Resolution: 0.01PCU
Basic error: ±3%(F.S)
Repeatability: ≤3%
Optical stability: The absorbance value of the instrument drifts less than 0.002A within 20 minutes
Dimensions: host 266mm×200mm×130mm
Weight: 1kg
Normal use conditions:
⑴ Ambient temperature: 5～40℃ ⑵ Relative humidity: ≤85%
⑶ Power supply: AC(220±22)V; (50±0.5)Hz
⑷ No significant vibration and electromagnetic interference, avoid direct sunlight.

Using high-performance, long-life (100,000 hours), high-brightness light source, coupled with a narrow-band filter system, the optical stability is strong, and it is not easily disturbed by various lights, so the instrument has high precision and good stability.
Large-screen LCD Chinese display, Chinese menu operation, simple and intuitive.
The measurement data can be stored permanently. In addition to the factory calibration curve, the working curve also has the user's own calibration curve.
The casing of the host machine is made of molded ABS material, which has good corrosion resistance.
Using high-performance, low-power 16-bit single-chip microcomputer system, the performance is good.
More than ten years of experience in the production of water quality monitoring instruments to ensure product quality.
