Horizon Technology a Proud Partner of World Water Monitoring Day



We'd like to share with you, and invite you to participate in, a program we're proud to have become involved with — World Water Monitoring Day™ (WWMD). WWMD is an international education and outreach program that aims to build public awareness and involvement in protecting water resources around the world, by engaging citizens to conduct basic monitoring of their local water bodies.

The coordinators of WWMD are the Water Environment Federation (WEF) and the International Water Association (IWA), and the goal is to expand participation to one million people in 100 countries by 2012.

An easy-to-use WWMD Test Kit enables everyone from children to adults to sample local water bodies for a core set of water quality parameters including temperature, acidity (pH), clarity (turbidity) and dissolved oxygen (DO). Results are sent in and then shared with participating communities around the globe through the WWMD Web site.

The month-long program kicks off each year on September 18 with a data entry deadline of December 18. We hope you will embrace this opportunity and participate in World Water Monitoring Day. For further information please click here. To purchase one or more WWMD Test Kits click here.

DID YOU KNOW:

All You Ever Wanted to Know About Using Cap Adaptors

Since many glass sample bottles are made at high speed and low cost, some variances or imperfections may exist in the dimensions of the threads and opening between bottles of the same size and type. To remove this issue cap adapters have been designed for the various standard bottle diameters and threading, for example, 33 x 400 mm or 53 x 400 mm.

However, due to bottle variances from the manufacturing process, the cap adapters may not always give a tight enough seal. Without a tight seal, air may leak into the sample bottle causing sample overflows during the extraction process.

To avoid this we recommend using the gasket that comes inserted in each cap adapter. It may be possible to use the cap adapters without a gasket, and not encounter a leak, if you were using a bottle that had no imperfections at the threading or at the rim. Also, using a gasket with the 33 x 400 mm cap adapter is not always necessary, when used with a larger cap adapter, and not directly on a 33 x 400 mm bottle.

The point of this Did You Know, is whether a gasket should be used or not, depends on the quality of the sample bottles, and the imperfections that may exist which could result in variances from the standard. We recommend that you test sample bottles for leaks with, and without, gaskets and decide the best option to optimize equipment performance.
