Measure the concentration of different substances in gases and vapours with Gas Detector Tubes.
Ready-to-use, thin glass tubes containing a matrix, combined with a reagant, that produces a distinct colour change when exposed to a gas sample. They are used together with a hand pump that will draw a sample into the tube.
A graduated scale is printed on the tube, so you can read the measurement directly on the tube
Over 600 types of gas can be measured.
- Beverage and brewing industries
- Health and safety programmes
- Lightweight GV110 Cylinder Pump is designed for use with almost all of the Gas Detector Tubes
- Gas Detector Tubes can readily be used in-the-field, factory or laboratory
- Each tube encloses a particulate matrix, such as gel or silica that binds a highly stable reagent
- A calibration scale is printed directly on the tube so that you can make a reading directly on the tube
- Tubes are hermetically sealed at both ends
- An extensive measuring range can be obtained by adjusting the sampling volume
- High precision – each production batch is independently tested and calibrated
- Conforms to regulatory standard JIS K 0804 for detector tubes
- GV-110 Gas Cylinder Pump – with tip breaker, pump stroke counter and flow finish indicator
- Gas Detector Tubes – over 600 available, see brochure under DOWNLOADS tab to select the type of gas and the range you wish to measure, eg ammonia or carbon dioxide
- Tube Tip Holder – detector tube tip breaker and storage receptacle for broken tips
- Safety Caps for Tubes – reusable rubber caps that can be attached to the broken edges of the detector tubes as an extra precautionary safety measure
- Smoke Tester Kit – makes the air flow in ventilation systems and ducts visible
- Extension Sampling Hoses – 5/ 10 / 30 m for measurements in tanks and manholes
- Extension Pole – for extended length measurements, 2.8 m
- Hot Probe – for measuring hot gases, such as exhausts and incinerators
How to use:
- Break off both ends of the detector tube. Insert the tube into the rubber inlet.
- Pull out the handle until it is locked. Wait until the sampling time has elapsed.
- Wait the required sampling time and read the measurement at the end of the coloured layer.
