Product introduction:

The ADM-870C gas multifunction meter is designed for applications where air is very demanding. The unique feature of the ADM-870C gas multi-function meter is that it is ideal for maintaining air quality. It is commonly used in hospitals, pharmaceutical plants, biological or chemical research laboratories, semiconductor manufacturing purification rooms and other demanding places. .
The RS232 communication port of the ADM-870C Gas Multimeter allows the user to download readings to a printer or computer, and the readings can be downloaded independently or in sequence. Optional user interface software allows readings to be automatically transferred to Excel or similar spreadsheets. Wind speed and air volume readings can be displayed as wind speed or volumetric flow at standard density equivalent to mass flow meter readings or at local density, compensated by different atmospheric pressures or temperatures.
The Auto-read Auto-Read feature of the ADM-870C Gas Multi-Function Meter allows for continuous changes to be monitored in an adjusted system to monitor ongoing changes. Auto-read can also be used for memory functions to automatically store up to 200 data. Each reading is traceable and displayed in the average/total reading format. The average function is designed to test the environment that changes up and down. Differential pressure and temperature These wind speed related readings can quickly display measurements that follow each wind speed.
The ADM-870C Gas Multimeter provides digital display readings in English or metric units at local or standard density. Features include auto-read auto-read, storage in total/average format, associated pressure, temperature display, VelGrid, AirFoil wind speed test probe and serial output to printer or computer. Measure the air flow rate, total pressure or differential pressure, temperature, etc. When using the 8400 series air volume cover, the air volume under back pressure compensation can be measured.

Product Features:

1, smoke compartment and clean room test: VelGrid is designed for surface speed testing such as exhaust cabinets. Efficient clean room HEPA filter outlet, laminar flow workstation, large filter, etc. Each reading represents the result of the input of 16 wind speed points in one square foot. A 54-inch adjustable extension handle and a wide band that can be hung around the neck make it easy to position the VelGrid.
2, differential pressure measurement: can be from 0.0001 to 60.00 inches of water column wide range and has a high degree of precision. If it is sensitive, the instrument can withstand a differential pressure of 20 PSI and has no adverse effect on the instrument. There is no zero offset due to linear pressure or distance correction. Although the design is hand-held and used in the field, the sensitivity of this instrument has reached some micro-pressure gauge levels in the laboratory.
3, temperature: ADT440 TemProbe temperature probe series can be suitable for wet bulbs, dry bulbs and water pressure temperature. The optional 8-point AirData MultiTemp (Air Data Multi-Point Sensor) is the ideal efficiency test tool for air conditioning units and heat exchangers.
4, automatic zero adjustment and range selection: internal calibration, temperature compensation, range selection and zero adjustment are all fully automated with readings, no external calibration required
5. Flow and Flow Rate: Automatic correction of gas flow and flow rate readings causes changes in air density based on local atmospheric pressure and temperature changes. Displays readings in the standard concentration range (equivalent to mass concentration accuracy) and flow rate and flow readings at local density
6, air balance measurement: When an air volume cover is connected to the unit under test, the air output will be reduced. This "back pressure" causes a decrease in flow rate that is different from a decrease in the amount of air from one output port to the other or a decrease in the set air volume due to the regulating valve. The 8400 Series Airflow Shield represents a major technological breakthrough in direct air volume measurement at the inlet and outlet. Back pressure compensated and uncompensated readings are independently recorded in memory and can show the average/total value of each test. The air data multimeter easily mounts the upwind mask unit and integrates into its instant microprocessor. The energy is calculated based on the unique flaps function of the airflow hood, and each air volume reading can be compensated for due to back pressure.
The airflow hood kit includes basic measurement section accessories such as wind speed flat grid brackets, different top size combinations and a sturdy transport wheel box.
7, air duct wind speed test: In the past when doing the pitot tube to measure the wind speed, two people are needed. With this instrument, only one person can be used. Each reading is taken within 10 seconds and stored in memory. Each reading can be traced. AirFoil probes are commonly used for single point wind speed measurements. The straight rod design makes it easy to use in piping systems.
8, the instrument can store up to 200 sets of data: the instrument can store up to 200 data can be easily traced later. Includes pitot test readings, average face velocity, temperature and static pressure readings, and output readings, etc.
