TESTORYT Absorbing Fluid
BRIGON-O2-Indicator TESTORYT is supplied filled with testing fluid. Absorbing fluid inside
TESTORYT has a shelf-life of about one year. Absorbing fluid in use inside TESTORYT is to be
replaced from time to time to ensure greatest degree of accuracy. Fresh TESTORYT Fluid will
absorb all CO2from approximately'300 samples containing 12% CO2. TESTORYT Fluid in
original refill bottles may be stored for several years due to the sealing of the bottle.
Replacing TESTORYT Absorbing Fluid
Remove the Tour screws, the metal cover ring, the seals and the entire valve assembly. Drain old
fluid from TESTORYT and rinse all parts in clean lukewarm water. Pour contents of refill bottle
into TESTORYT until fluid extends about 8 mm (1/4") into the bore of center Tube. Reinstall all
removed parts, draw the four screws down with light screwdriver force. When reassembling
TESTORYT, make sure all seals are dry and fit perfectly. Vent TESTORYT and set scale to zero
as described before.
Safety Precautions
TESTORYT Absorbing Fluid is corrosive to skin, clothing and some metals. Make sure to take all
safety precautions!
Keep out of children's reach! Keep refill bottles tightly closed. Do not eat, drink or smoke while
working. Avoid bringing fluid and acids together. Keep fluid away from metals and metallic salts.
Avoid contact with skin, eyes and clothing. In the event of a spill or accidental body contact with
TESTORYT-CO2-Fluid pay careful attention to the following.
External — flood with water and remove contaminated clothing.
Internal — administer or drink plenty of water.
Eyes — flood with plenty of water for at least 15 minutes.
In case of accident call physician immediately and show him these instructions or the refill bottle.
Aspirator Assembly
lt is important that Aspirator Assembly is air-tight and that air or gas is pumped only from Metal
Sampling Tube to Rubber Connector Tip. Defective Valves or a leaking Aspirator will result in
sample loss, with resultant loss of accuracy.
1. Check green Outlet Valve by sealing Metal Sampling Tube with finger, squeezing Aspirator
Bulb and release again. Aspirator Bulb should remain deflated.
2. Check red Inlet Valve by sealing hole in center of Rubber Connector Tip with finger. When
now squeezing Aspirator Bulb, Bulb should remain firm.
3. Filter Wool must be replaced when dirty or clogged. Use only BRIGON-Filter Wool as
replacement.
4. BRIGON-O2-Indicator TESTORYT and BRIGON-O2-Indicator TESTORYT are calibrated to
analyze gases which are saturated with moisture. Unsaturated gas samples will cause
TESTORYT to indicate slightly lower than actual gas concentration. If unsaturated gas is to
be analysed or if compressed gas standards are used to check TESTORYT accuracy, be
sure to saturate Filter Wool in Aspirator Assembly or to pump the dry gas over water.
