Overview
The LEICI DGB-421 Portable Water Colorimeter is a platinum-cobalt standard chroma method device that meets the GB/T 5750 standard and can directly read the chromaticity without the need for Reagents. It is equipped with a high definition LCD screen with clear display, supports zero-point calibrate and full-degree brate calibrate, and has IP65 Protection Rating for a variety of water quality testing scenarios.
Features
1. Adopt high definition LCD screen, display clearly.
2. Adopt platinum-cobalt standard chroma method, in line with GB/T 5750 standard.
3. Simple and convenient operation, no need for Reagent, directly read the chromaticity.
4. Measurement unit is PCU, corresponding to degree, Hazen, Pt-Co, milligram platinum/liter.
5. Support zero calibrated and full calibrated.
6. Data storage (a total of 200 sets), access, clear.
7. IP65 Protection Ratings.
8. Supports battery power and USB power.
9. Support automatic shutdown and battery prompt.
Principle
The instrument is based on the platinum-cobalt standard chroma method for measurement. The chroma of water samples is detected through an Optical inspection system, and the results can be read directly without the use of a Reagent. The Measurement unit is a PCU, which corresponds to a variety of standard units to ensure accuracy and convenience.
Steps
1. Turn on the instrument power.
2. Carry out zero-point calibrating and full-scale calibrating.
3. Measuring location of the water sample, read the excellence value directly.
4. Use the Data storage function to record measurement results.
5. Review or clear stored data as needed.
Notice
Make sure the instrument is properly calibrated before measurement.
Avoid use in extreme environment conditions to maintain the IP65 Protection Rating.
- Regularly check the battery level and charge or replace it promptly.
Clean the equipment promptly after use to prevent contamination.
When storing data, be careful not to exceed the capacity limit of 200 sets.
