The digital compression testing machine with dedicated universal computer software for reading purpose, self operating & monitoring has been designed to meet the need for a simple, economic and reliable means to test concrete / cubes etc. For its compressive strength. The design expressive of simplicity, both of construction and operation, makes the machine easy to use and maintain. The unit is compact, making it useful for site and
Laboratory applications.

Features:
•High stability four pillar load frame.
•Each frame tested for stability and alignment to avoid tension failure during a test and to ensure centre loading.
•A precise large diameter spherical upper platen for optimum results.
•Motorized hydraulic power pack or pumping unit with rapid approach and automatic over load protection.
•Comes standard with safety guards on all four sides

The complete unit comprises a loading unit which is of four pillar model construction having a cross-head with a spherical seated platen. The lower platen is attached to the top of the piston. The loading capacity is of 2000 kn, cubes up to 200 mm & cylinders up to 150 mm dia x 300 mm height can be tested using the appropriate spacers.

Pumping unit attached to the loading unit by high pressure hydraulic flexible hose pipe. The pump facilitates rapid approach of the platens for daylight closure and also provides comprehensive control over the application of load.
A control valve provides fine control over the loading rate for accurate pacing.

Maximum load is held and retained for approx. 15 min, unless cancelled, using the panel mounted reset switch. Pace rate set for running the test can be maintained manually.

Product description: Surface runoff is the flow of water that occurs when excess water from rain, meltwater, or other sources flows over the earth's surface. This might occur because soil is saturated to full capacity, or because rain arrives more quickly than soil can absorb it. Surface runoff is a major component of the water cycle. It is the primary agent in soil erosion by water. QT series tipping bucket flowmeter can be used to monitor no-pressure, low-head, and small discharge flow of surface or underground runoff.

Product description: QT-PICO can be used to rapidly measure soil moisture in the upper layer, it can also work with extension rod to measure deep soil moisture. After calibration, it can measure soil salinity at the same time.
Principle

QT-PICO soil moisture and temperature meter is based on TDR (Time domain Reflectometry) technology. It can directly measure the dielectric constant of soil or other media. According to the relationship between the dielectric constant and soil moisture, soil water content can be derived from the output voltage.

When the meter is operating, it first produces 1GHz high frequency electromagnetic waves, then the waves transmit along the conductor and generate an electromagnetic field around the probe. When the waves reach the end of the conductor, they return to the source. The duration of transmission is between 10 ps and 2 ns. The meter is very sensitive and it can detect the time signal as short as 3 ps. The time sampling method makes soil moisture measurements become more accurate and convenient.

Product description: QT-ML3 portable soil moisture/temperature meter can be used for the measurement of moisture of various types of soil and media, and it can be used as a basic tool for on-site observation or mobile measurement.
Principle

Using FDR (frequency domain reflectometry) principle, the sensor emits electromagnetic wave with a certain frequency, the waves transmit along the probe till they reach the bottom of the probe and return to the sensor, the output voltage is recorded. Because the dielectric constant of the soil usually depends on the soil moisture, the soil water content can be calculated according to the relationship between the output voltage and soil moisture.
Feature

GPS coordination can be recorded
Record data Automatically or manually
Wireless data transmission via Wi-Fi
Recognize sensors by two-dimensional code
Automatically recognize connected sensors
Terminal memory card is up to 32G
Display real-time data and curve of recorded data
Export data to Excel for analysis

Product description: a reasonable assessment of water balance and evapotranspiration is an important part of hydrological cycle; a lysimeter is a useful tool to evaluate the use of water in the soil, water storage and transfer in the same location. Qt-3051 series lysimeter can apply to laboratory for the study on parameters relevant to water balance.
To make calculation easy, the height of column barrel of this system is designed to 300 mm, 600 mm, 1200 mm respectively, other height can be customized. The system uses state-of-the-art high-resolution weighing system, high-precision soil moisture and water potential sensor to ensure the accurate measurement of the entire system.

Applications

The lysimeter system can be used in many area, such as water characteristic curve, ecological restoration, small-scale simulation experiment, fluidity of soil water, soil mass transfer, soil absorption and buffering, water balance analysis, leachate analysis, groundwater recharge analysis, mass migration, material transformation research, farming method research, climate research, energy balance studies, correction of simulation experiment, water flux studies, simulation studies on groundwater recharge, determination of the leachate and so on.
