Wide-range temperature adjustment and pH value measurement device

Abstract

The invention discloses a wide-range temperature adjustment and pH value measurement device, and the device comprises a temperature control device, a detection device and a pipe. The temperature control device comprises a water bath circulation pool, a water bath heating block, an electric heating film, a cooling sheet and a heat sink, wherein the water bath heating block is disposed at the bottomof the water bath circulation pool, and the electric heating film is disposed at the side of a pool wall of the water bath circulation pool. The cooling sheet is disposed at the other side of the pool wall of the water bath circulation pool, and is opposite to the electric heating film. The heat sink is disposed on an outer side wall of the bottom of the water bath circulation pool. The detectiondevice comprises a temperature control pool, a detection pool, a temperature sensor and a pH-value sensor, wherein the detection pool is disposed in a temperature control tank, and the temperature sensor is disposed on the pool wall of the temperature control pool. The pH-value sensor is inserted into the to-be-tested liquid in the detection pool, and the temperature control tank is connected with the water bath circulation pool through the pipe. The device has a wide temperature control range, saves energy, is environmentally friendly, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of measuring devices, in particular to a device for wide-range temperature regulation and pH measurement. Background technique [0002] In the fields of industry, electric power, agriculture, medicine, food, scientific research and environmental protection, it is necessary to accurately control the pH value of the solution, and the key step in controlling the pH value of the solution is to obtain the pH value of the solution. [0003] Most of the pH measuring instruments in the prior art do not have a temperature control device, or the controllable temperature range of the temperature control device is small, which cannot meet the needs of detection. SUMMARY OF THE INVENTION [0004] Aiming at the deficiencies of the prior art, the present invention provides a device for wide-range temperature regulation and pH measurement, which has a wide temperature control range, is energy-saving and environment-friendly, and is...
