Ordering Information HI839800-01 (115 Vac, USA plug) and HI839800-02 (230 Vac, European plug) is supplied with HI740217 laboratory safety shield; power cable; and quick reference guide with instructions for manual download and instrument quality certificate. HI839800 COD Reactor Programmable with 25 Vial Capacity The HI839800 is a robust, 25 vial capacity thermo-reactor for COD determination of industrial wastewater. The reactor has three stored and three programmable (custom) temperature programs. The stored programs support analysis methods at: · 170 °C (COD methods) · 150 °C (COD methods, Iron Total, Phosphorus Acid Hydrolyzable, Phosphorus Total methods) · 105 °C (Chromium (VI) and Total, Nitrogen Total methods) • Flexibility in supporting applications that require custom programs (time and temperature) • Laboratory safety shield included · The included safety shield is highly recommended to use during vial digestion procedure to maintain a safe working environment • Reactor block temperature continuously evaluated and displayed • Built-in countdown timer · A timer of up to 180 minutes is included for applications that require timed digestions. The end of the digestion time is signaled by 5 short acoustic beeps and “DONE” message is displayed. The heating is turned off and the block begins to cool off. • Status indicator lights · POWER (on) · HOT (surface) · HEATING (in progress) • Overheating prevention • Reference temperature probe well · A small temperature well can accommodate a temperature probe, useful for verifying the heating block. • Warnings and error messages · The instrument displays warning messages when erroneous conditions appear and when values are outside the expected range such as high or low temperature, hot surface, or heating system malfunction. HI740216 Test Tube Cooling Rack HI740217 Lab Safety Shield Use of HI740217 safety shield (included) and HI740216 cooling rack (not included) is strongly recommended. *Reactor displays outside temperature range of 20 – 30 °C (68 – 86 °F) and 170 – 180 °C (338 – 356 °F). Values below 20 °C (68 °F) and above 180 °C (356 °F) are not displayed. 11 COD and Vials 11.37 www.hannainst.com | heating
