Phys.) Dissertation (LPI, Leningrad, 1995). Changes in the concentration in the observed spectra allow aqueous solutions of electrolyte salts to be attributed to classical solutions.Ī. The positions of the peaks in the spectra are reliably reproduced and characterize the cationic and anionic composition of a solution. The observed dependences are of a pronounced spectral nature. A glass test tube with the considered solution of electrolyte salt is placed in the inductance coil of the circuit. Experimental results in the 50–1000 kHz range of frequencies are presented as dependences of the dielectric loss tangent on the logarithm of frequency ω of the excitation of an oscillatory circuit. All experiments are performed at room temperature.
Changes are recorded according to differences in tangent \(\tan \delta \) of dielectric loss, which reflects reactive processes in solution. Excavation mode puts more reception height and elevation information above grade for higher utilization in digging and staking applications.High-resolution low-frequency dielcometry is used to study changes in the structure aqueous solutions of electrolyte salts in the 10 −2–10 −6 М range of concentrations. Two clamp positions for cut/fill or excavation. Dust and weatherproof housing withstands a drop of up to 3 m (10 ft) onto concrete for reduced downtime. Multiple deadband setting allows adaptation to meet all your jobsite requirements. New CAPTURE function remotely captures and retains a measurement when the display is difficult to see. Simultaneous elevation LED's signal in low light levels and over a longer range for easier reading in poor light conditions. Anti-strobe sensor stops construction strobe lights from setting off the receiver, and makes it easier to identify true laser beam signals. Large 12.7 cm (5 inch) reception height acquires the beam quickly and makes it easy to stay in the beam. Features and Benefits: Digital readout of elevation - not only will high or low arrows be displayed, but the exact distance from grade will be numerically displayed, which eliminates the need to get "on-grade" to make measurements. The HL700 can be used as either a hand-held or rod mounted receiver for a wide range of applications. The HL700 offers a 3-year "No Excuses" warranty. The Laserometer is designed to survive the tough construction site conditions it is totally waterproof and can withstand a drop of 3 meters (10 feet) onto concrete.
An anti-strobe sensor prevents false readings from site strobe lights. A 12.7 cm (5 inch) reception height, more than double the industry standard, allows quick acquisition of the laser beam. Selectable units of measure can be displayed meeting your application - mm, cm, ft, in or fractional inches. Accurate measurements can be made without moving the rod clamp, saving time and increasing productivity. The readout is displayed on the large front and rear LCD's and shows exactly how far the elevation is from on-grade. The HL700 features a digital readout of elevation that provides a numeric display of +/- 5 cm (+/- 2 inches). The HL700 is an easy-to-use tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter.
