MARC-7000 Aspirator (Tritium Collector)
The MARC-7000 is a device designed to capture tritium (in both vapor and gaseous forms) from the atmosphere for subsequent content analysis. It is not intended for the analysis of samples itself.
1 Capacity of the totalizer (for measuring the volume of the sampled air): at least 25 × 10⁶ dm³.
2 Permissible basic relative error (when measuring an air sample volume of at least 20 dm³): ± 5%.
3 Nominal value of the least significant digit (for volume measurement): 0.1 dm³.
4 Volumetric flow rate setting range for the sampled air: 20 to 40 dm³/h.*
Note: * Factory setting: 30 dm³/h. For other flow rates within the specified range, a calibration factor must be applied.
5 Permissible basic relative error for the volumetric flow rate setting: ± 5%.
6 Nominal value of the least significant digit (for flow rate measurement): 0.1 dm³/h.
7 Air sampling duration measurement range: 1 to 48 hours.
8 Permissible basic relative error for the air sampling duration measurement channel: ± 0.5%.
9 Permissible additional error due to ambient temperature fluctuations (per 10°C deviation from the nominal temperature of 20°C, within a range of -10°C to 40°C): ± 0.5 of the basic relative error.
10 Maximum continuous operating time: 48 hours.
11 Mass of the sampling unit: no more than 30 kg. 12 Overall dimensions of the aspirator, not exceeding:
length: 700 mm;
width: 265 mm;
height: 270 mm.
13 Power consumption: not more than 300 V·A.
14 Power supply from an AC mains: voltage (230±23) V, frequency (50±1) Hz.
