This device can measure both lime and cement dosage, as well as the effective calcium oxide content in lime.

Multifunctional Direct-Reading Calcium Analyzer

Model:WJJHC-1

I. Product Introduction of WJJHC-1 Multifunctional Direct-Reading Calcium Analyzer

The WJJHC-1 Multifunctional Direct-Reading Calcium Analyzer is developed and manufactured by Hebei Tianqixingzi Inspection Equipment Co.,Ltd., based on T0810-2009 "Method for Determination of Lime Dosage in Lime-Stabilized Materials" in JTG E51-2009 "Test Procedures for Inorganic Binder Stabilized Materials in Highway Engineering".Meanwhile, the equipment design references European standard EN 196-2 — Methods of testing cement — Part 2: Chemical analysis and American standard ASTM C114 — Chemical Analysis of Hydraulic Cement, making it meet international testing method requirements and suitable for export.

The WJJHC-1 multifunctional direct-reading calcium analyzer can measure both lime and cement dosages, as well as the effective calcium oxide content in lime. The instrument can be powered by DC or AC. When using DC power, remove the battery compartment cover at the bottom of the instrument and insert four size D batteries. For 220V AC power, insert one end of the AC/DC converter into the "Power" jack on the back of the instrument to operate.
