TAKACHIHO TPD-1100 Hazardous Gas Detector (Oxygen, Methane, Carbon Monoxide, Hydrogen Sulfide)

Features

• Sensor replacement is done manually.
• No inspection period required.
• Unit replacement system (equipped with 4 sensors and a suction pump).
• You can easily replace the unit yourself without needing to leave it at the factory. Replacement is required every year.
• The water trap has a finger rest.
• It features four types of gases (oxygen, methane, carbon monoxide, and hydrogen sulfide) plus temperature and humidity control.
• Up to 4000 measurement logs are automatically saved. You can transfer the data to a USB memory stick and manage it on your computer.
• Self-diagnosis function: Automatically detects abnormalities in the main unit. Sensor abnormalities and measurement abnormalities are displayed on the screen.
• The detector unit's outer frame also features an alarm lamp. When there is noise or when measuring with the lid closed, the alarm lamp on the outer frame will also alert those nearby to any abnormalities.
• The gas detector is equipped with a temperature and humidity display. Customers can select a heatstroke warning mode, and the alarm will provide guidance to alert them.
• IP67 waterproof and dustproof rating. Equipped with a new external alarm with 10m drop resistance. The alarm lamp's visibility angle has been expanded to all directions, adding a safety feature for early detection of abnormalities. Abnormalities are notified by alarm sound, alarm lamp, and voice guidance.
• Equipped with a 10m gas inlet pipe and external alarm.
• *While measurement data can be extracted in CSV format using a USB memory stick, data management software (sold separately) is required if you wish to print the data in a format such as a measurement record sheet.
