A laboratory range of borosilicate glass Meterate tubes with linear or direct reading scale giving water flow measurements. Clear indelibly fired-in markings and yellow backing give ease of reading. The tubes are made of heat-resisting glass with heavy walls and are supplied with plain ends. The plain end tubes can also be fitted into an anodised aluminium case which has an integral needle valve.

• Borosilicate glass tubes 150 mm scale length
• Accuracy ± 5% (full scale)
• Repeatability ± 0,25% of full scale reading
• Rib guided flow tube for maximum stability and accuracy
