Heavy metal detector

Abstract

The invention discloses a heavy metal detector. The detector comprises: a base; a detection mechanism which is connected to the machine base and comprises a test pool for bearing a detection solution and an electrode plate extending into the test pool; a temperature conduction metal piece which wraps the periphery of the testing pool; a temperature adjusting mechanism which is mounted on the temperature conduction metal piece to heat or refrigerate the temperature conduction metal piece; and a temperature sensor which is used for detecting the temperature of the solution in the testing pool and is connected with the temperature adjusting mechanism. The temperature sensor is used for monitoring the temperature of the testing pool in real time, and the temperature adjusting mechanism controls the temperature of the testing pool and keeps the temperature of the testing pool through the temperature conduction metal piece, so that the testing pool can be kept in a preset temperature range constantly, a solution sample in the testing pool is prevented from being influenced by external temperature, and the accuracy and precision of a detection result are greatly improved.

Description

technical field [0001] The invention relates to detection equipment, in particular to a heavy metal detector. Background technique [0002] At present, the heavy metal detectors on the market do not use constant temperature devices. The temperature difference between winter and summer is relatively large. The change of temperature will have a certain impact on the results of heavy metal equipment detection, which leads to the results of heavy metal detection. Sometimes the results are more accurate, sometimes The time difference is relatively large. At present, the constant temperature control on the market only uses the equipment to preheat, let the equipment work for a certain period of time, and increase the temperature inside the equipment through the heating of the hardware components in the equipment. However, this method can only increase the temperature inside the equipment in a relatively small range, and cannot be realized. Refrigeration, so it hardly improves the...

[0002] At present, the heavy metal detectors on the market do not use constant temperature devices. The temperature difference between winter and summer is relatively large. The change of temperature will have a certain impact on the results of heavy metal equipment detection, which leads to the results of heavy metal detection. Sometimes the results are more accurate, sometimes The time difference is relatively large

At present, the constant temperature control on the market only uses the equipment to preheat, let the equipment work for a certain period of time, and increase the temperature inside the equipment through the heating of the hardware components in the equipment. However, this method can only increase the temperature inside the equipment in a relatively small range, and cannot be realized. Refrigeration, so there is little improvement in equipment performance

The temperature cannot be accurately controlled, and the unstable temperature will lead to a large deviation in the test results
