Uniphos detector tubes + ASP-40 pump — short-term measurement of over 150 substances
Uniphos detector tubes work by colorimetry: a measured air sample is drawn through the tube, the filling changes colour, and the concentration is read from the length of the stain against the scale printed on the tube. The manufacturer offers over 250 tube types covering more than 150 substances and concentration ranges — from ammonia and hydrogen sulphide to benzene, toluene, ozone and carbon dioxide. The tubes are pre-calibrated and maintenance-free. The sample is drawn by the ASP-40 piston hand pump, which needs no power, and its built-in end-of-stroke indicator changes colour the moment sampling is complete — there is nothing to time.
Note: The tube is matched to the substance and the range — every type has its own ordering code. This is an indicative, short-term measurement; it does not replace continuous monitoring with an electronic detector. We confirm shelf life and storage conditions against the data sheet of the specific tube.
Key features
- Over 250 tube types — more than 150 substances and concentration ranges.
- Colorimetric measurement: the concentration is read from the length of the stain on the scale.
- Tubes are pre-calibrated and maintenance-free — nothing to calibrate.
- ASP-40 piston hand pump — works without power and without electronics.
- A built-in end-of-stroke indicator changes colour when sampling is complete.
- Sampling lines of 4 m and 15 m with a holder — take the sample from a safe distance.
- A separate tube type for each substance and range — we select them for your application.

This is a selection — the full list covers over 250 tubes, including benzene, chlorine, hydrogen cyanide, formaldehyde, xylene, oxygen, nitrogen oxides, phosphine, vinyl chloride and solvent vapours. Many substances have several tubes with different ranges — we select the right type and ordering code for what you measure and at what concentration.
Applications
Occupational health and safety, checking confined spaces before entry, chemical rescue and fire services, process control, laboratories, maintenance and service — wherever you need to confirm quickly that a specific substance is present and at roughly what concentration, including substances a multi-gas detector does not measure.
Frequently asked questions (FAQ)
How do detector tubes differ from an electronic detector?
A tube measures once and indicatively, at the place and moment the sample is taken. An electronic detector runs continuously and raises an alarm. Tubes are used where a specific substance has to be confirmed — especially one a multi-gas detector does not measure at all.
Do Uniphos tubes need calibration?
No. The manufacturer supplies them pre-calibrated and maintenance-free — the concentration is read straight from the scale on the tube. Electronic detectors, on the other hand, do need calibration.
Does a pump from another manufacturer fit Uniphos tubes?
The ASP-40 pump is designed for the whole Uniphos line of 5 mm tubes. The manufacturer covers the 7 mm KwikDraw tubes with a separate pump — which is why we select the pump together with the tubes.
Brand and service
Uniphos Envirotronic — SafeTech handles selection, delivery and advice on detector tubes and pumps for short-term measurement. The tubes themselves need no calibration and no servicing. If you also run electronic detectors, we carry out their calibration and service at our own station near Gdynia.
