The XZ series multi parameter water quality detector is suitable for concentration detection of large, medium, and small water plants, industrial and mining enterprises, swimming pool disease control centers, domestic or industrial water, in order to meet the prescribed water quality standards. This instrument uses a fully Chinese microcomputer proportional detection and photoelectron colorimetric detection for ion detection, greatly improving measurement resolution.

2、 Performance characteristics

1. Microcomputer, touch sensitive keyboard, backlit high brightness LCD display for numerical values, with full Chinese prompts for operation and calibration process, easy to use. It can automatically zero and calibrate at 5 points, with automatic and manual range switching, and has data nonlinear processing and data smoothing functions.

2. This instrument uses a high-intensity, long-life light source, and a constant light source semiconductor emitter to ensure its light source is stable and has a long lifespan. It does not require preheating when turned on and can be used directly.

3. This instrument also has the function of selective ion measurement, and its light source automatically switches, suitable for rapid quantitative determination of 20 common indicators in drinking water.

4. The host can be equipped with high-power batteries, which can be used for quantitative measurement in the field. Charging for 2 hours can provide continuous use for 4 hours, ready to use, with RS232 printing interface.

5. Adopting a rectangular optical glass colorimetric dish, the surface is smooth and polished, overcoming the measurement error caused by uneven thickness of the tube wall in the circular tube colorimetric dish. It has good repeatability and is more accurate in low range.
