INDUSTRIAL TEST SYSTEMS

Industrial Test Systems multi-parameter strips cover a range of common water-chemistry parameters. Depending on the SKU, a single strip can test for pH, total alkalinity, total hardness, free chlorine, total chlorine, nitrite, nitrate, iron, sulfate, and other analytes. For example, MPN 481302 measures iron, nitrate, nitrite, pH, total alkalinity, and total hardness on one strip. MPN 481199 measures total chlorine and sulfate. MPN 480005 measures total alkalinity and pH. Because each SKU has a defined parameter set and detection range, the MPN should be matched to the specific tests required. Pack sizes vary by SKU, typically 25, 30, or 50 single-use strips.

Industrial Test Systems alkalinity strips are available with different ranges depending on the SKU. The multi-parameter strip MPN 480005 measures total alkalinity from 0 to 720 ppm and pH from 6 to 11. The combined hardness/alkalinity strip MPN 480115 measures total hardness and total alkalinity from 0 to 240 ppm. The chlorine/alkalinity strip MPN 480015 measures free chlorine and total alkalinity from 0 to 240 ppm. Because ranges differ by product, the MPN should be selected based on the expected concentration in the water being tested. Strips are intended for semi-quantitative screening; for numeric results at lower detection limits, a colorimeter is typically used.

Pack sizes for Industrial Test Systems strips vary by SKU. Common configurations include 25 strips per pack (e.g., MPN 481345), 30 strips per pack (e.g., MPN 480655 and MPN 480115), and 50 strips per pack (e.g., MPN 480015). Each strip is single-use. The pack count is listed in the product specifications for each MPN. When ordering, confirm the pack quantity and the parameter set, as some SKUs with similar parameters may have different pack sizes. 3G Electric can provide current availability and pricing for specific pack configurations.

Industrial Test Systems strips are dip-and-read, semi-quantitative tools: the user dips the strip, waits a specified time, and compares the color change to a printed chart. They require no reagents, batteries, or calibration and are suited to frequent, on-site screening. Colorimeters are handheld instruments that use a light source and detector to measure the color developed by a reagent reaction, returning a numeric result. They typically offer lower detection limits and better repeatability than visual strips, but require reagents, calibration, and battery power. The choice depends on whether a pass/fail visual check or a numeric value is needed. Both formats are used in cooling tower, boiler, and process water monitoring.

Industrial Test Systems strips are used for on-site water quality checks in cooling towers, boilers, and similar industrial water systems. Parameters commonly monitored in these applications include pH, total alkalinity, total hardness, nitrite, nitrate, and chlorine. For example, MPN 481345 measures total alkalinity, total hardness, nitrite, and pH, and is described for use in cooling towers and boilers. MPN 480009 measures nitrite and nitrate. Because treatment programs vary, the specific parameter set and range should be matched to the control limits for the system. Strips provide a rapid indication; for compliance or trend data, a colorimeter or laboratory method may be required.

Industrial Test Systems strips are supplied in containers designed to protect them from moisture and light. The container should be kept closed when not in use, and the desiccant pack should remain inside. Strips should be stored at room temperature and kept away from direct sunlight, high humidity, and volatile chemicals. Do not remove strips from the container until immediately before use. Avoid touching the reagent pads. Expiration dates are printed on the container; strips past their expiration date may give inaccurate results. Always follow the instructions provided with the specific MPN, as reaction times and reading windows vary by parameter.
