The invention provides a wide-temperature-range accurate temperature control water bath tank for a laboratory, belongs to the technical field of water bath tanks, and aims at solving the problem thatin an existing wide-temperature-range accurate temperature control water bath tank for a laboratory, when a measured liquid is heated or refrigerated in a liquid bath, the temperature of the measuredliquid is prone to being influenced by the external environment temperature and cannot be accurately controlled, and consequently the accuracy of a measurement result is reduced. The water bath tank comprises a wide-temperature-range water bath tank body, and a supporting device is welded to the bottom of the barrel wall of the wide-temperature-range water bath tank body at a certain height. A motor provides power, and the rotating shaft of the motor drives an outer magnet to rotate, so that a stirring magnet in the wide-temperature-range water bath tank is driven to rotate through a magneticfield, and the purposes of stirring bath liquid and homogenizing temperature are achieved; and meanwhile, two electric heating pipes are both of an annular structure, heating wires with different powers are distributed in the two electric heating pipes respectively, heat output with different powers can be provided in a combined mode, bath liquid is rapidly heated, and the experiment efficiency isimproved.
Description
technical field [0001] The invention belongs to the technical field of water baths, and more specifically relates to a water bath with wide temperature range and precise temperature control for laboratories. Background technique [0002] When conducting tests in laboratories, it is necessary to maintain the temperature of various liquids to be tested, and these temperatures are widely distributed, ranging from -10-100°C. The temperature distribution of the daily laboratory ranges from 10-30°C, so it is necessary to heat up or cool down the liquid to be tested to reach the required specific temperature and maintain it to meet the needs of the experimental conditions. [0003] For example, the invention of application number: CN201921362216.7 discloses a water bath box, which includes a box body provided with a water bath, the water bath is provided with a door, a heating device and a temperature control device; a supporting beam, and the water bath is provided with a There i...
