Food heavy metal detector

Product Introduction

The grain heavy metal detector is suitable for the detection of heavy metals cadmium (Cd), lead (Pb), chromium (Cr), arsenic (As), mercury (Hg) and beneficial elements selenium (Se) in rice, rice, brown rice, wheat, corn, beans and other grains and their products. The instrument adopts stripping voltammetry, combined with screen-printed electrodes and simple sample pre-treatment methods, and can be used in the storage, circulation and processing of grain and oil products such as grain depots, grain inspection stations, food processing enterprises, and scientific research institutes. It is suitable for the detection of environmental conditions on the grain purchase site and the results are accurate and stable.

Application Field

The grain heavy metal detector is used in regulatory departments, food production enterprises, agricultural production bases, grain storage, drying, and processing enterprises.

Product Features

1. The detection limit of heavy metals in grain can reach 20ppb, with high accuracy and precision CV < 10%;

2. The detection of a single sample can be completed within 15 minutes. No strong acid heating is required, and the detection of lead and cadmium can be obtained at the same time with one-click;

3. The instrument has built-in instructions and operation videos, and the detection process is simple and easy to operate. Suitable for on-site detection by non-professionals;

4. The instrument is lightweight, equipped with a portable suitcase, and has a battery standby time of more than 4 hours, which is suitable for rapid on-site detection;

5. The instrument uses disposable screen-printed electrodes, which are easy to use and stable, simple and convenient, and do not require expensive consumables and accessories.
