  • SP-220 works as Leak Checker and TLV Detector. Competitor instruments either work as Leak checker or TLV detector.
  • SP-220 has in built pump for fast response. Competitor models are diffusion type only. This leads to slow response.
  • SP-220 needs Calibration after every 1 year, Unlike Competitors which requires calibration every 6 months. Time taken by Tritech for Calibration is only 1 day this cannot be said about competitors.
  • Same SP-220 can be used to detect MBr & Ph3 gases just by change of setting by user himself. Competitors Instrument only detects 1 gas.
  • SP-220 uses long life & reliable solid state sensor same as previous Model: GH-202F. These instruments have long life more than 10-15 years. depending on usage. Such long life and reliability is missing in competitors products.
  • SP-220 has Rubber coated, tough enclosure which is ATEX approved and IP55 certified. Competitors offer plastic housing.
