Geothermometer

Model : TH3-S

Measure the temperature of soil profile at different depth. Six temperature probes are 5, 10, 20, 30, 50 and 100 cm.

Water level meter

Model : Solinst water level troll 101

The distance between the water surface in the well and the ground surface is measured. The front end of the instrument equipped with a probe sounds when it touches water to obtain the depth of water table.

Submersible Pressure Transducer

Model : CS451

Measure water table by the pressure sensor converting the water pressure after recording the voltage and is used with the data logger.

Submersible Pressure Transducer

Model : Troll 400

Measure water table by the pressure sensor converting the water pressure after recording the voltage with data logger and battery built in TROLL 400.

Multiparameter Instrument

Model : Troll 9500

It measures the groundwater level and various water quality data, including chlorine degree, dissolved oxygen, nitrate and conductivity. It contains multiple probes, built-in data recorder and battery.

Vapor Sorption Analyzer

Model：Decagon Aqualab VSA

Using the dew point technique and vacuum dynamic aeration humidification or drying weighing technology to measure the water activity and moisture content simultaneously.  Providing complete moisture analysis, and isothermal adsorption curve.

Multi-sample Moisture Content Analyzer 

Model：Decagon TrueDry CV9

It can accurately and quickly analyze the moisture content of 9 different samples by using the direct controllable drying method. The instrument has built-in high-precision balance and can automatically detect the weight change of the sample in the heating process in accordance with AOAC, ASTM and ISO standards.

Water Potential Meter

Model：Decagon Aqualab WP4C

Dew point technique is used to measure the water potential. The electron beam is applied to the condensing point on the cold mirror and reflects to the photodetector. The change of light wii be analyzed. The thermocouple temperature sensor is connected to the cold mirror to record condensation temperature, and converts to water potential. In the case of known water content, we can draw the soil water retention curve quickly and easily.

Groundwater Modeling System (GMS)

Model：AQUAVEO GMS10.0 64-bit

GMS is recognized as the most powerful groundwater environment simulation software available in the market. It provides tools for characterization, model development, scaling, post-processing and visualization for each groundwater environment. GMS is capable of running 2D and 3D finite differentiation and finite element methods and supports MODFLOW 2000, MODPATH, MT3DMS / RT3D, SEAM3D, ART3D, UTCHEM, FEMWATER and SEEP2D models.

TOUGH2

Model：Lawrence Berkeley National Laboratory

TOUGH2 is a model for simulating fluid flow and thermal energy transfer in porous media. PetraSim for its graphical interface software, can support TOUGH2, TOUGHREACT and TOUGHFX, etc., and to assist users to simulate the results of the data visualization rendering.

PEST

Model：Echo Valley Graphics, Inc.

The PEST module is a model-rated software that minimizes the error between the simulated value of the objective function and the actual results to improve the reliability of the numerical model.
