Technical field
The invention belongs to a kind of water quality testing meter technical field, and in particular to a kind of water for multi-parameter water quality detector
Bath thermostat.
Background technology
Multi-parameter water quality detector is processed before needing to carry out before to sample detection, due to impact of the temperature to chemical reaction
It is larger, therefore good sensing chamber's constant temperature system must be designed, to ensure that sample is reacted under the conditions of same temperature.Detection
The constant temperature system of room plays an important role in the whole pretreatment process of sample, only under same environment, just can guarantee that
The repeatability and accuracy of instrument detection.In modern instrument commonly used thermostatic heating method mainly have air bath, water-bath,
Metal such as directly heats at the method.And existing air bath thermostatic mode heat storage capacity is low, easily disturbed by the external world；Metal is permanent
