Growers appreciate the convenience of this tool. It is as easy to use as a rain gauge. Growers appreciate the convenience of this tool. It is as easy to use as a rain gauge. Patented ET Gauge is used by farmers, irrigation consultants, and government agricultural personnel in 23 countries. Rain entry is prevented by a check valve. Requires distilled water.

Tensiometer

A tensiometer in soil science is a measuring instrument used to determine the matric water potential ({\displaystyle \Psi _{m}}) (soil moisture tension) in the vadose zone. This device typically consists of a glass or plastic tube with a porous ceramic cup and is filled with water. The top of the tube has either a built-in vacuum gauge or a rubber cap used with a portable puncture tensiometer instrument, which uses a hypodermic needle to measure the pressure inside the tensiometer

Basic Soil Sampling Kit

These basic sampling kits provide all of the items needed to auger to a target depth as deep as 12′ and obtain a relatively undisturbed soil core sample. The kit is available in two sizes, 2 1/4″ or 3 1/4″ and with either signature series or 5/8″ threaded components. The kit comes with three different augers (regular, mud, sand) and enough extensions,to auger down to a depth of 12 feet. All of the components fit securely in a foam lined, poly-reinforced carrying case with,handles and wheels for added portability

Lab Oven

The universally applicable lab oven U is Memmert’s classic appliance for temperature control in science, research, and material tests in the industry.

Potable Water Level Indicator/ Sounder

Sounders. Electric water level meters – referred to as sounders – are frequently used in groundwater to measure level. These instruments are essentially tape measures with a probe on the end. Once the sensor contacts the water, it completes a circuit, causing an indicator to beep and an LED to glow. The water level depth can then be read on the tape.

Water distillation Apparatus
