AUTOMATIC TESTING APPARATUS IN THERMOSTATIC BATH

PROBLEM TO BE SOLVED: To automate the characteristic test of measuring instruments and apparatuses for a flammable gas, which is performed by using a thermostatic bath. SOLUTION: A heater 1, a cooler 3, a humidifier 4, a thermometer 5 and a hygrometer 6 are provided in order to adjust the temperature and humidity environment inside a thermostatic bath 1 to a test condition, and a flammable- gas detector 10, an emergency evacuation device 11 and an emergency gas shutoff valve 9a which are attached to the thermostatic bath 1 are provided. Then, a signal from the flammable-gas detector 10 is received, and the emergency evacuation device 11 is driven. Thereby, when a flammable gas is leaked into the thermostatic bath 1, it is discharged frocibly to the outside of the bath, and the supply of the gas is cut off so as to eliminate a need that a person watches the thermostatic bath 1 during a test.
