Description

The Dual Incubator, designed for microbiological water monitoring via detection of indicator organisms for E. coli, cholera, salmonella and other faecal water borne pathogens, is the most popular portable water testing system in the developing world.

The Dual Incubator comes with a separate battery back and can test up to 32 samples at once.

The Oxfam-DelAgua Dual Incubator Kit was developed by scientists at the University of Surrey in collaboration with colleagues at Oxfam. It is designed to help provide information about the safety of water supplies in difficult situations or remote areas where laboratory facilities do not exist.

Designed to carry out five basic tests to measure the quality of drinking water, (microbiological quality, turbidity, free chlorine, total chlorine and pH), the kit is primarily used in the field, but may also be used in a laboratory or other permanent location. The kit can also be supplied with a range of accessories and upgrades that will increase the scope of your water quality monitoring.

It comes in a Pelican Case for easy of carrying and durability.

Critical Parameter Tests

The kit will perform the following tests:

Thermotolerant (faecal) Coliform Count
The kit includes a portable, battery-powered incubator capable of making five cycles of incubation without mains electricity, generator or vehicle power. Thermotolerant (faecal) Coliform counts can be obtained within 14 to 18 hours of sampling giving a reliable indication of sanitary risk without need for transport or laboratory facilities.

Turbidity Test
A measure of the amount of suspended matter in a water supply. Suspended material may consume chlorine disinfectants and require treatment before disinfection.

Chlorine & pH Tests
Many emergency water supplies are dosed with chlorine disinfectant to ensure their safety as drinking water. These tests allow rapid assessment of chlorine levels and aid the efficient control of dosing thereby avoiding waste and ensuring that enough chlorine is present to safeguard the supply.

Other Tests
A conductivity meter is provided as an optional component of the kit. Conductivity provides an indication of contamination e.g. saline intrusion or sewage pollution. Additional equipment can be included on request to test for chemicals that may be of local importance.
