PROBLEM TO BE SOLVED: To obtain a compact thermostat in which a detecting sensor can be simply replaced by holding sensors for detecting the Na, K and Cl ions of an electrolyte analyzer in constant temperature state in a short time. SOLUTION: A pipe for passing warm water of managed constant temperature is embedded in a block 1, which is disposed at the position which is close to the peripheries of detecting sensors 2 to 4. The sensors 2 to 4, a nipple 10 for pressing the sensors and a drive shaft 16 are disposed on one row, a pressing spring 17 is disposed so as to operate a vertical force to the nipple 7 against the sensors 2 to 4, and the sensors 2 to 4 are pressed to a channel block 6 by the nipple 7 by the repelling force of the spring. When the sensors 2 to 4 are removed, a lever 12 provided at the arbitrary position as a rotating center and a cam 14 provided at a gradient in the circumferential direction of the center are disposed, and the shaft 16 is fixed by a clamping pin 15 at the gradient of one point on the circumference. |
