The Citizens Soil Sampling Toolkit addresses the concerns of citizens who want to know what levels of chemicals are in their garden, in the surface of bare soil around children’s playground equipment and in their yards due to environmental toxins. These high-exposure areas are of concern due to potential health impacts. Our kit empowers residents to sample their own property and trains them in the use of established principles and protocols. CSCR then can help guide citizens in the interpretation of results and provide the tools to advocate for environmental health and justice.

Measuring power (in watts) in a low voltage (up to 50 volts) system.

The Watt meter is of simple design, consisting of 2 cheap multi-meters, the first connected up in series with the circuit to measure current, the second connected in parallel to measure voltage.

To use the watt-meter you connect the wires on one side (the left) of the meters to your power source and the other set of wires on the other side (right) to your circuit.

To find wattage you simply multiply the 2 number together, and voila the wattage!

The cost. If one can assume that the person building the Wattmeter is a hobbyist of some sort,
I would assume that he/she has a bunch of wire lying about, so the only cost would be in the meters.

You need 2! so that would be $11.98. BUT Harbor Freight always has these on offer at $3.99, sometime less. And once in a while, they give them away FREE. Yes you read that correctly FREE. In fact the total cost to me for the Instructable was ZERO. Don't you just love that number $0.00 !!!

Warning Dr Smith!!!!. Please read the warnings on the Instructable WRT plugging in the test probes, etc.

Notes:
WRT = with respect to
Harbor Freight is a tool supply company in the USA.
Any meter would do, these where chosen as they are very inexpensive, and the shape makes them easy to glue together.
In the photo, a small 3 AA cell battery is on the left, the meters are in the middle, and a simple LED circuit on the right.
With the LED light, the Voltage is 5.89 and the current is 0.01 Amps, giving a power of 5.89 x 0.01 = 0.0589 Watts
This meter has better accuracy when used with higher currents, such as 0.5 Amps or above.
The wires in the photo are different to the ones shown in the instructable, this type of wire (solid core) was chosen so it could be used with breadboards.

The LaMotte Tracer Pocket Tester provides a digital salinity reading of water. Various models offer additional tests as well such as salinity plus pH, TDS, or Temperature.

Review from Julie Vastine:

"We don't know how well they perform in brackish water but when we tested 11 meters under $200 for conductivity, the most accurate, precise, and volunteer friendly was the LaMotte Tracer Pocket Tester (~$100). We chose this meter to do baseline conductivity testing in PA streams (50-600 uS/cm) and capture potential shale gas flowback water (<20,000 uS/cm).

The data use goal was a regulatory red flag for state agencies to do follow up testing. It compares well with our lab bench top probe. It has three calibration ranges (84, 1413, and 12,800 uS/cm).

The salinity readings with the pocket tester uses a ratio conversion factor based on the conductivity values."
