Introduction

BDCW-50 automatic constant temperature and humidity weighing system is a automatic weighing system developed by Baode, which is based on the condition of weighing various samples such as gas particles, water samples, food, solid waste, and various carriers such as crucibles, evaporating dishes, filter membranes, filter cartridges, and low concentration sampling heads in a closed box with constant temperature and humidity. It is used for monitoring the concentration of particulate matter in ambient air and fixed pollution source exhaust gas An important equipment for ensuring the accuracy of weighing, analysis, and quality control during analysis of dissolved total solids in water samples and determination of moisture content in food and solid waste.

Instrument characteristics

Ø Eliminates weighing results fluctuation caused by unstable temperature and humidity changes in the laboratory environment

Ø Improves stability and accuracy of weighing results such as filter membranes

Ø Improves reliability of sample concentration measurement results.

Ø Achieve automatic large-scale evaporation drying, constant weight weighing, or constant temperature and humidity weighing of various samples and their containers, without the need for laboratory personnel to frequently shuttle between the balance room and the high-temperature room, greatly improving work efficiency.

Ø Equipped with functions such as high-temperature and high-pressure overload protection, without the need for personnel to be on duty, ensuring the safe operation and management of the laboratory.

Applicable projects

Automatic evaporation - constant weight automatic analysis of samples and containers

Ø Total dissolved solids, suspended solids, α/ total β Measurement of radioactive activity and other items in water quality samples such as drinking water, source water, groundwater, surface water, domestic sewage, industrial wastewater, etc

Ø Determination of moisture content and rate in food
