| Pump | Positive displacement gas pump: 12 VDC, flow rate can be up to 11L/min, continuous pressure 8 psig. |
| Tritium measuring range | 0.2µCi/m3 (7,400Bq/ m3) to 1Ci/m3 |
| 4 chambers | cruciform configuration: two for measuring and two for compensation |
| Radiation measured | measuring total tritium, HTO, gamma and alpha |
| Sensitivity | 0.2µCi/m3 (0.01 DAC) |
| Accuracy | 0.4µCi/m3 from 0 to 100µCi/m3; ±10% from 100µCi/m to 1Ci/m3; |
| Zero stability | ±0.4µCi/m3; |
| Gamma measurement | Gamma is measured simultaneously with tritium. Measuring range is from 0.1mR/h to 10 R/hr; |
| Radon compensation and tritium discrimination | Instrument can provide radon compensation and discriminate in a field of HTO and elemental H3 using the silica gel drier. |
| Gamma background compensation | less than ±10% or 5mCi/m3 reading change whichever is greater response to 20mR/Hr; |
| Ion trap | built into each ion chamber; |

| Response time | 2 to 5s with 0-15 m air hose, within 20s with hose from 100 to 150m at 90% of signal |
| Stability | : ±3% per 24 hours, ±10% per 30 days; |
| Analog Output | 0-3V linear. |
| Alarms | Tritium, gamma, air flow, detector failure, micro processor alarms in field as well as on optional remote display system through analog output (4 to 20mA) |
| Alarm Response | < 30S with 2-150m hose; |
| Purge decontamination | Chambers can be heated by a cartridge heater controlled by the unit to assist in purging, |
| Condensation Prevention | With heater cartridge temperature can be raised above ambient to prevent condensation in instrument |
| Communication port | RS232 (short distance) and RS485-bus (long distance); |
| Data Logging frequency | The tritium value can be logged every minute and can be time and date stamped. (Gamma is not logged) |
