More About This Item

The Traceable® 9009TR Professional Thermohygrometer provides reliable environmental monitoring in a portable handheld format. Designed for users who require accurate humidity and temperature measurements, the meter delivers comprehensive environmental data including relative humidity, ambient temperature, dew point, wet bulb temperature, and absolute humidity calculations.

The instrument is particularly well suited for monitoring controlled environments such as laboratories, cleanrooms, pharmaceutical facilities, warehouses, production areas, storage rooms, and HVAC systems where precise environmental conditions are critical to product quality, regulatory compliance, and operational performance.

A large backlit LCD display provides easy viewing of readings in dimly lit environments, while the meter's ergonomic design allows for comfortable handheld operation during inspections and environmental assessments.

The ability to measure dew point and wet bulb temperature makes the instrument valuable for moisture control studies, HVAC troubleshooting, facility management, and environmental qualification applications. Absolute humidity measurements provide additional insight into actual moisture content within the air.

Min/Max and Hold functions allow users to capture critical readings and review environmental fluctuations, while automatic power-off conserves battery life during routine field use.

The double-molded heavy-duty housing helps protect the instrument from everyday wear and tear, making it suitable for use in industrial, laboratory, healthcare, and commercial facilities.

Every Traceable® thermohygrometer includes an individually numbered Traceable® Certificate documenting traceability to SI units through NIST or other recognized National Measurement Institutes (NMIs). Calibration is performed by an A2LA-accredited ISO/IEC 17025 laboratory, supporting laboratory accreditation, quality assurance programs, regulatory compliance, and audit documentation requirements.

Guaranteed to have at least one year of calibration remaining on the certificate.
