I. Product Overview

The cement water-soluble chromium(VI) analyser is designed and manufactured with reference to the national standard GB 31893-2015 《Limit and determination method of water-soluble chromium(VI) in cement》. It is mainly aimed at the cement industry, in particular at determining the water-soluble chromium(VI) content of cement. Standard curves and self-developed rapid reagents are built in, so no curve preparation or reagent formulation is needed by the operator, and a determination takes only 15 minutes (excluding sample pre-treatment). The instrument also provides intelligent data analysis with chart and list displays and an 8-inch HD colour touch screen.

II. Key Features

1. No standard curve preparation or reagent formulation is required, greatly saving testing time.

2. Both the standard (national standard) method and a rapid method can be selected; the indication error is within ±5 % in both cases.

3. Android smart operating system with a user-friendly Chinese interface for faster response and greater stability.

4. 8-inch LCD touch screen with intuitive readout.

5. Imported ultra-bright LED light source with automatic brightness adjustment and calibration.

6. φ16 mm tube colorimetry for more convenient testing.

7. Wireless communication via Wi-Fi, RJ45 and mobile hotspot; data can also be exported through a USB drive.

8. 8 million data sets can be stored; records can be searched by time and selected for analysis.

9. Built-in thermal line printer with freely selectable print content, including QR codes.
