Micro Balance
CM-F Filter Micro Balance
The Aczet CM-F Series filter micro balances are made for weighing filters in particulate-matter and emission testing. Four models (CM 2F, CM 5F, CM 6F and CM 11F) cover 2 g to 11 g with 1 µg readability and a 50 mm filter pan under a cylindrical aluminium draft shield that limits electrostatic influence. Motorised internal calibration, a backlit LCD with ten built-in applications, RS 232C output (USB optional) and GLP-ready time stamping make it practical for environmental testing and research labs.

Key features of CM-F Filter Micro Balance
1 µg readability, four capacities
The CM 2F, CM 5F, CM 6F and CM 11F cover 2 g to 11 g, all with 1 µg (0.001 mg) readability.
Filter weighing chamber
A 50 mm pan under a cylindrical aluminium draft shield limits electrostatic influence on filters, for PM10 and PM2.5 testing.
Automatic internal calibration
Motorised built-in weights plus PSAC recalibrate the balance on a temperature change or after a set time.
Separate electronics and measuring cell
The two-part design keeps heat from the electronics away from the mechanical cell, with a stainless steel housing for fast stabilization.
GLP-ready records
Built-in real-time clock, RS 232C output (USB optional) and ten built-in applications support traceable, error-free documentation.
Key advantages of CM-F Filter Micro Balance
Right size for the filter job
Choose 2, 5, 6.1 or 11 g capacity in one series and keep the same 1 µg readability.
Low sensitivity drift
Sensitivity drift is stated as ±1 ppm per °C, so results stay steady across the 18 to 30 °C operating range.
Easy to clean and level
Draft shields come apart without tools and a level indicator with adjustable feet helps you set the balance up correctly.
Overload protection
The built-in capacity tracker on the display shows how close you are to the limit and helps protect the weighing cell.
Room to add accessories
Optional touch-free operation, an ionizer, a printer, an anti-vibration table and 21 CFR Part 11 software can be added when you need them.
About CM-F Filter Micro Balance
The Aczet CM-F Filter Micro Balance is a microbalance range built for one job: weighing filters accurately. Aczet describes these balances as ideal for measuring particulate emissions, and they can monitor the particle classes PM10 and PM2.5, particles smaller than 10 µm and 2.5 µm. They suit research and testing institutes in environmental technology, where air pollution from vehicles, power plants and other motorised equipment is monitored and controlled.
Four models, 1 µg readability
CM 2F: 2 g capacity.
CM 5F: 5 g capacity.
CM 6F: 6.1 g capacity.
CM 11F: 11 g capacity.
All four read to 1 µg (0.001 mg) and share a 50 mm diameter pan, a minimum load of 100 µg and a response time of 8 to 10 seconds.
Designed for filter weighing
A specially designed weighing chamber with a cylindrical aluminium draft shield reduces the influence of electrostatic charges on the filter weight.
The stainless steel housing gives short stabilization times and keeps heat transfer from the electronics away from the weighing cell.
The draft shields can be dismantled and assembled easily, so cleaning is quick.
The balance has two parts, a mechanical measuring cell and a separate electronics box, so the electronics do not warm the measuring cell.
Proven weighing technology
The sensor works on electromagnetic force compensation (EMFC). Motorised built-in weights calibrate the balance internally, and the Perfect Self Automatic Calibration (PSAC) function repeats the calibration when the temperature changes or a set time has passed. A capacity tracker on the display helps you avoid overloading the weighing cell.
Operation and documentation
A bright backlit LCD with large digits and ten built-in applications (including density determination, check weighing, totalling and formulation) simplify routine work. RS 232C output (USB optional) and a built-in real-time clock support error-free, traceable records for GLP and GMP. Options listed by Aczet include a touch-free infrared draft shield, a CI-01 anti-static ionizer, a dot-matrix data printer, 21 CFR Part 11 PC software, an anti-vibration table, test weights and a battery backup.

Frequently asked questions: CM-F Filter Micro Balance
Aczet lists four models: CM 2F (2 g), CM 5F (5 g), CM 6F (6.1 g) and CM 11F (11 g). All read to 1 µg (0.001 mg).
It weighs filters before and after sampling to measure particulate emissions. Aczet states the balances can monitor PM10 and PM2.5 particles, which suits environmental testing of vehicle, power plant and other exhaust and evaporative emissions.
Aczet's product page lists a 50 mm diameter pan for all four models. Please tell us the diameter of the filters you use so our team can confirm it fits.
It has motorised internal calibration with built-in weights. The Perfect Self Automatic Calibration (PSAC) function repeats the calibration automatically when the temperature changes or after a defined time.
The minimum load is 100 µg on every model. The minimum sample weight is 0.1 mg for the CM 2F, 0.2 mg for the CM 5F and 0.24 mg for the CM 6F and CM 11F. The minimum sample weight as per USP is 1 mg, 2 mg, 2.4 mg and 2.4 mg respectively.
The balance has an RS 232C interface, with USB (Windows direct communication) as an option. A dot-matrix data printer and 21 CFR Part 11 PC software are listed as accessories.
The weighing chamber has a cylindrical aluminium draft shield made to reduce the influence of electrostatic charges. Aczet also offers an optional CI-01 anti-static ionizer for extra protection.
Aczet gives the operating temperature as 18 to 30 °C. Install it on a stable bench, and an anti-vibration weighing table is available as an accessory if the floor or bench vibrates.
