KP-D2030TypeportableCODAmmonia nitrogen and total phosphorus analyzer

1、 Instrument features

1. Separating the digestion instrument from the measuring instrument does not affect the measurement accuracy. Temperature PID automatic temperature control and timing.

2. High performance ultra-low power 16 bit microcontroller, with instrument standby time of up to 6 months or more.

3. Time saving operation.

4. Cold light source and narrowband interference optical system, with good optical stability.

5. Data power-off protection function.

6. Each can save 30 standard curves and 199 measured values (including time tagged year, month, day, hour, minute, second measured values, absorbance values, and transmittance)

7. Equipped with a USB port, it can be connected to a computer for recording, reading, or printing stored data.

8. The host chassis is made of molded ABS material, with an IP65 design and good waterproof and dustproof performance.
