Introduction: The cement free calcium oxide tester is the main indicator to measure the quality of cement and the thermal system of clinker calcination. It adopts the direct titration method of extracting benzoic acid with glycol, and under specific conditions, it only takes 3 minutes to quickly and accurately determine the free oxidation. Calcium content. It can be applied to the production control of cement plants, building materials, scientific research units, teaching buildings of colleges and universities, etc. Technical Parameters: Power supply voltage: 220V 50Hz Power consumption: ≤700W Measuring range: 0-10.00%FcaO Indexing accuracy: 0.01% FcaO Electricity constant: 1±0.2 Control accuracy: ±0.5℃ Constant temperature bath temperature: C±2℃ C- is the set temperature value Temperature setting range: 30-100℃ Environment temperature: 10-40℃ Environmental humidity: <85%RH non-condensing No vibration and strong magnetic field Dimensions: 460×300×260mm (length×width×height) Precautions: 1. The cement clinker sample to be tested must be powder ground to pass through a sieve with an aperture of 0.008, otherwise the reaction speed will be affected and the measurement result will be low. 2. The 50ml reaction flask used must be dry, and no water can be brought in during the measurement. Otherwise, the reaction speed will be affected and the measurement result will be low. 3. The electrical conductivity can be immersed in pure glycol solution during the measurement, and the glycol solution should be replaced frequently. The surface of the platinum electrode may be stained with cement samples during use, which will affect the measurement results , So it needs to be cleaned with dilute hydrochloric acid and distillation, usually 1-2 times/week
