COMET C4130 – Thermo-Hygro-Barometer with Internal Sensors for Temperature, Humidity, and Air Pressure

COMET C4130 – High-Precision Digital Thermo-Hygro-Barometer with Internal Sensors -10 to +60 °C (±0.4 °C), Humidity 5–95 %RH (±2.5 %), Air Pressure 800–1100 hPa (±2 hPa), Dew Point

The COMET C4130 is the high-precision digital thermo-hygro-barometer with integrated sensors – the ideal measuring instrument for complete indoor climate monitoring of temperature, relative humidity, dew point, and barometric pressure in offices, warehouses, climate chambers, server rooms, museums, archives, greenhouses, the pharmaceutical industry, or anywhere the entire climate needs to be measured and documented simultaneously. With a measuring range of -10 to +60 °C, 5 to 95 %RH, air pressure 800 to 1100 hPa, and a traceable calibration certificate, it is perfectly suited as a reference or test instrument for demanding applications.

The device measures with internal sensors – no external probes required, ready for immediate use. The acoustic and visual alarm provides instant warnings when freely adjustable limits are exceeded. The Min/Max memory shows the extreme values since the last power-on. The backlit LCD display is easy to read, and the measuring rate (0.7 to 5 s) and display update interval are adjustable. The robust housing (IP20) and battery power supply (9 V block battery or 12 V mains adapter with NiMH battery) make it mobile and independent of the mains – battery life approx. 4 months.

The thermo-hygro-barometer is maintenance-free, long-term stable, and comes with a 3-year warranty. The included traceable calibration certificate ensures maximum measuring accuracy ex works. Intuitive operation via buttons and a clear menu. Whether as a portable device for field use, a climate monitor in production, or a reference instrument in the laboratory – the C4130 convinces with precision, reliability, and ease of use. The additional air pressure display with the tendency of the last 3 hours is unique in this class.
