Abstract

The invention discloses an environment-friendly high-precision constant-temperature and constant-humidity weighing device. The environment-friendly high-precision constant-temperature and constant-humidity weighing device includes a base, a housing, a constant temperature box and an operation box, the housing is provided with at least two lower cabinet chambers below the operation box; a water supplementing tank is fixed at the top of the housing; the operation box is of a rectangular frame structure with an opening facing a moving door, and the rectangular frame structure is composed of a left constant-temperature plate, a right constant-temperature plate, a rear constant-temperature plate, an upper constant-temperature plate and a lower constant-temperature plate. Three circulating fansare arranged on the rear constant-temperature plate; heating coils are arranged on the left constant temperature plate, the right constant temperature plate, the rear constant temperature plate, the upper constant-temperature plate and the lower constant-temperature plate; a steam inlet is formed in the upper end of the rear constant-temperature plate; a condenser is arranged on the steam inlet, adamping table and a sample frame are fixed to the lower constant-temperature plate, a weighing balance is fixed to the upper end of the damping table, a humidifier is fixed into one lower cabinet chamber, water with large specific heat capacity serves as a heat conduction medium to heat an operation box connecting pipe through five-face type heat exchange, and heat transfer is more uniform.

Description

technical field [0001] The invention relates to the technical field of detection and weighing equipment for ambient air and fixed pollution source particles, in particular to an environment-friendly high-precision constant temperature and humidity weighing device. Background technique [0002] Ultra-low smoke detection requires the use of a constant temperature and humidity weighing environment. Due to the small weight of smoke, airflow disturbances and tiny vibrations will affect the accuracy of weighing. Some existing weighing equipment may easily lead to inaccurate weighing due to the detection environment. The existing equipment adopts heating tube heating, and the cooling and temperature control of the condensing tube has large vibration and is easily disturbed. The one-piece structure of the traditional thermostat has compressor vibration and noise problems, which cannot meet the requirements of precise micro-pressure measurement. Contents of the invention [0003] ...
