Chemical oxygen demand determination Easy to use biological oxygen demand equipment The HydroTest COD system (HTCOD) is a simple and flexible solution to measurement of this important environmental test targeting wastewater. The HTCOD includes a digestion block (requires mains electricity) to react your COD vessels, a photometer to read your samples and a complete set of reagents and accessories. Biological Oxygen Demand (BOD) is the amount of oxygen used by micro-organisms when they degrade organic material in a water sample and is an indication of contamination. Capable of measuring from 0 to 15,000 mg/L Mercury free dichromate method Visual or Electronic systems Simple handling Reactor also suitable for digestion of other products in the HydroTest range Simple manometric method Photometer, reactor, consumables and accessories all included TECHNICAL SPECIFICATION Photometer This conventional system comprises of 6 bottles and 6 mercury capillary tubes with a constant scale up to 1000 mg/L. Maintenance free system with programmable stirrer and direct BOD reading. 3 Preinstalled COD programmes Portable and suitable for one-handed operation Chemically resistant housing LED Light source CE Conformity, IP68 Data download via IR link or USB Microprocessor controlled 24 x 16.2 mm hole aluminium block Splashproof membrane keypad Safety screen +/- 1°C temperature accuracy 220-240 V Overheat protection CE Conformity 3 ranges Є LR: 0 – 150 mg/L Є MR: 0 – 1500 mg/L Є HR: 0 – 15000 mg/L Packs of 25 tests Premeasured reagent Mercury free dichromate method System supplied complete with 6 of: Є 500 ml amber glass bottles Capillary caps 35 mm magnetic stirrer bars PART NUMBER Standard 6 bottle BOD system Standard 6 bottle spares kit PART NUMBER HTCOD Photometer- no case HTCOD Thermoreactor- no case COMPONENTS REAGENTS
