HISTORY IS A HISTORY OF DETECTORKITAGAWA GAS DETECTOR TUBE SYSTEM started with a H2S tube for quality control
in year 1947 and has led a path in a field of gas analysis.

KITAGAWA GAS DETECTOR TUBE SYSTEMCOMPRISES OF「DETECTOR TUBES」AND「SAMPLING PUMP」
GAS DETECTOR TUBES
change colours when chemical reagnets filled in a glass tube
react with sampled target gas through the tube. The stain
created is proportional in length to the concentration of thetarget gas, so the concentration is read directly off the printed
scale on the tube. Kitagawa offers about 250 kinds of tubes
to measure about 400 different kinds of tubes and ranges.

AP-20 SERIESANTIBACTERIAL NONSKID GRIP

offers a hand fit easily and is light to pull.

A SHATTERPROOF DETECTOR TUBE

has 2-layer of films to protect from a breakage.
Even if broken, the inside reagents do not scatter.

(patent no.4100883)

SAMPLE FINISH INDICATOR

is easy to check the sampling completes.

● Designed and manufactured at certified factory by

ISO9001(Quality management system) andISO14001(Environmental Management System)● Japan design registration No.1131898● United States Design Patent No.US D467, 334 S

Gas to be measured

The concentration of the target gas is read directly off the printed scale or by using
a concentration chart packed in a tube box.

Tube No.

Tube numbers are listed in descending order of high concentration.
© after tube no. means the concentration is read by using a conversion chart.

Measuring range &No. of Pump Strokes

Measuring high concentration gas exceeding the measuring range of detector tubes
Collect a volume of sample gas into a glass syringe and dilute withfresh air. The tube reading is then multiplied by the ratio of dilution todetermine the actual concentration.

Glass syringe

Detector tube

Sampling pump

Measuring in an atmosphere under pressure or reduced pressure

If 100mL of gas is collected at a pressure that is two times atmospheric pressure, it is equivalent to 200mL of gas collected
at normal atmospheric pressure. When measuring at pressures other than normal atmospheric pressure, a pressure correction
is required. Therefore it is recommended to collect the sample in a gas sampling bag, then measure it at normal atmosphericpressure for more accurate readings.

SUBSTANCES TO BE MEASURED BY USING CONVERSION CHARTS
Conversion charts are available, upon request, for the following listed chemical substances using existing detector
tubes within the Kitagawa range. These conversion charts are for use in a temperature of 20°C/68°F.
Other conditions, such as different temperatures, humidity and coexisting gases, are not confirmed.
Please specify the name of the substance to be measured together with the tube number when ordering.

AIR FLOW INDICATORSTo check suction power, air ﬂow direction and speed of an air ﬂow from draft, duct, ventilation fans and hoodsby generating white smoke.
Air Flow Indicator Tube 301
Used with air flow indicators AS-1, AS-2 or AS-3. Air flow indicator tube has a film coating to avoid scatteringof reagents inside for safe check.
Complies with OSHA(Occupational Safety and Health Administration, UNITED STATES DEPARTMENT OF
LABOR)’S protocol for respirator fit testing(29CFR 1910 134 App A).

<CAUTION FOR USE>
Air flow indicator tube fills smoke generators in a glass tube. They react with vapour in the air and generate
white smoke. The white smoke generated includes toxic hydrogen chloride.
Pay attention to the following:•Do not breathe or touch the white smoke. The white smoke may irritate eyes, nose and throat.
If breathed, immdediately gargle. When smoke touches the skin, wash it off with water.
•The smoke corrodes metals or causes malfunction. Do not use near precision instruments.
•Do not use in confined spaces, crowded places or residential areas.
•Do not use in hospitals, food handling places or clean rooms.

<Tube no.301> includes;● Air flow indicator tube×10● Tip cutter● Cap×4

Air Flow Indicators AS-1/AS-2 (for continuous monitoring)AS-1 and AS-2 do not carry any heat sources so are an ideal for visual examine in explosionrisk areas.
AS-1 : Insert‌
the air flow indicator tube into the rubber bulb and squeeze the bulb togenerate the white smoke. One tube makes about 100 times smoke.
AS-2 : Insert‌
the air flow indicator tube into the inlet of the rubber bulb and squeeze the bulb
to generate the white smoke continuously by putting through an air-buffer in the air
reservoir. The white smoke continues for about one minute.

<AS-1> includes;<AS-2> includes;● Rubber bulb

● Rubber bulb and air reservoir● Carrying case● Carrying case＊Air flow indicator tubes are sold separately.

Air Flow Indicator AS-3 (for remote monitoring)
For continuous or intermittent air flow check where ventilation fan or hood is unreachable or located at confined
spaces up to 2 metres.

APPLICATIONS OF KITAGAWA GAS DETECTOR TUBE SYSTEM
INDUSTRIAL HYGIENE
Measures harmful gases and vapours quickly
in the atmosphere to control the concentrationin the work place.

PROCESS CONTROL
Measures impurities in gases as raw feedstock andintermediates to ensure high product quality and prevent
catalyst poisoning to improve production efficiency.

ON BOARD
Measures toxic gas before entering cargo rooms
or checks residual gas after cleaning chemicaltanks in conformity with the IMO rule.

COMBUSTION EFFICIENCY
Measures CO, CO2 and O2 in exhaust gas to checkcombustion efficiency of combustion appliances.

PREVENT ACUTE POISONING
Measures leaked, blowout, generated or residual toxic
gases rapidly to prevent poisoning.

DISTRIBUTED BY:

INDUSTRIAL WASTE WATER
Measures effluent simply and quickly to identify thesource of pollution anywhere.

FIRE/EXPLOSION PREVENTION
Measures mixed combustible gases speedily andsafely on-site without ignition source to prevent
