An enhanced model of a circulating water bath for fecal coliform and Escherichia coli testing has been introduced. The Model 8306 Circulating Water Bath is set to the 44.5°C temperature required for APHA, AWWA, WEF, and EPA fecal coliform determinations. This water bath also incorporates three user-settable presets to provide one-touch temperature selection for other regularly performed coliform and E. coli tests.
The Model 8306 features an ambient +5° to 150°C temperature control range of + or – 0.05°C temperature stability, 28-liter reservoir, and bright LED readout. Other standard features include integral over-temperature and low-liquid level safeties, hinged see-through bath cover, and two-speed pump suitable for both internal and external circulation. All wetted parts are corrosion-resistant 300 series stainless steel.
