Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a particle measuring apparatus and method enabling the particle measuring apparatus to be effectively protected from an excessive high and/or low temperature.SOLUTION: This problem is resolved by the following invention. The temperature of a test gas is measured upstream of a first test gas process sensitive to temperature or a test gas measuring device of a particle measuring apparatus. The measured temperature is compared with a first and/or second limit value. When the measured temperature is higher than the first limit value or is lower than the second limit value, the particle measuring apparatus is switched to a safety mode. 【課題】本発明の課題は、あまりに高い及び／又はあまりに低い温度から粒子測定装置が効果的に保護されることが可能である粒子測定装置及び方法を提供することである。【解決手段】この課題は、発明に従い、試験ガスの温度が、粒子測定装置内で、温度に対して敏感な第一の試験ガス処理または試験ガス計測装置の流れ上流で計測され、そして計測された温度が、第一及び／又は第二の限界値と比較され、そして測定された温度が第一の限界値を上回るか、または第二の限界値を下回るとき、粒子測定装置が、安全なモードに切り替えられることによって解決される。【選択図】図１
