COMPARING THE ACM TO GAS DETECTORS
| FEATURE | TELOSENSE ACM | GAS DETECTORS |
|---|---|---|
| SPEED OF DETECTION | SCANS PORTS AT 20 TO 30 SECONDS PER SAMPLE PORT. UP TO 13 CHEMICALS ANALYZED PER 20-30 SECOND SCAN. OPTION: COMPOSITE SCAN VERSION | 30 TO 60 SECONDS TO 1 TLV |
| LONG TERM CALIBRATION STABILITY | FTIR ANALYZER DOES NOT DRIFT CALIBRATION IS ENTERED IN SOFTWARE AND IS PERMANENT | DEGRADES OVER SHORT PERIOD OF USE - MUST BE TESTED MONTHLY |
| SELF-TESTING: YOU “KNOW IT IS WORKING” | VALID IR SPECTRUM, IR THROUGHPUT AND SAMPLE FLOW ARE CONSTANTLY CHECKED BY COMPUTER | CHECKS CABLE FAULT BUT “YOU NEVER KNOW IT IS REALLY WORKING” |
| CALIBRATING WITH A GAS STANDARD | RECALIBRATION NOT REQUIRED. MAY BE TESTED ON ONE PORT WITH ONE GAS | MUST LOCATE AND CALIBRATE EVERY GAS DETECTOR |
| COST EFFICIENCY: CAPACITY FOR GASES AND IDENTIFICATION OF GAS TYPE | UP TO 15 GASES PER PORT MONITORED AT THE SAME TIME; EACH SPECIFICALLY IDENTIFIED AND QUANTIFIED | A DETECTOR IS NEEDED FOR EACH GAS TYPE AND FOR EACH POINT. LIMITED GAS IDENTIFICATION |
| COST EFFICIENCY: CAPACITY FOR PORTS | 40 PORT CAPACITY | 40 ACM PORTS HAS A MONITORING CAPACITY EXCEEDING 400 GAS DETECTORS |
| COST OF OWNERSHIP: SERVICE ATTENTION AND PARTS COST | TWICE PER YEAR. PM & SERVICE PARTS COST LESS THAN $5,000/YEAR | CALIBRATE EVERY 1-3 MONTHS; REPLACE EACH SENSOR HEAD EVERY YEAR AT ~ $300/SENSOR |
