TOA DKK’s Innovative Analytical Instruments

TOA DKK

Innovative Measuring Instruments

AZ Science is a distributor of TOA DKK Corporation, a leading Japanese manufacturer of measuring instruments, and responds to the analytical and measurement needs of theThai market.

We will introduce an overview of TOA DKK and some key products.

1. About TOA DKK

TOA DKK is a COMPREHENSIVE measuring instrument manufacturer that provides various analytical instruments based on "Water / Air / Health / Gases" as our business pillars.

They offer an innovative range of products that are particularly useful in the fields of environmental monitoring and quality control which has high demand in the Thai market.

2. Measurement Items

pH, ORP, electrical conductivity (resistivity, concentration), dissolved oxygen, residual chlorine, turbidity, color, SS concentration, various ions, nitrogen/phosphorus, organic pollutants (COD), multi-item water quality measurement, automatic titrator, nitrate/nitrite, dissolved hydrogen, ozone 

3. Introduction of Products 

(1) Portable multi-item water quality meter WQC-40

The WQC-40 is a multi-function portable water quality meter that can measure up to 9 items simultaneously, enabling fast and accurate data acquisition in environmental surveys, wastewater treatment, and river monitoring.

Main features

• Up to 9 items can be measured simultaneously :

    pH, electrical conductivity, turbidity, temperature, salinity, TDS

    (total dissolved solids),seawater specific gravity, dissolved oxygen, ORP,

    ions (F-, Cl-, NO3-, Ca2+, K+, NH4+)

• Continuous measurement is possible at a depth of 100m.
• Standard sensor module diameter is 45 mm.
• Modbus compatible
• Data memory function (9999 data)
• Durable "waterproof and dustproof design" (IP67 compliant)
• "Lightweight" which can be carried easily 
• "Simple operation" which the beginner can use easily

(2) Salinity analyzer　SAT-500

The SAT-500 uses coulometric titration (end point is potential difference detection) to measure salinity based on chloride content.

It is designed for easy and accurate measurement of salinity in food processing, agriculture and marine research.

Main features

• Simple operation-just inject the sample into electrolyte in dedicated beaker
• Rapid measurement of about 25 seconds from the start of measurement to the        data out  with 1%NaCI standard solution
• Approximately 100 or more "continuous measurements" are possible with 1% NaCl     using the 20μL dispenser, and approximately 50 "continuous measurements" are     possible with soy sauce using the 2μL dispenser.

(3) Automatic titrator  AUT-801

The AUT-801 can handle a variety of titration methods by changing the titration unit and can meet the analytical needs in a wide range of fields, including food, chemistry, plating, electricity, steel, metals, environment, pharmaceuticals, and cosmetics.

Main features

• Various types of titration

       Acid-base titration, oxidation-reduction titration, precipitation titration,

    chelating titration, non-aqueous titration, electrical conductivity titration

• Two-series simultaneous titration and display

    Two different types of simultaneous titration, such as neutralization titration and

    oxidation-reduction titration. Simultaneous measurement of pH and

    neutralization titration. By connecting two sets of the multi-sample measurement      devices "turntable", a dual system of simultaneous titration can be set up.

• High-precision design that minimizes the variability of results.
• "Semi-auto function" shortens titration time.
• "Set detection point function" allows manual detection of the end point.
• Work efficient by connecting "turntables", "automatic sampling devices".

(4) Ion chromatograph　ICA-7000

The ICA-7000 is a high-performance ion chromatograph ideal for trace ion analysis.

It is used in environmental analysis, pharmaceutical research, and component evaluation of chemical products.

Main features

• All-in-one, compact design

    Same size for 2ch system

• Supports both suppressor and non-suppressor methods
• By adding an ion removal device (optional), highly sensitive analysis of anions      and cations is possible.
• Data processing is possible by using USB data communication, and the remote        operation is possible by using RS-232C/LAN conversion adapter.
• Automatic analysis of up to 90 samples by using auto sampler

     (When using device control software)
