Recommendation for Interim Approval of ASTM International Standard Test Method D888-05 (ATP Case No. N05-0046)
The U.S. Environmental Protection Agency (EPA) has recommended to each of its EPA Regions the use of ASTM International D888-05 Standard Test Methods for Dissolved Oxygen in Water, Test Method C (Luminescence-based Sensor Procedure) for use in measuring DO in wastewater and for use in measuring DO in methods approved at Title 40 of the Code of Federal Regulations, for measuring BOD. The recommended interim approval is to be effective from January 3, 2006 to the effective date of final rules(s) promulgating the method in the Federal Register.
Hach's new portable HQd plug-and-play meters and LDOŽ IntelliCAL(TM) probes offer significant benefits over traditional DO meters based on galvanic or polarographic sensor technology - No membranes to replace, no electrolyte solution, and no electrode polishing required. The new HQd meters offer the unparalleled versatility to take up to two simultaneous measurements of pH, conductivity and LDOŽ with a single meter. It's the first instrument for field and lab use that does not require you to predetermine parameters - buy any probes you need now, and add more later!
Hach's LDO Process Probe offers similar features for on-line monitoring applications, allowing continuous operation with no membranes to replace and minimal maintenance.
