Despite its small footprint, it integrates a powerful coulometric system with an internal magnetic stirrer, making it ideal for labs where space is limited. The system includes both an indicator and generator electrode (without diaphragm) and supports a recommended measuring range of 10 µg to 200 mg of water, eliminating the need for titer determination due to its absolute measurement method. The intuitive Ipol measuring mode, precise temperature monitoring, and user-friendly interface make the 899 Coulometer a dependable tool for consistent and accurate moisture determination.\u003cbr\u003e\u003cbr\u003e\n\tAll of our equipment is fully tested to perform at factory specifications before being shipped.\u003cbr\u003e\u003cbr\u003e\n\t\u003cdiv class=\"included-box\"\u003e\n\t\t\u003cspan class=\"included-header\"\u003eINCLUDED:\u003c\/span\u003e\u003cbr\u003eThe Metrohm 899 Coulometer includes:\n\t\t\u003cul\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003e Titration Cell\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003e Remote\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003e Power Cord\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003e Operator's Manual\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003e Full 180 Day Parts and Labor Warranty\u003c\/li\u003e\n\t\t\u003c\/ul\u003e\n\t\u003c\/div\u003e\n\t\u003ch2\u003eMetrohm 899 Coulometer Specifications\u003c\/h2\u003e\n\t\u003ctable\u003e\n\t\u003ctbody\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tMeasuring Mode\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\tIpol (adjustable polarization current)\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tPolarization Current\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t5, 10, 20, or 30 uA\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tGenerator Electrode Output\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\tAuto variable DC or pulsating DC at 100, 200, 400 mA\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tMaximum Generator Current\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t400 mA\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tTemperature Sensor Type\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\tPt1000\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tTemperature Measuring Range\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t–150 to +250°C\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tTemperature Accuracy\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t± 0.2°C (–20 to +150°C)\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tStirrer Speed Range\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\tApprox. 1700 to 1900 rpm, 15 steps\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tHousing Material\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\tPBT (base: stainless steel 1.4301)\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tAmbient Operating Range\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t+5 to +45°C, max 85% humidity\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tStorage Temperature\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t–20 to +60°C\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tInterfaces\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\tMSB (Mini DIN), USB OTG, Remote\n\t\t\u003c\/td\u003e\n\t\u003c\/tr\u003e\n\t\u003ctr\u003e\n\t\t\u003ctd\u003e\n\t\t\tDimensions (W x D x H with holder)\n\t\t\u003c\/td\u003e\n\t\t\u003ctd\u003e\n\t\t\t5.7 x 11.1 x 7.7 in.
