Testo 315-1, CO leakage alarm device, including battery and factory report& nbsp; Product introduction: CO leakage may lead to poisoning hazards. Teste 315-1 detects the CO content in indoor air and simultaneously measures pressure, wind speed, ionization current, and temperature< Br/>It is an ideal instrument for safe maintenance of gas heating systems. The testo printer prints data, address, date, time, and alarm limits on-site& nbsp;  Advantages: 3 CO alarm limits, optional sound and light alarm when exceeded. DVGW certification on-site for quick data archiving, printing data, time, date, and recommended values (alarm limits). Temperature compensation does not need to be zeroed in fresh air
