Use this set of 18 full color flash cards alone or as an addition to any macroinvertebrate activity. (Included in the Leaf Pack Experiments Stream Ecology Kit). The front of each card features a full-color photograph of a common macroinvertebrate in its natural environment. A list of dichotomous characteristics, a measuring scale, and detailed drawings on the back of each card aid in the identification process.

Helpful notes prevent confusion between macroinvertebrates with a similar appearance. A hole can be punched in the wide border of the laminated cards so they can be organized on a ring for field or classroom use.

A precision, NON-MERCURY thermometer, furnished in a protective plastic jacket with a window opening. Engraved graduations on white tubing increase the readability over the full range of -5° to 45°C in 0.5° increments.

Designed for the pool professional. The PockeTester™ measures the Sodium Chloride level in salt water pools with a range from 0 to 9,999 ppm; pH is measured 0.00 to 14.0 pH; TDS from 0 to 9999 ppm; and Temperature from 32.0° to 149°F. A memory feature saves up to 25 test results.

Measures five parameters including Conductivity, TDS, Salinity, pH, and Temperature using one electrode
Units of measure: pH, μS, mS, ppm, ppt, mg/L, g/L, °C, °F
Memory stores up to 25 labeled readings; auto power off and low battery indicator
Adjustable Conductivity to TDS ratio

This Alkalinity test kit provides total alkalinity readings only, using a Direct Reading Titrator. Testing range/sensitivity 0-200 ppm/4 ppm as CaCO₃.

This kit tests for Nitrate-Nitrogen using the LRC Comparator. Range/sensitivity is 0, 0.2, 0.4, 0.6, 0.8, 1.0 ppm NO₃-N.

This Salinity kit test for salinity using the Direct Reading Titrator method. Range and sensitivity is 0-40 ppt/0.4 ppt Salinity.
