water Quality Analyzers

Water Quality Analyzers

Hangzhou Zetian Technology Co., Ltd. is the only company in China that has five analytical technology platforms including LED colorimetric platform, full-spectrum colorimetric platform, cold atomic absorption colorimetric platform, anode dissolution platform and electrode method platform. These five kinds of analysis platform can measure the common pollution factors in water, including COD, ammonia nitrogen, total phosphorus, total nitrogen and heavy metals such as copper, chromium, lead, zinc, mercury, arsenic, etc. At the same time, using the full spectrum colorimetric platform or anodic dissolution platform also can realize COD/ ammonia nitrogen integrated system, total phosphorus/ total nitrogen integrated system, and all kinds of heavy metal integrated system, etc.

The water quality analyzer equipment of ZETIAN have been experienced years of on-site validation, stable and reliable, low failure rate. Product details are listed below.
  • Peristaltic Pump Tube:
The United States imported special rubber hose, long service life, a tube can use more than one year.

  • Sample Module:
Homemade sampling module uses the high pure PTFE material, disassembly easy to clean or replace, reliable operation, every channel is completely isolated.

  • Control System:
(1) Control solenoid valve uses non-contact electronic switch, no mechanical life.
(2) Homemade control unit, after years of verification, low fault rate, high reliability, modular design, low maintenance cost.

  • Instrument Protection-Grounding Design:
Instruments have high-level intelligence, such as reagents fault adding warning (especially H2SO4 used in COD, if it is not H2SO4, it is likely to lead digestion tube burst), leakage protection (if there is a leak, the instrument will report en error), pressure relief valve (making pressure in digestion tube within a certain range).

All the external interface and main circuit of equipment is in isolation, which makes the normal sample without the outside interference. Especially for unequal potential connection, its effect is particularly evident.

In analog circuits (measurement module) also made electrical isolation, which makes the minimum possible interference on measurement.

  • Measuring Parts:
Modulating optical measurement makes no influence of external light on measurement, it is more stable.

  • External Interface:
The largest configuration has 2×4-20 mA output, 4×4-20 mA input, 2 switch input, 2 switch output, can access the PH meter, flow meter, ss and other equipment, and can display on the main interface.

  • Technology Platform:
It has five measuring platforms, suitable for the needs of different applications.
