This kit tests for Sodium Nitrite using the Direct Reading Titrator method. Range/sensitivity is 0-1000 ppm/20 ppm NaNO2.

 

TesTabs® kit for measuring pH. Ideal for younger students and teachers who would like an alternative to liquid pH indicators. Ideal companion to Soil NPK Kit (Code 3-5880).

 

Determine turbidity or degree of visibility in natural waters with this weighted 20 cm diameter disk.

 

This kit tests for Tannin/Lignin using the Octa-Slide 2 Comparator. Range and sensitivity is 1, 2, 3, 4, 5, 6, 8, 10 ppm Tannin or lignin like substances.

 

A modification of the popular Low Cost Monitoring Kit, the Estuary Kit is specifically designed to provide simple, affordable and non-hazardous methods of testing saline and brackish waters for coliform bacteria, salinity, dissolved oxygen, nitrate, pH, phosphate, temperature, and turbidity.

 

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.

 

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.
