Description

The LR-H108 is a portable temperature and humidity generator designed for the on-site calibration of temperature and humidity sensors within environmental monitoring systems, as well as for use as mobile calibration equipment in metrology support vehicles. It is also suitable for sensor calibration in laboratories, sensor manufacturing facilities, and building environmental monitoring systems. It can function independently as a working standard for temperature and humidity, or serve as a portable generator—when paired with a dew point meter or a higher-precision thermometer—to establish higher-accuracy temperature and humidity standards.

The LR-H108 portable temperature and humidity generator has undergone multiple metrological verifications by the National Institute of Metrology, China (NIM) and the Beijing Great Wall Institute of Metrology and Testing Technology (Institute 304, Aviation Industry). It is currently deployed in the routine inspection of temperature and humidity monitoring systems and within metrology support vehicles for the verification and calibration of temperature and humidity sensors.

The LR-H108 portable temperature and humidity generator integrates advanced controller technology and intelligent sensor technology, combining a temperature generator, a humidity generator, a high-precision temperature measurement system, and a high-precision humidity measurement system into a single, intelligent, and unified unit. This device effectively resolves the long-standing challenge of calibrating temperature and humidity parameters in medium-to-large-scale measurement and control systems, enabling the online calibration of these parameters directly in the field. Capable of simultaneous temperature and humidity testing and calibration, the unit significantly boosts operational efficiency. This instrument fills a critical gap in the domestic market for portable on-site temperature and humidity metrology equipment; it has achieved an advanced international standard and fully complies with the technical requirements outlined in the *JJF1076-2001 Calibration Specification for Humidity Sensors*.
