TG 110 DL: General Purpose Fully Loaded Ultrasonic Thickness Gauge

At present the ultrasonic pulse velocity method is the only one of this type that shows potential for testing concrete strength in situ. It measures the time of travel of an ultrasonic pulse passing through the concrete. The fundamental design features of all commercially available units are very similar, consisting of a pulse generator and a pulse receiver. Pulses are generated by shock-exciting piezo-electric crystals, with similar crystals used in the receiver3. The time taken for the pulse to pass through the concrete is measured by electronic measuring circuits. Pulse velocity tests can be carried out on both laboratory-sized specimens and completed concrete structures, but some factors affect measurement: 1. There must be smooth contact with the surface under test; a coupling medium such as a thin film of oil is mandatory. 2. It is desirable for path-lengths to be at least 12 in. (30 cm) in order to avoid any errors introduced by heterogeneity. 3. It must be recognized that there is an increase in pulse velocity at below-freezing temperature owing to freezing of water; from 5 to 30°C (41 - 86°F) pulse velocities are not temperature dependent. 4. The presence of reinforcing steel in concrete has an appreciable effect on pulse velocity. It is therefore desirable and often mandatory to choose pulse paths that avoid the influence of reinforcing steel or to make corrections if steel is in the pulse path. Applications and Limitations. The pulse velocity method is an ideal tool for establishing whether concrete is uniform. It can be used on both existing structures and those under construction. Usually, if large differences in pulse velocity are found within a structure for no apparent reason, there is strong reason to presume that defective or deteriorated concrete is present.

We are offering thermoelectric gaseous attachment. in high volume sampler / reparable dust sampler provision has been made for simultaneous sampling gaseous pollutants. Here the air is passed through suitable reagents that would absorb specific gases where gaseous pollutant like so2, nox, cl2, h2s, cs2, nh3 etc. Are analyzed subsequently by simple wet chemistry method to determine the concentration of specific pollutant. During gaseous sampling it often happens that ice does not last for full sampling period due to high ambient temperature. As a result temperature of chemical reagents increases and it reduces absorption efficiency of gaseous pollutant. During high temperature even chemical reagents taken for absorption evaporates with time. Thermoelectric attachment sle-tga 143 has been designed to take care of such problems. It is provided with non wearing thermoelectrics / peltier system special features 1 provides 24 hours continuous cooling. 2 non wearing thermoelectrics (peltier eystem). 3 full polyurethane-foam lining. 4 brings down temperature by 10-25 deg g depending upon the ambient conditions. 5 easy to use even with high volume sampler or respirable dust sampler. technical specification flow rate 0-3 lpm measured using plastic body flow meter accuracy 2% full scale division power consumption 48 watts sampling train four inlet and one outlet manifold with built in needle valves for flow control of each in let absorber 4 nos.
