Tsukuba Soken is the specialist for the air and water pollution. After the company was started up by several enterprising scientists, to resolve the environmental pollution issues, they have been engaging in the development of new equipment for air/water analyzing and consultation for the investigation, research and inspection for the solution of pollution.

We, Tokyo Future Style, Inc. are distributing "the Uni-meters", their unique potable air and water analyzer to the global market as their marketing and distributing partner.

Please refer to the following product explanation and if you have any questions, requesting price quotation and/or products detail such as kit insert, please don't hesitate to Contact us. And please also refer to their website for more information.

The Uni-meters

The Uni-Meters are a series of instruments developed by Tsukuba-soken for citizens to analyze air and water pollutants by themselves (with attached instruments and reagents).

The spuit (pipet with bulb) type colorimeter indicates in analog or in digital the values of concentrations of pollutants in solution, or values proportional to concentrations only by sucking the solution into the spuit.

MONTLE REHEARB

 

This is very convenient for analyzing a large number of samples quickly.

The test tuba type colorimeter with an attached light scattering meter indicates transmittance values. Each of three LED, (Red, Green and Blue), is selected by a switch according to the color of solution tested.

The items measured by the Uni-Meter are as follows:

Water pollutants ; NH4+, PO4-, total N, NO2-, Anionic surfactants, COD, Cr+6, Cl, Cu, Fe, As, etc.

Procedures of measurement

  1. (1) Put on the power switch 1
  2. (2) Set the two way color selection switch 3 to the correct side.
    Green color LED for reddish color solution and Red color LED for reddish color solution.
    For NO2, set this switch 3 to Green color LED side. (LED Light Emitting Diode Light source)
  3. (3) Suck uncolored Saltzman solution into the spuit 6. (Tap water can be used instead of
    Saltzman solution )
  4. (4) Adjust the zero adjuster knob 4 to make the μ-ammeter indicate Zero.
  5. (5) Set the sensitivity check switch 2 up side.
  6. (6) Adjust the sensitivity adjuster knob 5 to make the μ-ammeter indicate 50μA
    (full scale value).
  7. (7) Set the sensitivity check switch 2 done side and repeat procedure (4) (5) (6) two or
    three times until the indication stabilizes.
  8. (8) Make calibration by using the standard solution of various concentrations.
  9. (9) Then it is ready for use.
  10. (10) In the course of measurement check "Zero'" by sucking colorless solution or water
    and adjust zero with the zero adjuster knob 4.

Mini-sampler for monitoring air pollution

Structure

A "mini-sampler" is composed of an air tight plastic capsule with screw cap and porous polypropylene film at the bottom covered by a rubber cap and a piece of filter paper impregnated with absorbent reagent enclosed in it as shown in Fig.1.

Principle of measurement

The absorbent filter paper exposed in ambient air absorbs a particular air pollutant depending on the kind of absorbent reagent used.

Quantity of the air pollutant collected in the absorbent filter paper is proportional to the product of concentration of the air pollutant in ambient air and the exposure time interval. Quantity of the air pollutant collected in the absorbent filter paper is determined by a proper analytical method such as colorimetry or turbidimetry.

From quantity of the pollutant collected in the sampler we can calculate average concentration of the pollutant over exposure time by using a value of collection coefficient of the sampler and exposure time. The porous polypropylene film can pass through molecules of air pollutant and works for eliminating wind effect on the collection coefficient of the sampler. By this device reliable data can be obtained.

The value of collection coefficient of the sampler is determined experimentally by comparing the quantity of a pollutant collected into the sampler with the value of average concentration of the pollutant measured by a standard method.

LET US MAKE A GLOBAL AIR POLLUTION MAP BY WORLD NGOS

This is your "mini-sampler" for preliminary measurement in your country in order to prepare for the global action of much larger scale simultaneous air pollution survey by world NGOs scheduled on the Earth Day next year 22nd April 1992.

Procedures of measurement

  1. (1) Take off the rubber cap and hang the sampler by adhesive tape putting it to a wall side,
    a pole or a tree at the place where you want to know air pollution.
    Do not lose the rubber cap! We need it later.
  2. (2) Make sure that the absorbent filter paper is placed flatly on the micro porous
    polypropylene film at the bottom of the sampler.
    * This is necessary to get reliable data.
  3. (3) After 24 hours, put on the rubber cap again and keep the sampler in clean atmosphere,
    such as in a refrigerator or a sealed bag.
  4. (4) After measurement, send your sampler as soon as possible to the following address
    together with a record paper writing the necessary items.
