John Morris Scientific is proud to introduce the new Isco 4700 Refrigerated Sampler for municipal and industrial wastewater applications.

The refrigerator features a powerful ¼ Horse Power compressor with software controllable temperature settings. The controller displays the sample compartment temperature and logs a 24-hour summary to confirm proper cooling and sample preservation.

For unequalled weather and corrosion resistance the 4700 sampler has a unique "rotor-moulded" polyethylene construction and superior phenol resin coated refrigeration components. This new design eliminates the problems associated with harsh outdoor locations, and corrosive gases such as H2S.

The 4700 offers a number of features, including four digital alarm outputs, both pulse and 4 to 20mA flow inputs, slide out bottle rack, wide selection of bottle configurations, proven peristaltic pump and non contact liquid detector.

John Morris Scientific are pleased to introduce ISCO’s 6712 portable water sampler for all stormwater, catchment and runoff sampling routines.

The 6712 sampler combines the proven performance and reliability of ISCO water samplers with an in-built data logger and a wide range of plug-in accessories such as; flowmeters, YSI water quality multiprobes, rain gauge, digital I/O and even a modem to contact you when an event occurs.

The ISCO 6712 water sampler forms the basis of a complete stormwater monitoring package. Without the need for sourcing a range of instruments from various suppliers and trying to make it all communicate and interact. ISCO make it easy by allowing you to purchase the accessories you need and simply plug them in. You can add the accessories you need, when you need them.

Isco’s storm water monitoring package has proven reliability for Council stormwater programs, wetlands monitoring, agricultural run-off studies, and a range of other research applications.

The storm water package provides accurate and reliable data, critical to the process of selecting pollutant traps, creating models to examine current and future run-off needs, or when determining pollutants and how to keep them out of our waterways.

Using "off the shelf" components, the major components include a water sampler - to capture both the first flush, and event-weighted run-off; a flowmeter - to trigger the sampler, and determine the pollutant loading; a rain gauge - to record rainfall in the catchment; a suitable power supply such as solar panels and batteries; and ISCO's Flowlink software - to retrieve and analyse the data.
