Kick-Net Only available (Order Code 0021 – $105.00).
Includes 2 Octa-Slide color bars with 8 translucent color standards for Chlorine and pH. A 50-page reference manual for entry level lifeguards and service personnel is included with information on water balance, sanitizers, dosage charts and testing. The POOL MGR. series also includes diagrammed instructions and saturation index calculator in a tough, blow-molded carrying case.
This Aluminum test kit measures aluminum in water using the Octa-Slide 2 Comparator. A pink to red color will form when aluminum reacts with Eriochrome Cyanine R, at pH 6. Range and sensitivity is 0-0.5 ppm Al3+.
In this Caustic Test Kit a sample is reacted with barium to precipitate any carbonates, then is titrated with a standard acid to the phenolphthalein endpoint. Range/sensitivity is 0-10%/0.2% NaOH.
This kit tests for low ranges of Nitrite using the Dropper Bottle method. Range/sensitivity is 1 drop = 50 ppm NaNO2.
A rugged field carrying case houses individual test kit modules and valuable handbooks to assist and supplement soil science studies. Each individual test module includes complete instructions, A Study of Soil Science handbook now available as a download, and all the necessary apparatus and reagents to perform 50 soil macronutrients tests.
A comprehensive introduction to the study of soil properties and nutrients. Includes the popular and easy-to-use soil sampling tube, soil sample bags, the Soil Texture Unit, and individual test modules for four important soil test factors (see Specifications).
Collect water samples quickly and easily! This newly designed horizontal water sampler allows water to be sampled at specific depths. A 20 meter calibrated line, marked at one meter intervals, is included. The clear acrylic tube allows a visual inspection of the sample prior to dispensing and holds approximately 1,200 mL of sample.
Send the weighted messenger down the line to trip the closing mechanism at the desired depth.
This kit tests for Turbidity using the drop count method. Range and sensitivity is 5-100 JTU/5 JTU, 10-200 JTU/10 JTU.
Ideal for examining water quality in known or suspected polluted aquatic environments.
