Handheld Rapid Water Quality Tester

Adopted or referenced standards

• COD was determined using the rapid digestion spectrophotometric method according to HJ/T 399-2007 .

• Ammonia nitrogen was determined using the Nessler's reagent spectrophotometric method (HJ 535-2009 ) .

• Total phosphorus was measured using the ammonium molybdate spectrophotometric method (GB/T 11893-89).

• The residual chlorine, total chlorine, and chlorine dioxide residues shall be tested in accordance with GB/T 5750.11-2006 and the requirements of the 20th edition of the U.S. Standard Examination Method for Water and Wastewater.

Features

Multi-parameter, multi-range:

It can measure multiple ranges of parameters such as COD , permanganate index, Nessler ammonia nitrogen, salicylate ammonia nitrogen, total phosphorus, total nitrogen, residual chlorine, total chlorine, chlorine dioxide, ozone, nitrite, nitrate nitrogen, hexavalent chromium, total chromium, total iron, ferrous iron, copper, manganese, nickel, zinc, cobalt, aluminum, silicon/metasilicate, sulfate, cyanide, turbidity, color , total hardness, and total alkalinity .

convenience

Users can create new curves using the dilution factor method.

Curves can be imported via Type-C interface

Curves can be input by entering K&B values, etc.

consistency

The light source is calibrated before leaving the factory to ensure the consistency of measurement indicators.

Multiple sample cells

Φ25mm/10mL colorimetric bottles are used for the detection of indicators such as turbidity, color, and hardness.

Φ16mm digestion colorimetric dual-purpose tube adapter for the detection of pre-prepared reagents.

Multiple light sources

Different light sources are built-in to meet different performance requirements, with a maximum support of 12 light sources.

Low power consumption (built-in 18650 rechargeable battery)

Using an LED light source, no need to replace the light source during long-term testing.

Built-in backlight, which can be manually turned on or off.

Massive storage

It can store no less than 100,000 test data records and provides host computer software for easy export and retrieval.

Compatibility: Compatible with reagents from different brands

Portability: It can be held in the palm of your hand, completely under your control.

Equipped with a portable digester, a testing box, and testing accessories, it can be widely used for various on-site tests.
